The cord is a 12AWG cord unless they mis-stamped it. The outside receptacle circuit goes to the GFCI in the garage. Nothing else is plugged into it. My other pump was bought with the pool back in 2001. I believe it was the motor. When I plugged it in, it would just have an electrical hum. The night before it started just humming, it was making a really loud pumping noise that I could hear from inside the house. The noise was fluctuating up and down so I unplugged it for the night so it wouldn't catch on fire or who knows what. In the morning I plugged it back in and it just made a hum. I tried to see if the impeller was jammed but when I turned it on the back of the pump with a screwdriver, it turned freely.
Now, this new pump is able to backwash the water and rinse the water as long as I need. However, when I put the multiport valve to filter, it will go for bout 30 seconds then cuts off. It tripped the circuit breaker on the breaker box twice randomly. (not each time I plugged it in on that setting.)
I'm having an electrician come to the house Wed to check out the wiring in the house. That particular receptacle has been problematic over the past few years. Also I read on here that a convenience outlet has to be around 5-10 feet from the pool, which would put it in the middle of my yard.
