Hi have a chiller rated 208V, 3P, MCA: 46.1, MOPD: 80, RLA: 30. Its been awhile for sizing motor branch ckts but any idea how to size the ckt. & OCPD?
Correct me if I am wrong but last I remember based on the nameplate info conductors can be #6 with 60A circuit breaker?
MCA = minimum current ampacity
OCPD = maximum over current protection device
Where in the NEC doesnt reference sizing ckts per nameplate?
thanks in advance
