Stray Voltage in Fiberglass Pool


Can anyone suggest a interim solution while my power company here in NJ addresses an imbalance of the Neutral connection on my street. My fiberglass pool gets anywhere from 2 - 7 volts both on the metal handrail and surrounding concrete. I have no rebar and there's no metal anywhere around the pool. When the pool was installed in early 2006, a grid system was not required (it is today). When the Neutral wires are pulled from my home, the problem goes away....the Power confirms an imbalance of their neutral's but can not tell me when it will be resolved. Nobody else is complaining since there pool not fiberglass.......

Check out this thread.

pool "current"

I don't see that the problem was solved but hopefully it was.

I don't know of any steps you can take to mitigate a power company problem. Bonding the metal parts and even the water itself, back to your electric service panel grounding bus might solve the problem. Where is the nearest electric circuit? Pump/filter? Are you measuring the 2 to 7 volts between the water and the handrail and concrete?

Tell the power company you have notified your attorney of the problem for liability purposes. That will get them moving.

One of my neighbors called the power company to light a fire under them like that. He told them he had a life safety hazard and threatened to sue them. They sent a lineman to pull the meter and disconnect his service until they could get to fixing the problem. That way they wouldn't be liable for anyone getting injured or killed.

Some times threats can backfire.

ok here's one...but I'd like to hear a few opinions before doing anything.

I'd suggest burying a good size copper conductor around the pool at about 24' deep and about 3' from the pool edge.

The idea comes from substation earth and fence grounding. I think that if you install a grid to provide an alternate low impedance path it might work.
