Thanks in advance guys...
Is it possible to take two 15 amp outlets from different breakers and connect them to make one 30 amp?

You could conceivably create a 240 volt 15 amp line.
The problem is the outlets would have to come from different busses and would be unsafe without a breaker tie.

Like learjet said "No, please don't even try".

possibly yes,,, if not on different phases as you may get 220 as you would if between both hots on a 50amp outlet. Very careful meter testing would be required. For the average Joe,, Don't do it. Your double male plugs would have one hot after the first one is plugged in so their is a danger of a fatal shock from the second exposed plug until it was connected in. A suicide plug it is called.

If you have to ask, DON'T DO IT.

Ditto on what melton posted.

Playing with electricity without proper knowledge will kill you. If you had to ask the question, you should not be messin' around with it. Otherwise you or other folks could become Darwin award winners (not a good idea).

MCrankyPants,

As others have said, it shouldn't be done. They mentioned the more obvious reasons as to why it should be implemented.

Theoretically, in a perfect world and assuming it was wired correctly, you could do it. Sort of. But it's STILL not safe. Here's way.

Even IF you DID wire it correctly (2 separate 15A circuits on the "same phase"), then the biggest problem would be the neutral currents. The neutrals to each 15A circuit would be connected together on the 30 Amp plug just like the hots. The problem is that due to differences in resistance in each neutral path, the return currents could be different. Example (perhaps a bit extreme): You wired it up and you're drawing 25 amps (12.5 amps from each hot). Everything looks OK. However, due to a difference in neutral paths, one neutral could carry 22 amps while the other only carries 3. Since the wires are sized for only 15 amps and that there is no breaker in the neutral wiring, this is a potentially dangerous condition. The neutral wire and connections on the overloaded side will heat up and eventually WILL cause problems.

So, aside from the practical reasons for not doing this, even if you COULD do it, you are playing a game of chance that the neutral wiring won't be overloaded.

So, as others have recommended, don't do this. There really is no way of doing it that is safe.

OK, all you nattering nabobs of negativism (remember that phrase? who said it??) What if , as I read & re-read the question, he means two 15 Amp breakers fed by the same bus - would that work? - if not, why not?
This forum get the darndest questions!!

Joe see Rick's answer right above your question.
