NOTES:
1. Minimum Circuit Ampacity (MCA) is based on 125% of the rated load amps for the largest motor plus 100% of the loaded amps for all other loadsincluded 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 MCAvalues 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 36.2). It is notrecommended in applications where brown-outs, frequent starting and stopping of the unit, and/or operation at ambient temperatures in excessof 95°F is anticipated.
HACR = Heating, Air Conditioning and Refrigeration
3. Maximum dual element fuse 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 accomodaed by unit wiring lugs. The (1), (2), (3), or (4) indicatedthe number of termination points which are available per phase. Actual wire size and number of wires per phase must be determined based onampacity and job requirements using N.E.C. wire sixing information. The above recommendations are based on the National Electric Code andusing copper connectors only. Field wiring must also comply with local codes.
7. A ground lug is provided for each compressor system to accomodate field grounding conductor per N.E.C. Article 250-54. A control circuitgrounding lug is also supplied. Incoming ground wire range is #6-#2/0 (50-90 Tons) or #6 - 350 MCM (95 - 220 Tons).
