I need to add a 220/240-volt (single-phase) circuit to my shop for a bandsaw. Does a typical circuit breaker allow for a circuit draw above the breaker’s rated output during the first few moments a motor is starting? The bandsaw’s motor is listed as 220volt 15.3 amp. (Supposed to be 3 hp but its European made so who really knows) If I have an electrician (my wife won’t let me near the box) wire a 20 amp 2 pole circuit breaker (type MP) to the Crouse/Hinds load center (100amp service at the panel) will the breaker blow during startup. My understand was that motors often draw 2-3 times their amp rating at startup. At the same time, I don’t want to put a 50amp breaker in if all I needed was 20-amp service to this machine. It could take a while for a 15 amp motor to draw enough to blow a 50 amp circuit breaker that large and seems to sort of negate any benefit of having a breaker in the first place.
The local code calls for a GFCI breaker in the unfinished basement. (It is damp down there at times) JCrocker
