Reinstalling Hayward 1.25 hp - all done except WIRING QUESTION: 2 black wires,no white (+ green ground); how to tell which black wire is the supply?

Jack,

You really can't go by just the wire color..

In 'general' two black wires would mean that your voltage is 240 volts.. In which case it does not matter which wire goes to which Hot input connection.

Do you know if your supply voltage is for 240 or 120???

Thanks,

Jim R.
