NOTES: (for Electrical Data on pages 88-93)
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 440.33. If the optional Factory-mounted Control Transformer is provided, add the
following MCA values to the electrical tables for the system providing power to the transformer: -50, add 5 amps;
2. The minimum recommended disconnect switch is based on 115% of the rated load amps for all loads included in the circuit, per N.E.C.
Article 440.
3. Minimum fuse size is based upon 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 to avoid nuisance trips at start-up due to lock rotor amps. 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 35ºC (95ºF) is anticipated.
4. Maximum fuse size is based upon 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 440.22.
5. Circuit breakers supplied by third party vendors must be certified by local electrical standards. Maximum 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.
6. The "INCOMING WIRE RANGE" is the minimum and maximum wire size that can be accommodated by the unit wiring lugs. The (2)
preceding the wire range indicates the number of termination points available per phase of the wire range specified. Actual wire size
and number of wires per phase must be determined based on the National Electrical Code, using copper connectors only. Field wiring
must also comply with local codes.
7. A ground lug is provided for each compressor system to accommodate a field grounding conductor per N.E.C. Table 250.122. A control
circuit grounding lug is also supplied.
8. The supplied disconnect is a "Disconnecting Means" as defined in the N.E.C. 100.I, and is intended for isolating the unit for the available
power supply to perform maintenance and troubleshooting. This disconnect is not intended to be a Load Break Device.
9. Field Wiring by others which complies to the National Electrical Code & Local Codes.
