Hi all,
Running under the 2017 Code cycle.
I've an elevator that was just VE'd, changing the electrical details. Called the elevator designer and verified that these numbers are correct.
NEC's 620.61(D) references 430.52(B), which states "The motor branch-circuit short-circuit and ground-fault protective device shall be capable of carrying the starting current of the motor."
My question is what size breaker and conductor amperage is required by NEC directly upstream of the elevator controller?
My first reaction is 300A breaker and 159A wire. (highlight for my thoughts)
