I have a old (1980) portable generator with a 30A, 240V twistlock receptacle (3-prong) with 2 hots and gnd. It also has 120V, 20A receptacle as well on the panel of the generator.
Do I have to run a seperate neutral from panel to the generator and terminate the neutral to the neutral at the generator? Or do I connect the gnd from the generator receptacle to the neutral at the panel?
Thanks in advance
