I have a pole light standing less than 10 ft. from the pool. When the electrical inspector came, he said it needs to be GFI protected. A GFI breaker for my type of main panel costs about $200, I was thinking to connect a GFI outlet (which costs about $20) next to the panel, and then connect the pole light circuit to the "back" of the outlet which is also GFI protected. Is this OK?
