Which code cycle were they added?
Nevermind i see it in NEC 2020. Below is script
2020 Code Language:
680.21(C) GFCI Protection. Outlets supplying all pool motors on branch circuits rated 150 volts or less to ground and 60 amperes or less, single- or 3-phase, shall be provided with Class A ground-fault circuit-interrupter protection.
Exception: Listed low-voltage motors not requiring grounding, with ratings not exceeding the low-voltage contact limit that are supplied by listed transformers or power supplies that comply with 680.23(A)(2), shall be permitted to be installed without GFCI protection.
N 680.21(D) Pool Pump Motor Replacement. Where a pool pump motor in 680.21(C) is replaced for maintenance or repair, the replacement pump motor shall be provided with ground-fault circuit-interrupter protection.
Just curious how does one determine branch circuit rating for pump in op#1 should we have NEC 2020? The pump is being fed from 150A breaker at 208V three phase
