    I have tied from my pool box to a shed 80 feet away. Ran 10/2 with ground to the shed and using a 15 amp c/b in the pool box. I’m powering five connection boxes and two 8 foot lights, is this a safe connection without a c/b box in the shed.

  2. Dave Rongey says:

    Well Daniel,
    Is it all on GFCI, is the wiring protected or is or exposed, was the feeder cable buried deep enough and was it type UF, and most of all did you do this with a permit and was it inspected?
    You see, I have been provided with very limited information, and it is not my place to make this decision.
    The bottom line about if your project is safe or correct rests with your local building department and inspector who can see from their position what I cannot from my position.
    I hope you understand.
