Hi… totally confused and don’t pretend to be an electrician.
My pool timer went out. It’s a T104. I changed it out and checked the volts on it. It’s a head scratcher. There’s a 40 amp double pole breaker in the panel. Each breaker tested out at 120volts for a total of 240v.
At the new timer next to the pump line 1 from the panel tests out at 120v but line 3 tests out at 240v. Totaling 360v on the t104 pool timer. Line 2 matches line 1 at 120v when operating. And line 4 tested and matched line 3 at 240v. I’ve never seen something like this. All I did was change wire for wire. How is it possible to get 120v and 240v when the breakers in the panel are 120v and 120v. And I’m not sure. Is it safe to run it this way or not. In addition will it burn out the pool pump. How did it grow in volts. I’m assuming it’s been this way for the 3 years I’ve owned the house. Last thing. The pool pump used to start hard and was more powerful in the old timer. On the new timer the pump is quieter and doesn’t pump as much water.
Any help would or advice would be greatly appreciated. Thank you.
