NOTES for Electrical Data pages 34 - 39:
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 YCA Tables: -17, add 10 amps; -28, add 9 amps; -46, add 4 amps; -58, add 3 amps.
2. Minimum fuse size is based on 150% of the largest motor RLA plus 100% of the remaining RLAs (U.L. Standard 1995, Section 36.1). It is not
recommended in 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 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.
4. 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.
5. Maximum HACR 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.
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)
indicated the number of termination points which are available per phase. 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 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 - #2/0 (50 - 90 Tons) or #6 - 350 MCM (95 - 230 Tons).
