Do you have an energy management system that shows the amount of amps being drawn when operating on 30 amp. or generator. Usually does not show when on 50 amp.
When I flip my elect. water heater switch I see a rise of 12-13 amps. showing it operating, plus I get hot water pretty quick. I cant see a great deal of difference between elect. or propane

I have 2 switches in the control cabinet at the front of he MH. One for propane & the other for electric. There is no way to tell the electric is on ( no red light or else). There is a red light that would indicate a misfire on the propane but otherwise it's not lit.

Yes I do have a EMS. That's part of why I question the electric not being on. I was connected to 50 amp and it showed the water heater as "on" but there was no amp usage. I even tried it running the Generator and it showed the same 0 amps.

I'm going to have to pay more attention on my next trip. I will keep the propane off and see ow it goes.

Thanks for the replies!

An EMS system will NOT show amp display or usage on true 50 amp service. On APU, does it show ANY amps? If you have a single phase APU (less than a 10k APU) it will show the amp draw of the RV on Genset. 10k and above are 2 phase output APU's and because of THAT, the amp display will be blank. If you want to show the amps of the Water heater just for your knowledge, connect your shore cord to a 30 amp plug with the 50 to 30 adapter. Leave all 120 appliances off just for this test, then turn the Water heater on 120 and watch the amp display. W/H'ers usually pull anywhere from 10 to 11.5 amps. Doug
