    50 Amp to Welder outlet

    Hello,
    I am at my brother-in-law's place and he has a Welder 3-prong outlet box, which doesn't match my 4-prong 50 Amp cable.
    But we exchanged that outlet box for a 4-prong that will plug in. However, (without it being plugged into the RV end), my Power Surge Protector lit up an Error indicating the 'Neutral wire' was missing.
    ...What should we do now?

    Thanks, Craig E.

    Yes, but it is wired differently than a welder plug or home dryer.

    It is 2 legs of 110, 4 wire.

    huntr70....I agree. Maybe a better way for it to be phrased would be like this....the 50A welder plug is 240V.....and it is ONLY 240V. The RV plug (NEMA 14-50) is also 240V, but it functions as two 120V circuits because of the way the breaker panel is made in the RV.

    Yeah, probably.

    Biggest lesson to learn here is to not adapt electricity unless you know what you are doing.

    That's correct.240 enters the trailer as two out of phase(180degrees) and whatever type of panel it goes to splits it into the two110 legs. Also, while it's called 50A service, it's actually 100A because both legs can carry 50A.

    There is NOT any 220 V use in a 50 amp RV Circuit. It would destroy every electrical appliance in the rig and more.

    I'm quite aware of that. It is 220V up to the converter where it is splits into the two 110V legs

    Mostly, you are correct with that statement, but.........and there's always a "but"..some of the higher end Diesel pushed do utilize 240VAC for Clothes Dryers in them. The next comment is, just because there is not anything in the RV that uses 240V (vs. 120VAC), that doesn't mean that there isn't 240VAC in the trailer. The two hot leads coming to the line side of the main breaker....240VAC from L1 to L2.
