I went to a customers house he feels a tingle(electrical) getting out of pool he has a aluminum border all around the edge of his in ground pool when he is in the water leaning on this he can feel it. I wasnt able to pick it up with a meter but can try larger conductor in water. I turned off main breakers and he could still feel it. I an thinking problem could be with underground service miss utility is sched to mark.The bond wire I can see looks fine.He says he noticed this last year when chlorinator was installed I think this is coincedence. I was ther for other work but the tingle really bothers me.If there is no power to pool equipment it doesnt sound like bonding issue right?
 
I would check for current on the utility water piping with the power off for starters.

Check current on the neutral, and neutral ground bond with the power off.

Check for zero sequence current with the power on and off.

Call the local utility service rep (Dominion Power?) good luck with this one. Dominion has an I could care less attitude.


As hot as it is I would avoid the pool in the short term until you figure this out.

There's a clue right there. (Bold) Is the clorinator powered or just a water tie-in? If it's powered that is the first thing I would disconnect and see if the voltage goes away.

Otherwise it is highly likely to be a POCO issue.

OP said he turned off main breaker and the customer could still feel the tingle. :)

If the problem is the worst during really hot weather, it is probably voltage drop from the utility primary neutral. Also could be a secondary fault that is not tripping a breaker due to high impedance in the ground fault path. Something is not bonded correctly if either of these are the cause. Take voltage measurements between the contact points, and also take voltage readings between each contact point and remote earth. What were the actual readings? If you are measuring less than 1 Volt, and the customer still says he feels a tingle, I would be suspicious of the customer...:confused:
