Bassman1,

I don't have any equipment/tools here to try testing anything myself and power electronics was not my specialty so my knowledge about the subject is minimal.

However, this is what I've been told.

The ELM-3600SS large outlet is both 110 and 220 volt. The full 30 amps is available to the 220 volt. What is not clearly understood by me is that I was told you may be able to get 20 amps off of one of the 110 volt legs out of that outlet and 30 amps off the other leg.

It is not clear to me how this is supposed to work. We need someone who knows what they are doing to open it up and check it out.

I wish I had some tools and test equipment so I could go check out the unit myself.

I have a lot of different duties here that keep me real busy but I need to be learning more about these generators so I can answer questions better and help support them better. The ELM-3600SS is by a different manufacturer than the ELM-3000, so I think I can get the wiring diagram.

I can be busy and not check here for a question, so if you have a question you for sure want answered, please send me a direct message, so I don't miss it.


Sincerely,
John Pearcy

I believe I can help you understand what's going on with the 3600SS generator. It cannot produce 30 amps at 240 volts(that's 240 x 30= 7200 watts). It can produce 240 volts at 15 amps( 240 x 15= 3600 watts). The two generator coils are 180 degrees out of phase(they add together 120+120=240 volts) as they are connected from the factory. Each 120 volt leg can separately supply 1800 watts(120 x 15) but as wired they cannot be tied together without shorting the generator. So you can attach two 120 volt appliances each that use 15 amps across the 30 amp plug or plug in 2 different appliances to the 2 120 volt household plugs(again each drawing 15 amps) but you cannot tie them together to provide one 120 volt at 30 amps as we as campers would like.

To provide 120 volts at 30 amps one of the generator coil leads will have to be reversed to place both coils in phase. In this way only 120 volts will be available but now instead of voltage adding together current adds together(15 +15=30 at 120volts=3600 watts). With a wiring diagam this should be pretty easy.

Did this help or make things worse?
