Hi,
I bidding a job to update some construction around an older (1960s-era?) in-ground pool in Southern California. Among other things, the job includes replacing the pool pump and building a privacy trestle so the equipment is not so visible (but leaving the required access to the shut-offs).
Looking at the pool deck, though, I do not see any access to the embedded rebar - and I am not sure if a pool built in the 1960s even has an equipotential grid, as required by the more recent versions of the NEC. The current pool pump has a GROUNDED connection to the timer/disconnect panel, but the bonding lug is not connected on the pump, filter, or heater.
Two questions:
1. By simply replacing the pool pump, is there a requirement to bring all of the pool systems forward in compliance with NEC 680.26 (e.g. 9in square contact with the water, all metal needs to be bonded, dig up pool deck and install #8 AWG around the pool)?
2. If there is no external access to the pool rebar, how does the code recommend meeting the intent of equipotential bonding? (N.B. I have read about connecting to the electrical system neutral, but this seems unusual...)
Thanx in advance for the forum's counsel...and if this specific topic has already been addressed in a previous thread for OLDER POOLS, please forward me a link and I apologize for not doing enough homework.
