Intermatic Pool Timer Wiring

[mas985]

Possibly if the voltage drop was significant. But if the wire size is at least 14 gauge, that is sufficient for that pump.

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.

Thanks for the info.

@Mark, your signature says you have a .5hp 2 speed pump. What make/model is it? Or did you put it together from individual components?

[mas985]

I put it together with a 1/2 HP Northstar wet end and a 2 speed motor.

Sorry about delayed response. I was out of town. I checked the pump and it is wired for 120V. The pump still works. It takes about 1/2 HR. before it gets hot enough to shut off when it runs during the early morning hours. I will have an electrician look instead of a pool guy but I really don't think the wiring is the problem. I took a picture of the pump wiring.

I forgot to correct the 120V to 115V. I found the manufacturer date for the pump. It is 06/18/2005. I wish I found out sooner. This pump's 9th birthday is getting close and the overheating problem is likely due to its age. I might as well use it until it quits. The suction and expulsion are really strong and it keeps my pool pretty clean. I am having a Home Performance review next week and that could include a recommendation on replacing my pool pump. I would get a rebate or low interest financing through SMUD. I will close this thread since we now know the Intermatic Timer was working correctly and the pump is old and needs to be replaced with an energy efficient dual speed pump. To those of you who responded, thank you for taking the time to help me out. I have learned a lot and am now too scared to mess with the electrical stuff. You probably saved my life.

Glad things are working out for you!
