Hi everyone...
On a walk in cooler compressor, the compressor says a minimum ampacity of 18A. I have been told it is the minimum "wire" size and not the FLA which requires 125% sized wire....seems the same as i was told for some rooftop units, that is that they are for wire sizing, not calculating. is there a rule of thumb when to apply wire sizing other than going big and size the wire to 125% as one suggested, which can be a costly pain trying to make connections with #10 copper. I'd love to hear why they already do the calculations in some cases and not others.
Thanks again!
