It goes into your breaker box and each hot goes to it's own bus bar. You get two hots and a neutral (and a ground) from the power company. If you want to use 240, tap into both sides (where the neutral is not really necessary). If you want to use 120, just tap into either side. each with 120v but in exact opposite phase. I've beat this dead horse quite a bit, but another simplification is to think of the center tapped (common) neutral as basically dividing the generator windings into two seperate generators. It would be analgous to saying if you only use one of the 120V 20a outlets on this generator you'll cause the windings to run imbalanced.etc. So theoretically, what the maker of the adapter cord says above is kinda bogus. Basically, using only one leg of the 240 leaves the other leg unused, which to the generator is no different from all the other 120V unused plugs. Yeah, i'm pretty sure i've got this figured out. so wouldn't it be doing the exact same thing, only running one hot down one side of the cord, and the other down the other. Also, they sell cords specifically designed to turn this 4 prong twist lock into 2 or more 120V extension cord plugs. GenTran is not responsible for any damage caused by the use of this cord."īut I don't know A.) what "long periods of time" means, and B.) is this just CYA stuff? So I called Troy Bilt and they said it's designed to run on either one or both legs. Connecting this adapter to your generator for long periods of time may cause the windings of the generator to run imbalanced which could potentially shorten the life of the generator. Since the RV TT-30 is a 125-volt only device, only ONE hot leg of the plug is wired, and the other would be inactive. "PLEASE NOTE: A watt generator normally runs 30 amps to each hot blade on the receptacle. ![]() ![]() The outlet is protected by a two pole rocker switch curcuit breaker."Īnd I found a discussion on an RV forum where someone pointed out this disclaimer on a converter plug set: This receptacle powers 120/240 Volt AC, 60 Hz, single phase loads requiring upto 6,000 watts of power at 25 Amps for 240 Volts or two independent 120 Volt loads at 25 Amps each. You can use the same 4-wire cord if you plan to run a 120 Volt load. Connect a 4-wire cord set rated for 250 Volt AC loads at 30 Amps (or greater). "Use NEMA L14-30 plug with this receptacle. I guess I'm making more of it than I need to. It's amazing how unclear this actually is.
