The installer only used three wires. Looks like two live black wires and a green ground. I was told I need a additional neutral wire to bring things into code. Woudl that be correct? Thanks for any input
Is it code when installing a pool heat pump to be using three or four wires?
I take it the pump in question is 220? You say both wires are black,or live? then yes you need a neutral back to the breaker box connected to the neutral ground buss. The green only grounds all box's to ground, that doesn't ground the electrical unit to earth ground. Call the electrician that installed it and tell him to do it right.
Reply:It is 4 wire for 240 volt installation by code in some states now
Reply:Should be 4 wire system G.F.C.I. protected
Reply:Yes I believe that would be correct it should be run through a ground fault interrupter circuit also.
This would protect any persons in the tub from electrical shock in the event something would go wrong with the pump motor.
