How To Install The Dometic RV Water Heater When You Don't Have An AC Outlet

Question:

My old Atwood water heater gas / electric installed in a 2004 Bigfoot 30Mh29SL, my old unit was/is hard wired. I see the DometicDMC74FR has a 110 plug. How do you resolve this wiring issue?

If your current water heater is ran from the AC distribution panel then you could just disconnect the power, ground, and neutral from it and get a 15 amp GFCI outlet, 1-gang electrical box, and an outlet cover to wire in an outlet for the Dometic RV Water Heater # DMC74FR to plug into.

If your previous unit was only DC then you'll need to also pick up some 14-2 wire from your local hardware store and run the lines yourself. You will also need to use a 15 amp circuit breaker in your AC Distribution panel for this unit.
