So after a few months of living in this new house I'm starting to find some questionable electrical wiring, the pool included. I've got one cable going back to my breaker box to a 30 amp breaker. 2 wire cable (with unshielded ground), no neutral. My concern is that my 12v pool light and convenience outlets (and shed light) are all hung off of this 220 circuit my 2 pumps run on. I called an electrician today who said I could put white tape on the ground wire, use it as a neutral and drive a ground rod in and use that as the ground. I'm not so sure that's right, which is why I've posted this thread. I want to replace the 30 amp breaker with a GFI breaker, and also protect the outlets with GFI, either through that breaker or just a GFI outlet.
far left switch is the pool light, the pvc feeds those 110 outlets. the other 2 switches are for the main and booster pumps.
bonus sketchy junction under the diving board. This should really be in a box not under the diving board, shouldn't it?
