I have a 30 to 15 amp adapter that I use occasionally connected to a 20 amp outlet. Does anyone know where to get an actual 30 to 20 amp converter plug. All I have found is 30 to 15 amp adapters. Since I plug into a real 20 amp outlet & circuit, I would like a real 20 amp plug. Then I can set my EMS to 20amp and not be concerned when pulling 16-20 amps. Sometimes the 30 to 15 gets a little warm.

20/30 adapter at CW

If you prefer a dogbone style you can buy a 30 amp connector with pigtail at CW and a 20 amp plug at Home Depot. The truth is the 15 & 20 amp plugs are built the same with just the neutral twisted 90 degrees on the 20 amp. A premade 15/30 dogbone is fine as long as #10 wire is used, some have #14 and that will get hot.

Uses 2 15amp outlets instead of 1 to reduce heat and plug falling out



If you have a duplex 20 amp option you may want to try this. I have order my tonight but have a shop made version that stayed cool running the A/C and other normal AC load.

Just bought one at CW. Appears to be a good product.

I confess that I bought it because it just looks better than a dog bone hanging off my generator.

Caution. This may cause a problem with some Chinese generators. Some use a center tapped generator unit providing 230v and pipe each half wave of 115 volts to each outlet.

The "Professor" has a wonderful but huge thread that explains this so much better than I can.

So, some do -- some don't / some will and some won't, as the song goes.

It that case everything should go twice as fast. I do not plan to use with the China gen set but I will try and remember to check the voltage with it plugged into that gen set so thanks for the heads up.

Mainly I got it to have when I want A/C but no 30 AMP connection but a 120 duplex connection like at one camping spot. Geeks like this kind of junk.

You answer is quite cavalier. and it may become injurious to some set ups and owners.
we have a duty on these posts "to do no harm".

Before anyone tries this trick, please look thru Professor 95's complete explanations of how some generators do no re-process the second cycle and it is in apposition to the first plug when sent to the second plug. Will burn out your motors.

Harry I felt your last post made it very clear some China gen sets had seperate wiring to each half of the the 120 volt duplex outlet that by design could make a 15 amp duplex to 30 amp RV adapter give an output of 230 volt blowing up any 120 volt devise hooked to it.

I will try to find the article you mentioned because it would seem the adapter would "wire" the two sockets together and that could damage the generate. While I only plan to use the duplex 15 to 30 amp adapter plugged into household connections I still am interested in the case you point out. Thanks for the heads up.

You don't need a 20 amp adapter- the 30 to 15 will work just fine.

15 Amp is rated up to 20 amps

20 amp Plugs on products are there so that there is no chance to plug in to a 15 Circuit.
