I installed the hayward hp50ta pool heat pump. I am using a double pole breaker. I used 10-3 w/ ground for 30 amp 220 volt service. I hooked up the red and black wires to the breaker and the white and bare wire to the ground bar in the panel. I then wired the red wire to L1 at the heat pump and the black wire to L2 at the heat pump. The only other connection it shows in the diagram is a ground connection so I hooked up the white wire and the bare wire to that. When I turned on the breaker, it immediately turned itself back off. I can't figure out what I did wrong. I have 110 on both the red and black wires to the ground and I also have 220 between the red and black wires together. Need help? Steve Smith
