I have a 19 amp 120V load on a pool pump and salt generator.

I am running the load through a 30 amp rated time clock.

My problem is that SquareD Homeline does not make either a 25 or 30 amp single pole GFCI breaker.

I've looked at the cut sheet for the 2 pole GFCI but it does not show wiring for single pole use.

Anyone here have experience using a 2 pole as a 1 pole?

Will an AHJ accept the use if it's not designed for it?
 
Straight 120v


Salt chlorinater has to operate with pump. It came wired for 220V but is convertible.

Heater is convertible as well.

120V pump kicks the amperage up to 19A.

Most pump motors are dual voltage. Check and see if you can change it to 230V.
Or just use the 2-pole as a SP.
 
If you can't wire both for 240v, but you can make it a MWBC (120/240), put the pump on one circuit and the salt unit on the other. Then you can use a smaller 2p GFCI.
 
Are you using a pentair panel? If so I’d use Siemens breakers in it. Siemens gfci breakers are the only ones I’ve found that do not have tripping issues with pool pumps. Normally I’d use CH or BR but with pools I use the Siemens gfci breakers. Also I’d just put a 20 ampere gfci on the pump. I’ve not had many inspectors tell me I have to up size it because it can run constantly. Just make sure your wire size can handle the upsizing. It’s really only an issue if you end up with nuisance tripping.
