I am rewiring for electrical service to our pool area, upgrading from 120 volts to 240 volts. I am also intending to add a safety switch disconnect (double pole NEMA type 3R) right by the pump/filter equipment. (The previous 120 volt/single speed pump system had no outside disconnect, did not have a GFI breaker at the panel, etc).

I think that the disconnect cabinet should be bonded along with other equipment and pool-side fixtures, but wanted to check on this issue. It's a bit tricky tracking this information down online. If the safety disconnect doesn't have a specific bonding lug, I should be able to tie in with the grounding terminal on the body - is that common practice?

If the disconnect does not have a bonding lug then leave it as is.

Do NOT connect bonding to grounds in the USA.
