shown in Table 1, then there are different figures for units based on an MOCP below or above 60 Amps. Use the correct figure based on the MOCP determined from the correct electrical data table. Figures 11-15 are for electric cooling units. Figures 16-20 are for heat pump units. Figures 21-28 are for COBRA combined rooftop/energy recovery units. All fuses are 60 amp, time delay type, except for CRSINGLE025A00 which are 30 amps. All heaters are single bank heaters except CRHEATER011A00 and 012A00 which are dual bank heaters. The CRHEATER011A00 and 012A00 will be wired as two heaters (i.e., 6 leads). Fusing is shown pictorially. The single point box fuse location may not EXACTLY match the figure as shown, but the number of fuses will match the number shown. The optional factory-supplied disconnect has a maximum rating of 80 amps. Above 80 amps a fieldsupplied disconnect is required. Single point boxes CRSINGLE001A00, 006A00 and 011A00 do not include fuses and fuses are not required per the National Electric Code in these single point boxes since sub-fusing is not required below 60 amps. Field-supplied pressure connectors are required to connect wires. 12. Run control wires from heater module(s) to the control wire terminal block located next to the heater module(s). Connect the control wires as shown in Fig. 29. Heat Pump Units The electric heat is internally wired as the second stage of heat. Electric Cooling Units Electric cooling units with 2 electric heater modules can be wired for one- or 2-stage options as shown in Fig. 29. Connect single module heater option control wire (violet) to TB4 terminal 1. 13. Replace the center post and secure the single point box to the center post with one screw (Fig. 3).
7. To install module, engage flange on heater with track in unit and slide heater through mounting bracket opening. Fasten heater module to heater mounting bracket with the 4 screws saved from Step 6 (Fig. 4). NOTE: All 208/230-v heaters (except CRHEATER 105A00) are factory-wired for 3-phase applications but can be converted to single-phase by changing one wire as described in Step 8. Three-phase applications: Skip to Step 9. 8. On single-phase applications, rewire the heater as follows (see Fig. 8-10): a. Connect 10-gage red wire to splice connector. b. Remove yellow wire from heater contactor terminal 11 and connect to splice connector. c. Using the wire tie provided, fasten red wire to heater power wire harness near existing wire tie on heater module. This provides strain relief for the red wire. 9. Route power wires from heater module(s) through the foam bushing in the center partition and into the single point box (Fig. 4). If no single point box is required for the unit and heater combination, run the heater high voltage power wiring through the grommet holes to the field-supplied disconnect (or optional factory-supplied 80 amp disconnect). Heater control wiring should be run to the control box section. 10. Install bushing in hole between control box and single point box. Route unit power pigtails through bushing (Fig. 4). 11. See Table 1 to determine the correct electrical data table. Refer to Electrical Data Tables 2-25 to determine the heater and single point box. From the Electrical table determine the MOCP with heaters and accessories, the number of heaters, and the CRSINGLE---A00 part number. The correct figure can be determined using Table 1. The unit type (cooling only, heat pump, or COBRA™ combined unit), efficiency type (high, standard ASHRAE 90.1 compliant, standard), and the unit voltage are listed in Table 1.

*Used to determine minimum disconnect per NEC. †Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v or 575 v. If power distribution voltage to unit varies from rated heater voltage, heater kW will vary accordingly. NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance max voltage deviation from average voltage = 100 x average voltage
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately. 3. Non-fused disconnect switch cannot be used when rooftop unit electrical ratings exceed 80 amps. 4. 575-v units have UL, Canada approval only. Electric heaters are not available for 3 to 6 ton, 575-v units.

*Two heater packages required to provide kW indicated. †004 on units with convenience outlet. **002 on high-static units with convenience outlet. NOTES: 1. The rated heater voltage is 240, 480, and 575 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly. 2. To determine heater kW at voltages other than those shown in table, use the following formula: Heater kWnew = Heater kW rated x (unit power distribution voltage/rated heater voltage)2 As an example: For a 16 kW heater rated at 240 v with a power distribution voltage of 215 v kW new = 16 kW (215/240)2 kW new = 12.8 kW (rating at 215 v)

IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately. 3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance max voltage deviation from average voltage average voltage
Example: Supply voltage is 460-3-60. AB = 452 v BC = 464 v AC = 455 v Average Voltage = =
7 457
= 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker.

= 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.
*Used to determine minimum disconnect per NEC. †Fuse or HACR circuit breaker. **Fuse only.
3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance = 100 x

= 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.
*Used to determine minimum disconnect per NEC. †Fuse or HACR circuit breaker. **Fuse only.
3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance = 100 x

IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately. 3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance max voltage deviation from average voltage average voltage
Example: Supply voltage is 460-3-60. AB = 452 v BC = 464 v AC = 455 v Average Voltage = =
7 457
= 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

= 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.
*Used to determine minimum disconnect per NEC. †Fuse or HACR circuit breaker. **Fuse only.
3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance = 100 x

3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 71/2 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.
Example: Supply voltage is 460-3-60. AB = 452 v BC = 464 v AC = 455 v Average Voltage =
307/307
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.
*Used to determine minimum disconnect per NEC. †Fuse or HACR circuit breaker. **Fuse only. NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance = 100 x
LRA
Determine percent of voltage imbalance. 7 % Voltage Imbalance = 100 x 457 = 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 5 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance.
Average Voltage =
60/ 60 60/ 60 60/ 60 80/ 90** 100/110** 110/125** 60/ 60 60/ 60 60/ 60 80/ 90** 100/110** 110/125** 40/ 40 40/ 40 45/ 45 60/ 70** 70/ 80** 90/100** 40/ 40 40/ 40 40/ 45 60/ 60 70/ 80** 90/100** 40/ 40 40/ 40 45/ 50 60/ 70** 80/ 80** 90/100** 20 20 25 30 45 45 20 20 25 30 45 45 20 20 25 30 45 45 15 15 15

Determine percent of voltage imbalance. 7 % Voltage Imbalance = 100 x 457 = 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.
*Used to determine minimum disconnect per NEC. †Fuse or HACR circuit breaker. **Fuse only.
3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). Determine the new MCA including the power exhaust using the following formula: MCA New = MCA unit only + MCA of Power Exhaust For example, using a 71/2 ton unit with MCA = 28.9 and MOCP = 35, with CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 35 amps, the MCA New is below 35, therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance max voltage deviation from average voltage = 100 x average voltage Example: Supply voltage is 460-3-60. AB = 452 v BC = 464 v AC = 455 v 452 + 464 + 455 Average Voltage = 3 1371 = 3 = 457 Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v (BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v Maximum deviation is 7 v.

If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly. 2. To determine heater kW at voltages other than those shown in table, use the following formula: Heater kWnew = Heater kW rated x (unit power distribution voltage/rated heater voltage)2 As an example: For a 16 kW heater rated at 240 v with a power distribution voltage of 215 v kW new = 16 kW (215/240)2 kW new = 12.8 kW (rating at 215 v)

Example: Supply voltage is 460-3-60. AB = 452 v BC = 464 v AC = 455 v Average Voltage =
452 + 464 + 455 3
1371 3 = 457 Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v (BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v Maximum deviation is 7 v. Determine percent of voltage imbalance. % Voltage Imbalance = 100 x 7 457 = 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. =
*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, or 480 v. If power distribution voltage to unit varies from rated heater voltage, heater kW will vary accordingly. †Heaters are field installed only. **Fuse or HACR circuit breaker. ††Electrical disconnect cannot be used if electric heater is installed. NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percentage of voltage imbalance. % Voltage Imbalance max voltage deviation from average voltage = 100 x average voltage
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

Example: Supply voltage is 460-3-60. AB = 452 v BC = 464 v AC = 455 v Average Voltage =
452 + 464 + 455 3
1371 3 = 457 Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v (BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v Maximum deviation is 7 v. Determine percent of voltage imbalance. % Voltage Imbalance = 100 x 7 457 = 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. =
*Heater capacity (kW) is based on heater voltage of 208 v, 240 v, or 480 v. If power distribution voltage to unit varies from rated heater voltage, heater kW will vary accordingly. †Heaters are field installed only. **Fuse or HACR circuit breaker. ††Electrical disconnect cannot be used if electric heater is installed. NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percentage of voltage imbalance. % Voltage Imbalance max voltage deviation from average voltage = 100 x average voltage
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

*Two heater packages required to provide kW indicated. NOTES: 1. The rated heater voltage is 240 and 480 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly. 2. To determine heater kW at voltages other than those shown in table, use the following formula: Heater kWnew = Heater kW rated x (unit power distribution voltage/rated heater voltage)2 As an example: For a 16 kW heater rated at 240 v with a power distribution voltage of 215 v kWnew = 16 kW (215/240)2 kWnew = 12.8 kW (rating at 215 v)

*Heaters are field installed only. †Used to determine minimum disconnect size per NEC. **Heater capacity (kW) is based on heater voltage of 208 v, 240 v and 480 v. If power distribution voltage to unit varies from rated heater voltage, heater kW will vary accordingly. ††Fuse or HACR circuit breaker. ***Optional disconnect switch is unavailable. NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance max voltage deviation from average voltage = 100 x average voltage

NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance max voltage deviation from average voltage = 100 x average voltage
Maximum deviation is 7 v. Determine percent of voltage imbalance. 7 % Voltage Imbalance = 100 x 457 = 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

= 457 Determine maximum deviation from average voltage. (AB) 457 – 452 = 5 v (BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. % Voltage Imbalance max voltage deviation from average voltage = 100 x average voltage
Maximum deviation is 7 v. Determine percent of voltage imbalance. 7 % Voltage Imbalance = 100 x 457 = 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%. IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

Determine percent of voltage imbalance. % Voltage Imbalance = 100 x 7 457 = 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. UL, Canada units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. max voltage deviation from average voltage = 100 x average voltage
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

Determine percent of voltage imbalance. % Voltage Imbalance = 100 x 7 457 = 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. UL, Canada units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. max voltage deviation from average voltage = 100 x average voltage
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.

The rated heater voltage is 240 and 480 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly. 2. To determine heater kW at voltages other than those shown in table, use the following formula: Heater kWnew = Heater kW rated x (unit power distribution voltage/rated heater voltage)2 As an example: For a 16 kW heater rated at 240 v with a power distribution voltage of 215 v kWnew = 16 kW (215/240)2 kWnew = 12.8 kW (rating at 215 v)

Determine percent of voltage imbalance. 7 % Voltage Imbalance = 100 x 457 = 1.53% This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
NOTES: 1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. UL, Canada units may be fuse or circuit breaker. 2. Unbalanced 3-Phase Supply Voltage Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent of voltage imbalance. max voltage deviation from average voltage = 100 x average voltage
IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.
