Hi-
I'm planning on adding a Suntouch to my pool to replace the intermatics I have and automate the valve on my solar panels. The main circuit feeding my pools subpanel is 40amp. This is shared by my furnace, which is gas and therefore probably uses a small fraction of that 40amp. There's 240v going out to my pool panel (iirc the main and booster pump are hooked up for 240).
My current subpanel has three breakers; 1 for main pump (1hp), 1 for booster pump (3/4hp), 1 for 120v lights (gfci).
QUESTION.... When I install the Suntouch, I understand that I need to still have gfci. The recommendation in the manual is to go from the relays to a subpanel then to the equipment. To keep it simple I would like to have 1 main GFCI breaker. Seems to me that I can one of two things; install a GFCI in my main/house panel and nowhere else in the system, OR, install a GFCI in the subpanel downstream from the Suntouch. The first option is cheaper. Is one better than the other? With the 2nd option I won't be able to have just one gfci breaker, I would have to get one for each pump and the pool light. ?
A 3rd option, mentioned in this link (wiring-question-upgrading-to-a-suntouch-controller-t42815.html?hilit=suntouch) would be to have main power come into subpanel (1 main gfci breaker) THEN power to the Suntouch and the pumps from there.
Thanks,
Kevin
