50 amp welding cord to 50 amp rv cord

[JSPERRELLA]

Is there a way to use a 50 amp welding extension cord as a morohome's 50 amp extension cord?

Are you asking if a 50Amp/250Volt 8 Gauge/ 3 Wire welder extension cord can be used for 50 AMP RV cable service? If the answer to that question is yes, then the answer is Not legally. A RV cord is 4 wire (L1, L2, Neutral, Gnd) not 3 wire (L1, L2, with shared Neutral/Gnd).

Neutral and Ground are only suposed to be connected at the main dwelling Power Panel (powerline transformer input point).

I was afraid so.


Know anyone wanting to purchase a 30 foot 50Amp/250Volt 8 Gauge/ 3 Wire welder extension cord cheap??

Plain and siple NO! I would assume the conductors for the welder would be number 6 as well as it would be a 50A service but the difference is that the welder would be a 3 conductor and the rv cord would be a 4 conductor. Pin configuration for the male and female cord ends would be a Nema 14-50. Hope this helps.
