Generator to transfer panel wiring
I have a generator with a 250v nema 6-20 female outlet and a reliance generator transfer switch that has outlet box with a nema L14-30 male connector. Can I wire 2 different plug ends to a 10-4 wire to get the power to my transfer panel? If so, how do I wire the 2 different plug ends? Thanks. LAB

If you are attempting to run 120V loads, you need a generator outlet that supplies a neutral. That will mean, get a different generator.

Generator to transfer panel
Let me redefine the situation/question. I have a 5000w generator with 2 ea 120v (nema 5-15) outlets and 2 ea 250v (nema 6-20) outlets. Is there a way to connect the generator to a 6 circuit generator transfer switch with a L14-30 male connection. The circuits I want to power through the transfer switch are all 120v. Thanks.

I would think you should not do this.

Your generator has 120v (3-prong, hot-neutral-ground) and 240v (hot-hot-ground) outputs. You need a 4-prong 120v/240v output (hot-hot-neutral-ground). I suppose you could jerryrig something but it would be pretty crazy to take two 120's and attempt to combine them into one L14-30 plug. That cable contraption would have two ends with 120v plugs on them and so could be used incredibly dangrously if someone didn't know what the specific purpose of that cable was for and plugged it into household outlets.

Is it an older generator to not have the 120/240 output?

Reliance does make a 120V transfer kit. Of course it can't power 6 circuits. I would either upgrade the generator to the right power output or downgrade your transfer kit to the lower requirement. You could get two 120V transfer kits and take off the two 120V outputs of your generator.

The generator is a 2006 Coleman Powermate 5000.

The Powermate 5000 (current one) definitely has an acceptable plug. See the link below. I'm considering the PM 3000 (slightly smaller model) and the 6-switch Reliance kit for myself.

I have no idea if it was different in 2006.
