MCB rating for half HP Motor

04/25/2008 9:42 AM

What MCB should I use for a half HP single phase motor knowing the fact that a motor draws more current when it starts.

Same old story... WHERE ARE YOU?? or in your case what Mains voltage do you use? This will have a major impact on the size of circuit breaker you need. We can't even begin to guess without that information.

Much Thanks

Bill
