So if I understand how wire size works, the 12 AWG is okay because it is bigger than 14 AWG? The distance from pump to timer is about 6 ft. I haven't had a chance to test the terminals with a multi-meter but I don't think there is a problem with the voltage. I will visibly check the wiring on the pump to see if it is wired correctly. My handyman isn't available to help me, so I will have to do it myself.
