Bonding a Fiberglass Pool (Ontario) - Opinion From My Electrician

Hey all,

I've been inching towards having a fiberglass pool installed in Southern Ontario. I've found one PB who I like and who has good references. He didn't feel that the pool would need to be bonded as there are no rails/metal parts/etc. But he also said bonding is more of an electrician function and gave me the phone number of the electrician who he works with on his pool installs.

I sent snippets of articles i found online regarding bonding of fiberglass pools, and his response is posted below. Given that I know nothing about pools, bonding and electricity, I'm sharing the electricians response back, and hoping you guys can provide your thoughts/feedback? TIA!

I’ve read through them all (referring to the links I sent him). I think the point they’re trying to make is that the water could carry a charge that differs from earth. I just disagree with how they try to explain that

For the water to be charged and not ground out you would have to have zero connection to ground. The link from Seabreeze explains that. But we do ground out the pump, salter, heater, rebar and anything metal. Water is in direct contact with the pump and heater. So unless you had all plastic parts I’m certain the water couldn’t carry a charge

I guess if you look at it like that, we are essentially grounding a fiber pool. Just not the same way as a metal. With a metal pool we physically ground the pool wall. Not because the water could be charged, but because the pool wall could be charged. But that’s impossible with a fiber pool. It’s non-conductive. Either way, the water is already at a potential equal to the equipment and earth, ideally 0 volts

That’s my take on it anyways. As I mentioned, I think if it would make you feel better, maybe adding the skimmer bonding lug is something we should consider for your application. I don’t think it would cost very much for the peace of mind

For what it's worth, you can see how they did my pool below. A ground was routed all around the pool in contact with the rebar that was anchored to the pool. The rebar anchoring concept was to help add stability to the concrete decking, coping, and the edge of the pool. In addition I have a ground screw at the base of my pump.

Thanks all for the feedback.

Is bonding something that is 'testable'? I'm quite comfortable with the PB and electrician, but bonding fiberglass pools isnt something they do. They will do it, but given that they don't have experience doing so, I was wondering if it is something that the electrical inspector can check, or if its something that i can check/test afterwards (eg. use a meter to test water voltage periodically).

Thoughts?

Tom,

Does your pool have a light? If so, I was under the impression that is what bonded the water to the bonding loop in the deck? :scratch:

Hey Jim,
Yes! We will have lights, but apparently the lights we are going with (Treo LED Pool Light - Official S.R. Smith Products) is in a plastic housing and therefore does not requisite bonding).

This whole ‘bonding’ uncertainty is the only thing holding me back from signing a contract and going with it all:/

As such, any additional thoughts/feedbacks and definitely appreciated.

Thanks!

Tom

My light is in a plastic housing yet it still has a bonding lug... But it is a full size non-LED bulb...

I can see where your light do not... sigh!!

Your electrical contractor is on the right path. His bonding/grounding nomenclature is a tad off, semantics.

Im surprised he would put this “opinion” in writing.
Maybe I’m just a hardened New Englander.

Get the water bonded & everything else your jurisdiction requires.

Is this up to your electrician? If so, I am very surprised especially in Canada. Bonding here is not an option. Also it is not the same as a grounding. Incorrect bonding is the #1 reason for pool inspection failures. My inspector told me a few years ago in my area a 12 year old girl was electrocuted when lightening struck in the area and she was standing on the deck of an improperly bonded pool near a piece of floating rebar.
