YORK INTERNATIONAL
NOTES:
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 Factory Mounted Control Transformer is provided, add the following to the
system MCA values in the Tables: -17, add 10 amps; -28, add 9 amps; -40, add 6 amps; -46, add 5 amps; -58, add 4 amps.
2. Minimum fuse size is based on 150% 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 U.L. Standard 1995, Section 1995, Section 36.1. It is not recommended in all applications where brown outs,
frequent starting and stopping of the unit and/or operation at ambient temperatures in excess of 95°F is anticipated.
3. Maximum fuse size is based on 225% 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 440-12A1.
4. The recommended disconnect switch is based on 115% of the rated load amps for all the loads included in the circuit, per U.L. 1995, Fig. 36.2.
5. HACR-Type circuit breakers are UL-listed circuit breakers that have been found suitable for use with heating, air conditioning and refrigeration
equipment comprising multimotor or combination loads and are marked Listed HACR-Type, refer to N.E.C. Article 440-21. Maximum HACR
circuit breaker rating is based on 225% 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 UL 1995, Fig. 36.2. Canadian and international models may not require HACR-Type circuit breakers.
6. 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) preceding the wire range indicates the number of termination points available per phase of the wire range specified. The (1-2), (1-
3), or (1-4) preceding 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 wire 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 on the National Electric
Code and using copper connectors only. Field wiring must also comply with local codes.
7. A ground lug is provided for each compressor 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 - #2/0.
8. The supplied disconnect is a Disconnection Means as defined in N.E.C. Article 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.
9. All unit compressors have a part winding electrical configuration such that the indicated Locked Rotor Amps are Part Wind Locked Rotor Amps.
