Pool Bonding

Jimmy7 said:
I’m going to try a NEV test today, but I have a some of questions.
1. Does it matter how deep my reference point is? Could I use a long screwdriver? If so, just strip the conductor and wrap it around? 3 or 4 inches, wrap around but ensure resistance low reference point 4 ft atleast away existing gtounds

2. There are pavers for a pool deck here. Just wet the paver and look for a reading?Better conductive mat if available or bonded metal surface

4. What would you recommend I use for a conductor for my test? Does it matter the size, and is solid or stranded better?Insulated stranded wire standard meter leads ok as voltage measurements, not current measement

Thank you

Use ppe

On question 2. With the pavers I think there is a copper grid underneath. Would I get a reading if the pavers were wet, or how would I check the areas with the pavers (No concrete just pavers in this area). What if I can’t get to the copper grid underneath?

You get readings in paver wet, but may not consistent. use metal surface like on pool pump bond to copper grid if you not get to copper grid.
Possible you also measure surface water to water potential differences

Just measure to a wet paver. You need to verify that the pavers are bonded.

Yes a screwdriver or section of ground rod or rebar is fine. That temporary grounding electrode should be in "remote earth". Remote earth is typically defined as being 50' away from any other grounding electrode or any bonded metal underground structure. Most common underground metal would be a metal underground water pipe.
I know that in some cases you can't get the temporary grounding electrode that far away, but get it as far away as possible

You really need to measure the pavers themselves. You have to know that they are actually bonded so that they will be at the same potential as everything else associated with the pool
And, yes you do need to measure the water itself.
You have to measure everything that is required to be bonded.
