Mapping my 120ACV in RV

I am trying to find out what the breaker labeled Water Tank Heater. I am not sure if the labeling of breakers is factory or if a previous owner labeled them, but the Water Tank breaker is in a different hand. What I do know is that the water heater does not have a 120 outlet. I have gutted my kitchen and no outlet exists for the domestic water heater. Note: I didn't gut the kitchen to find the outlet.

Thoughts please

I have a 3611 and the water heater is powered by a 12v source. Would be in the panel next to the 120v breakers and the fuses would look like automotive fuses if you are looking to isolate it.

Dometic G6A8E, if yours was gas/electric combo the model would be GC6. Check the model by dropping the exterior panel and looking at the nameplate if you are unsure.

The breaker might be the only control if it's for a set of 120v tank heating pads.

The pads draw around .5 - .8 120v amps and usually self control with an internal thermostat that only kicks in when temps at the tank interface drop to ~40f then shut off at a preset temp in the high 50s or low 60s. They are also generally installed in a series for black, grey, and fresh all running off the same circuit.

A somewhat lazy previous owner might have installed them after purchase (hence the different handwriting) and just used the breaker as the control when needed since they self switch thermostatically.

If you have amp-meter, in theory you could test by flipping the switch when it's warm out (no draw) and again when it's near freezing (some draw around 150 to 250 watts).

YMMV

Mine doesn’t have that breaker, nothing after the one labeled GP, same year and model, 2007 3611, my hot water is propane only

Gents thanks for your thoughts. My old water heater was propane with a 12VDC power supply

Found it!! A previous owner added a 15amp circuit to the sewer bay. The thought must have been to add a small heater to that bay during freezing weather. Hence the reason for different handwriting on the label.
