I am in the process of installing a 15x26 Sharkline Matrix AGP. I wanted to make sure my plan for the electrical is OK.
I currently have an outdoor outlet on the side of my house. It is a weathertight, in-use, GFIC outlet. The issue is that it is 20 feet from where I want to put the filter/pump. My plan is to tap off that outlet, then run three 12G THHN conductors through PVC conduit in the ground, and then up and directly to the pump. Since that run is not protected, I would install a 20A GFIC breaker back at the main panel for that circuit. There isn't much else on that circuit, just a few outdoor lights, so the load shouldn't be excessive.
My thought is that the existing outlet now becomes my "convenience outlet", and since it is 20' away I don't need any special twist-lock type plug. Plus, its GFI-protected via the breaker. Any thoughts?
