Water heater and pump on 15amp? Also fan?

I'm looking to de-Winterizing tomorrow in my driveway and sanitize my fresh water tank and lines. I also want to see how things are working.

The camper is currently hooked up via a 30amp to 15amp dogbone elec adapter since it's just plugged into my house.

Will the elec water heater and water pump work on 15amp? (One at a time)

Also, I tried the turn the fan (not ac) on today and nothing happened.... Is that because I'm on 15amp or could there be a bigger problem?

Use the propane side of your water heater and your 12v water pump and you'll be fine. I'm not sure if the WH will work on 15 amps.

WH and nothing else big (microwave or A/C) will be OK on 15A.


But, northmec is right, propane would be a safer choice.


No fan on the A/C is not a function of your power limits. You have a problem that needs looking into. Breaker, wires, thermostat, etc.

The water pump is a 12V item, so you do not need to be connected to shore power. The 12V power system continually charges while plugged into shore power, so there is a little load on the system from the converter.

I have never tried running my WH while connected to the house's 15 amp breaker. worse case scenario, you will trip the house breaker (that is what it is designed for). The other item to keep an eye on is the 15 amp to 30 amp adaptors, some of the cheap ones will get hot, and if it gets to hot it will melt. I have not heard of this issue with the DogBone style adaptors. But still worth keeping an eye on it. All you have to do is touch the dogbone once in a while. If it is getting warm, turn off the WH or other heavy draw load.

I was afraid of this.

I run my electric water heater off 15A all the time at home. I have a meter that monitors voltage drop and as long as it stays in the green area it's good. The only thing I cannot run is AC
