my pump has a 20amp, 15ft long cord with a large GFI attached near the plug end,this plugs directly into another GFI on my outdoor service post.
This year I would like to get away from running my pump 24/7 unless I run my heater which will shut down" lock-up" if it notices no water flow.
I purchased a mechanical outdoor metal timer,encased it into a plastic weather proof large box housing for extra measure,drilled 2 holes on bottom with weather proof cord cable restraints,wired male connector to timer which will plug into service power post 20amp GFI.
Then also wired female plug to timer which I intended to plug the original power cord from pump into that.Problem I have, I noticed when ever I unplug the cord from the outlet, the factory in line GFI trips and I have to push re set button.So my timer idea I thought would be great,is not going to make anything any easier as I would have to continually re set the breaker after the time shuts off the pump and re starts a few hours later.
I like the in line breaker on the Doughboy pump and don't know if I should eliminate it and just count on my GFI of the receptical alone?
