Question:
Greetings,
Is two poles GFCI circuit interrupter required for a 240volt Pool Heater?
Thank you,
A
Answer:
Hello Dick,
Thanks for the question. The answer is generally no. However, be advised that if the equipment were in close proximity to the inside walls of the pooL, GFCI requirements could apply. Also, there is a requirement for GFCI protection on the circuit, supplying a gas-fired water heater for a permanently installed pool that operates above the low-voltage contact limit. See 680.28.
