Two L6-30P to one L14-30R


We've got a concessions trailer that's currently powered by a 240V generator, though everything inside can run on 208V just fine. We would like to run the trailer on power from a building rather than the generator because the generator is quite loud and annoying.

The problem we've got is that there are no L14-30 plugs in the building. However, we do have a power distro (hooks up to 3 phase) that has 3 L6-30 receptacles on it, as well as another that has L21-20 receptacles on it.

We could use the L21-20 and make an L14-30R to L21-20P cable however that would limit the total power draw of the trailer to 40A so we wouldn't be able to run everything.

Another idea I had was to make an L14-30R to two L6-30P cable and have one hot and the ground go to one L6-30 and the other hot and the neutral go to the other L6-30. However, I'm not sure if this would be correct as you'd have the neutral line going into what would otherwise be the ground. And at this point it seems a little sketchy but since I imagine the neutral going into a ground would be bad, and since the neutral would only be used by the 120V appliances in the trailer, could you just have the neutral go to the neutral leg of a L5-30P (on the same distro as the L6-30P)?

Just have an electrician install the proper receptacle in your "power distro". It shouldn't cost that much.

Don't come up with ideas, just hire someone to do it right!
