Finished my electrical system project today, in time for 5 nights of boondocking next weekend at the NA$CAR race in Dover!
First, I ran 12-3 Romex from the Xantrex to an area inside the TT adjacent to where the TT's 120v, 30A twist-lock male wall plug is located (for feeding the TT). I then put a 120v "standard" plug on one end of the Romex, so that it could be plugged into the Xantrex GFIC outlet.
Next step was to install a 120v duplex outlet with a flush-mount weatherproof box, right next to the 30A twistlock box. This outlet is fed by the other end of the Romex.
Final step was to connect a 30A, 125V female plug to 2' of 12-3 power cord, and a 120v "standard" male plug to the opposite end, making a 2' long adapter / lead-cord. I can now plug the 120v supply from the Xantrex into the TT feed with the 2' lead-cord.
By minimizing my microwave use (my heaviest 120V draw), switching the fridge to "propane", instead of "auto", and turning off the 120v to 12v converter breaker (so that I'm not trying to recharge the batteries with the 120v charger, which is drawing it's power from the batteries, through the Xantrex), I can now power-up all of my inside and outside 120v outlets.
All parts came from the local Home Depot. Cost, you ask???:
Two "standard" male plugs - $12
One 30A, 120v female plug - $30
One 120v duplex outlet in flush-mount weather proof box - $24
2' of 12-3 power cord - $4
24' of 12-3 Romex - free (on a spool in my basement, left over from a previous home project)
Total Cost: $70
Looking forward to seeing how well it works this upcoming weekend!
