New 2020 Pool Re-inspection 680.4

[jusme123]

If the NEC is now allowing periodic inspections (680.4), why not require the equipotential ground wire to START at the pool pump, circle the entire diameter of the pool connecting all required pool components, and RETURN back within 1’of the pool pump. This would allow easier/better periodic testing of the pools equipotential grid around the pool by confirming no breaks in the wire.

You would need to check several points. Not all pools have a single conductor/wire encircling the pool. They use a grid of rebar tied together with the single conductor only tied into it. If you ran the single wire to/from the grid and just checked it for continuity, there might be areas that has come loose from the grid but still are intact. This would give you a false assumption that the grid is intact and complete.

Same could be said with above ground pool. The copper wire could be broke at the first connection point to the pool itself and use the metal pool base for connectivity to the other 3 connection points. By a ground loop that starts at the pump and ends 1’ near the pump the loop can be verified, along with the other required points
