I want to utilize an old hot tub connection located in my backyard to install a NEMA 14-50 plug. The connection labeled on the panel is connected to a 60A breaker. I'll include an image of the existing wiring. Clearly there is a heavy gauge wiring which I think I can connect the 14-50 receptacle. However there is 2 separate set of wires of smaller gauge connected to each other which I have no clue about. My thoughts are that I connect the larger gauge wire to a 60 amp RV subpanel which would include a 50A breaker to the 14-50 receptacle.
