On a heat pump do you add 1.25 to the minimum circuit amps that the manufactures plate states, or is that already factored in to the MCA
TIA
 
You may size your conductor using the MCA number (no multiplier)

Size your conductor based MCA (Minimum Circuit Ampacity) and size your OPD base on the MCB (Maximum Circuit Breaker) or MFS (Maximum Fuse Size)required by the nameplate!
