2 Questions: #1- I recently purchased a heat pump to heat my inground pool. The pump requires a 220V 50Amp power supply. I have run that source from my main panel to a disconnect that contains a 50Amp GFCI Breaker in it. This is commonly used for Jacuzzi's. My question is did I need to a neutral feed along with my 2 hots and ground in order for the GFCI Breaker in the disconnect to work properly? The unit I am wiring does not need the neutral so I did not run it. Now I am wondering if I should have for the GFCI Breaker???
#2 - I need to bond this new piece of equipment and was going to bond onto the bonding lug of existing pool pump. This already has 1 piece of #10 solid copper wire in it from the frame of the pool. My plan was to put another #10 solid copper wire in the lug and then the other end in the bonding lug of the heat pump. Is this be a sufficient and safe bond?
Any thoughts and comments would be appreciated.
