Notes for Electrical Data
1.
Unit wire size ampacity (MCA) is equal to 125% of the largest compressor-motor RLA
plus 100% of RLA of all other loads in the circuit.
2.
The control transformer is furnished and no separate 115V power supply is required.
3.
If a separate 115V power supply is used for the control circuit, then the wire sizing
amps is 10 amps for all unit sizes.
4.
Recommended power lead wire sizes for three conductors per conduit are based on
100% conductor ampacity in accordance with NEC. Voltage drop has not been
included. Therefore, it is recommended that power leads be kept short. All terminal
block connections must be made with copper wire.
5.
“Recommended Fuse Sizes” are selected at approximately 175% of the largest
compressor RLA, plus 100% of the RLA of all other loads in the circuit.
6.
“Maximum Fuse or breaker size” is selected at approximately 225% of the largest
compressor RLA, plus 100% of all other loads in the circuit.
7.
The recommended power lead wire sizes are based on an ambient temperature of 86°F
(30°C). Ampacity correction factors must be applied for other ambient temperatures.
Refer to the National Electrical Code Handbook.
8.
Units must be electrically grounded according to national and local electrical codes.
Voltage Limitations:
Within
±
10 percent of nameplate rating
Important
: Voltage unbalance not to exceed 2% with a resultant current unbalance of 6 to
10 times the voltage unbalance per NEMA MG-1, 1998 Standard. This is an important
restriction that must be adhered to.
Notes for “Compressor and Condenser Fan Amp Draw”:
1.
Compressor RLA values are for wiring sizing purposes only but may not reflect normal
operating current draw at rated capacity.
2.
Fan motor FLA values are approximate fan motor amp values at rated voltage.
Notes for “Field Wiring Data”
1.
Requires a single disconnect to supply electrical power to the unit. This power supply
must either be fused or use a circuit breaker.
2.
All field wiring to unit power block or optional non-fused disconnect switch must be
copper.
3.
All field wire size values given in table apply to 75°C rated wire per NEC.
