Hello experts, I've seen a few questions on pools lately, but I could not find mine.
An pool guy recently replaced an 9.4 amp 240V pool pump. the installer noted that the switch for the switch only cut power to one of the hot lines (aka it was only single pole), so I replaced that with a double pole switch. When I did that I noted that the system was connected via a pair of 14AWG THHN along with a ground to the main Square D QO panel with a 30 (!!) amp 2P breaker.
The 30A breaker was obviously wrong (and dangerous), so I planned on downgrading the breaker to 15 amps.
Now I also see in the 2020 NEC, that 680.21D says replacing a pump now requires upgrading it to GFCI protection.
I wholly agree with the safety aspect and would like to do this properly, but I am unclear on how would I do this with a pump that is hardwired 240V with no neutral.
Don't GFCI breakers require a neutral connection (the pigtail?) or are there 240V GFCI downstream devices available?
