*Used to determine minimum disconnect per NEC. †Fuse or HACR circuit breaker per NEC.

**Fuse only.

††Compressor no. 1 is shown in table.

208/230-3-60: Compressor no. 2 RLA is 14.1 amps and LRA is 105 amps.

460-3-60: Compressor no. 2 RLA is 7.1 amps and LRA is 55 amps.

575-3-60: Compressor no. 2 RLA is 6.4 amps and LRA is 40 amps.

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.

Determine percent of voltage imbalance.

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 558FPX091000 unit with MCA = 40.1 and MOCP = 45, with CRPWREXH030A01 power exhaust.

MCA New = 40.1 amps + 1.6 amps = 41.7 amps

If the new MCA does not exceed the published MOCP, then MOCP would not change. The MOCP in this example is 45 amps, the MCA New is below 45, 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.

NOTE: The following equation converts kW of heat energy to Btuh: kW x 3.412 = Btuh.

EXAMPLE: 32.0 kW (at 240 v) heater on 208 v

=24.0 kW capacity at 208 v

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.
