Continously - no, this is for a table saw in my personal shop. I picked the #8 wire because it is an approx. 100 ft. run. I was think that the breaker was either to be 20 or 30. As you may have noticed, the answers are over quite a range. Thanks!NEC T430.248 says 17 amps. Will this motor be used over 3 hours at a time?
If this motour start up unloaded then 20 amp breaker will handle very nice but if air compressour please look at the nameplate to verify if it did show the actual HP rating or marked SPL one of the two.What is the appropriate breaker size for 1Ph, 240v, 3hp motor on #8 wire slightly over 100 ft. from the panel?
