Question:

I need to know on the other end of the L14-30 female connector, the 3 prong plug that will plugs into my generator how to connect the colored wires. I have a red, black, white and green. I know the red and black are hot for each side of the plug , but do I use the white neutral or green ground in the plug. If I use the white does the green ground get attached to the ground nut on the generator?…. Thanks

Your power cord just like with the Epicord RV Power Cord with Handle # 277-000154 will wire the black and red wires as your positive, white as your neutral, and green as your ground. The green wire should not be sticking out of the sleeve like you have pictured and the plug should have a ground nut on it. Since you have four wires that is a 50amp power cord. If you purchased the black plug separately and it doesn't have four connection points then you most likely purchased a 30amp plug instead of a 50amp one. If that is the case and the generator requires a 30 amp plug you would need wire the pigtail to a 50amp plug like # HU63FR and then use a 50amp to 30amp adapter like A10-3050AVP between the power cord and the generator.
