Just some background here... I finally talked my uncle this year into installing a SWG. He is loving it so far--very easy maintenance. So over the weekend I go over and check on to see how he is doing. Pool is looking great. We are talking there and he says he has been feeling like a small "Buzz" from whenever he goes to get out of the pool using the stainless hand rail. I check it out for myself --and sure enough you could feel small trickle of current around my hand up into my arm. So I went home and grabbed my meter and started checking everything. We killed all the circuits that had anything to do with the pool and surrounding area--still could feel the small buzz. I checked with my fluke meter from the hand rail to the water and sure enough-- I was reading about .800 volts DC on the meter. I done more checking around the pump area and everything-- really was scratching my head at that point. Only thing I could come up with --Is that the hand rail had lost its bond to rest of the grid. So for a temp fix-- I used a stainless worm clamp and piece of Nichrome wire with a stainless bolt hanging in the water to make the handrail the same potential.. My uncle is getting the pool builder to come back and check over everything.. Just wondering if anyone had experienced this with a fiberglass pool.. any thoughts / comments ??
