when we bought our house it only had 1 outlet on the outside of the house on the front of the house pretty much right in the middle of the house.
we have a pretty large concrete back patio but it doesn't have a single outlet on the back of the house.
in the front I would like to add one close to the boat for charging the battries.
my plan is to come from the inside of the house and just piggy back off one of the outlets on the inside. Found where they have the "old work" type boxes and will get GFI outlets and water proof covers.
my question is on wire. is 12/2 fine for wire?
I'm not an electrician but I know many on here probably are or know more than me with this. I would think that 12/2 would be fine but want to ask first.
