Should my retaining wall with rebar be bonded to pool grid?
 
Hey guys I have a retaining wall about 15 feet from the edge or the pool. Its all concrete pass between wall and pool. The retaining wall is made of faced cinderblock and rock. The cinderblock part is filled with concreate. This part of the retaining wall has rebar in the base for added support. The pool equipment is about two feet away. The pool equipment is properly bonded to the pools bonding grid. However should the rebar in the wall have been bonded to the grid or is the distance far enough away?

Been reading about this whole bonding thing and figured i would ask

Thanks in advance

No. Not required.

Measure the AC voltage between the pool concrete and the retaining wall concrete. Concrete is reasonably conductive.

If it's 0.00 vac then connecting the two together won't make any difference.

If it's more than 1 volt some people with wet skin touching both may sometimes feel a tingle, or worse.

This should be interesting.

Use any multimeter on the AC volts scale to measure the voltage between the pool concrete and the retaining wall concrete that is 2' away.

The bonding is to equalize the potential between two conductive surfaces you could be touching at the same time.

It's 15 ft away, how the funk would you touch the water and the wall at the same time? :whistling2:

"The pool equipment is about two feet away." ?

Two feet away from what?

EDIT - and what does that matter?

I should have asked the OP that question.
Still, I'd like to know what kind of potential difference there is just for my general knowledge. At 15' he'll need to use an extension cord as a test lead.

I don't get where you are going with it, who cares if there is a voltage potential, you're not going to be able to reach 15' from the pool water to the retainment wall.

They are huge, grounded, conductive masses. The measurement will help me decide what ground voltage differences are plausible and what are off-the-wall.
I hope.

My motives for being on this forum are different than yours. :whistling2:
This kind of measuring, calculating and rechecking are what got me illegally forced out of the corrupt federal agency that I once worked for.
I guess I haven't learned my lesson. :(

:thumbsup:

You're missing so much general knowledge on stray voltage though, not saying you'll never grasp it, but at first look, its going to be way over your head, let me post you a link so you can indulge yourself in.... hang a second....

Watch the whole video, very good watch..... might be a little hard to grasp.
