I'd like to add an exterior outlet for some landscape lighting.
Is it against code to "T" off of an existing electrical outlet that is already on a GCFI breaker and put a surface mount exterior box on the outside of the home?
All I'd have to do is drill a hole through the siding and for the wire to pass then seal it up behind the box with silicone. The outside box will have a rain shield and the flap type doors.
The circuit that the outside lights would be on is lightly used. (Clock radio and some lamps)
