Added 20 amp circuit to TT
I got tired of tripping the main 30 amp breaker every time my wife turned on her 1800 watt hair dryer whenever the A/C and electric water heater were also running. I added an additional 20 amp breaker box under the bathroom sink. To feed this, I ran weather proof 12/3 cable from the breaker box through the floor to a weatherproof plastic box. I then use a 12 gauge extension cord to the standard 20 amp 110 v outlets on the RV park service box. From the breaker box under the sink, I wired a GFI outlet through the face of the sink cabinet and from the load side of that outlet I ran the 12/3 cable under the TT to the kitchen and installed an additional 20 amp outlet (with GFI protection through the bathroom outlet) for coffee pots, toasters, convection ovens, etc. So, whenever there are standard 20 amp/110 v outlets available in addition to the 30 amp outlet, I now have 50 amp service available. Works like a charm.
