I have a hot tub (spa) hooked up to my house which is ran to a electrical box outside on my deck.the question I have is how do I run wire from the box which my spa is hooked up to, to the place I want to place an electrical outlet form my above ground pool pump I do have space for another breaker in the electrical box that my spa is wired up to.what type of wire do I use and gfi breaker thanks

For 120 volt gfi protected recpticle. If in conduit, Pull #12 black and white THHN from panel to spa box. Run 1/2" PVC with black, white and green to new location. Use GFI
Receptacle or Breaker,and Bubble Cover to keep weathertite with plug in.
Maybe wire for light?
To get wires in, maybe pull out green and pull in green, black and white attached.
