Hope this is ok to post!

I have a 4000 watt generator for my stoker.

Question:

When a GFCI duplex is rated 20r. Does this mean you can have up to 20 amps per jack plugin (which would really mean 40 amps before tripping) , or a total of 20 amps between both jack plugins all together running at one time? Thanks!

I think most outlets rated TOTAL for both. So 20 amps for both sockets. over that, it should blow. I don';t think the wiring would handle 40 amps.

20R is actually the configuration (shape and orientation of blades) of the outlet if I'm not mistaken. If the outlets on the generator are duplex, I believe the 20 amp is for the pair. If they are not duplex, each socket would be rated at 20 amps.

If its a GFCI, and there is only one set of RESET/TEST buttons, then the 20amp rating is for the duplex pair. If EACH 20r has a set of RESET/TEST buttons, another words, there are TWO sets of RESET/TEST buttons, then each outlet is rated for 20amp.
Press the test button, and see if you loose power from BOTH outlets.

Coaledsweat is correct, the 20R is the configuration of the receptacle. Your regular GFI plug is rated 15 or 20 amps and that is for booth outlets as the plug will be on a sp 15 or 20 amp breaker.

Let's see. P = V x A. Power equals volts times amps. Basic. 4000 divided by 120 is somewhere around 33. two outlets. Hmmmmmmm. :? :?

That is correct but, it would be two separete duplex outlets supplied by two separete 20 amp circuits not just two outlets ... just to be clear. :) There are those that don't know the difference.

Yep, Two outlets, but only one circuit. Has to be two circuits :shock:
