STANDARD COMPRESSOR POWER SUPPLIES
(Each Compressor System Power Supply Individually Protected with Field Supplied Branch Circuit Protection)
NOTES for Electrical Data :
1. Minimum circuit ampacity (MCA) is based on 125% of the rated load amps for the largest motor plus 100% of the rated load amps for all other
loads included in the circuit, per N.E.C. Article 430-24. If a Factory Mounted Control Transformer is provided, add the following to the system
#1 MCA values in the YCAS Tables: -17, add 10 amps; -28, add 9 amps; -40, add 5 amps; -46, add 4 amps; -58, add 3 amps.
2. The recommended disconnect switch is based on a minimum of 115% of the summation rated load amps of all the loads included in the
circuit, per N.E.C. 440-12A1.
3. Minimum fuse size is based on 150% of the largest motor RLA plus 100% of the remaining RLA’s (U.L. Standard 1995, Section 36.1).
4. Maximum dual element fuse size is based on 225% maximum plus 100% of the rated load amps for all other loads included in the circuit, per
N.E.C. 440-22.
5. Minimum circuit breaker is 150% maximum plus 100% of rated load amps included in the circuit, per circuit per U.L. 1995 Fig. 36.2.
6. Maximum circuit breaker is based on 225% maximum plus 100% of the rated load amps for all loads included in the circuit, per circuit, per
U.L. 1995 Fig. 36.2.
7. The Incoming Wire Range is the minimum and maximum wire size that can be accommodated by unit wiring lugs. The (1), (2), (3) or (4)
preceeding the wire range indicates the number of termination points or lugs which are available per phase. The (1-2), (1-3) or (1-4)
preceeding the wire range indicates that a single multi-termination lug is available per phase that can accept from two (1-2) to four (1-4) wires
of the wire range specified “(1) #1-600MCM OR (2) #1-250MCM” indicates that a single lug is supplied and it will accept a single wire up to
600MCM or 2 wires up to 250MCM. Actual wired size and number of wires per phase must be determined based on ampacity and job
requirements using N.E.C. wire sizing information. The above recommendations are based onthe National Electrical Code and using copper
connectors only. FIeld wiring must also comply with local codes.
8. A ground lug is provided from each compr. system to accommodate field grounding conductor per N.E.C. Article 250-54. A control circuit
grounding lug is also supplied. Incoming ground wire range is #6-350MCM.
9. The supplied disconnect is a “Disconnecting Means” as defined in N.E.C. 100.B, and is intended for isolating the unit from the available
power supply to perform maintenance and troubleshooting. This disconnect is not intended to be a Load Break Device.
