only able to use half the watts from my generator


I have a 5000 watt generator with a 20 amp 120v nema 5-20r outlet, and a 20 amp 240v nema 6-20r outlet. I can only get a maximum of 2400 watts of 120v power at 20 amps. Is their a way that I can wire a plug to get 120v from the 20 amp 240v side of the generator?

The generator internally produces two separate 120V 20A circuits that are out of phase, so they can also be used as one 240V 20A circuit. You can only run a maximum of 20A at 120V on each half of the generator. They are usually wired so there is one receptacle on each half of the generator. If there is only one 120V duplex receptacle, then it's likely that the top and bottom of the receptacle are on different circuits so you can run 20A on each. In the worst case, you may have to make a receptacle box that plugs into the generator's 4-wire 240V receptacle.

Yes, you can get 2 x 20 120v circuits !
But to do it safely would require a recepticule box to be made up.
The two hots would come from the nema 6-20.
and the neutral from the 5-20, 120v socket.
An electricain could make one quickly and safely.
