Just got my Active20 and I need to figure out how to add a plug for the power supply. I have a 20A double pole breaker in a subpanel that is feeding my timer that my pump and SWG are connected to. I also have a 15A single pole breaker for by non-functional fiber optic light. I think it is a GFCI, becasue it has a test button on it. How could I connect a 120V outlet to plug in my Active20? Can I connect one the hots, the neutral, and the ground to an outdoor rated 120V outlet before the leads go to my timer?
