I know this isn't welding, but I also know there are electricians on this site....I bought a 5000w portable generator to replace a unit that isn't running well.The last unit had a three prong 230V outlet that I simply made a wire to go to the three connectors on my 50A welder outlet in the garage (NEMA C6-50) and I back-feed my panel (after disconnecting from the street and only activating critical need circuit breakers)But this new generator has a 4-Prong 230V outlet (NEMA L14-30 plug needed)I bought a 6' piece of 6-3 with a ground to go between the L14-30 and the C6-50.The question is, what do I do with the ground wire? The welder outlet has two "hot" wires and a "neutral"....There is no ground.....Do I simply disregard it or tie it into the neutral?Thanks in advance.Roy BDartmouth, Mahttp://www.rvbprecision.comMM 185 MIGDiversion 165Purox W200 O/AGrizzly 9957 MillGrizzly 4030 Metal Band SawGrizzly 1050 Knife Belt SanderJet 1236 Metal LatheCM 14" Metal Band SawTP Blast Cabinet

Reply:Disclaimer - I'm not an electricianThe neutral is needed if you want to tap off 110 as if you were running the wire to a sub panel.http://www.nojolt.com/Understanding_...circuits.shtml
Reply:Buy a generator 'back-feed' panel or transfer panel and wire that to your main panel in the garage.  That type of panel has a recessed male plug for the regular generator extension cord (one plug and one receptacle) to plug into without having to deal with a male-male generator 'suicide' cord.Like this http://www.northerntool.com/webapp/w...1024_200221024or this http://www.northerntool.com/webapp/w...1033_200321033  The best laid schemes ...
