My old house has an RV outlet (NEMA TT-30R) mounted on the outside of an exterior wall. Since I have no use for this, I'd like to remove this recepticle and use the circuit for other purposes.
The raised printing on the recepticle says "Travel Trailer Use Only, 30A 125V." In the panel, there is a single 30 amp breaker that is clearly labelled "RV Outlet," and when I switch this breaker off, the recepticle is de-energized.
So far so good, but here's the problem.
The cable running from the panel to the recepticle has three wires (black, white, red) and a ground and is labelled E25682F (which is 10 gage, 3-wire w/ ground, direct burial cable). I had expected to see two wires and a ground.
The black, ground, and white wires are connected to the back of the recepticle, and the ground is also connected to the ground screw inside the outdoor junction box. The red wire is not connected to anything, and appears to be just sitting in the box.
Does this make any sense? It is possible that the previous owner just used whatever 10 gage cable he had lying around and that the red wire is not connected at the panel?
