I have a sub panel next to my pad, with a 240V breaker feeding my pump (through a timer). It just occurred to me that the pump is not GFCI protected. I did a bit of reading here, and it appears that it was built to code, but the code has since changed, and it would not be compliant now. Others here have stated that if feeding a pump directly (no outlets), GFCI is not necessary. It seems to me, however, that a fault in the pump could electrify the pool. I'm not really anxious to spend $110 on a GFCI breaker, but I'm even less anxious to get electrocuted by my pool. So is a GFCI breaker necessary? If not, why not?
