Sizing Compressor Feeders

[garyfitzgerald]

Specs for a large chiller are MCA=382, MOCP=600. Do I size the feeders to the MCA or the MOCP?

The former, as long as the unit contains its own overload protection.

I agree with Larry, you certainly can size the conductors per MCA.

However you may want to consider voltage drop at start up.
