30 amp rv receptacle generator#

Adapters that provide a 30 amp/120v RV outlet from another type of plug, such as a 14-30 or 14-50 (or locking versions of the same) are using the ground, the neutral, and ONE OF THE HOTS. It is ONLY capable of providing 240v current (the two hots). The problem is this, the welder outlet has NO NEUTRAL, and thus cannot be used to provide 120V current. Note that only one hot is being used by the adapter, the other hot is dead-ended in the adapter.

If the generator is producing more than 30 amps, there is a safety issue of overloading the RV input cord, but hopefully the RV has an internal 30 amp fuse or breaker that will trip in that situation.A 50 amp RV outlet is a NEMA 14-50 and it has two hots, a neutral and a ground, and 120v can safely be drawn from it using an adapter. If the generator is not capable of 30 amps, it will merely trip the generator output breaker when overloaded. The 30 amp/120v RV/TT plug is safely supplied by a generator producing 120v current. The lack of a neutral on a 'welder plug' is what leads to your next issue Plugs with grounds will have a round or D shaped pin, plugs with three flat blades such as old dryer and range plugs, have two hots and a neutral and NO GROUND. The welder receptacle/plug (NEMA 6-50) has no NEUTRAL, just a ground. Is the risk there, but very unlikely to occur? Or is the risk very likely to occur? I believe the warnings are probably correct, but I don't completely understand the issued because the warnings. I would like to be schooled on what the deal is with this. NEVER, NEVER, EVER plug an RV into a welder outlet (using a homemade adapter) because the welder outlet has no grounding protection and this could/will cause serious problems for the equipment and devices plugged into. The trailer owner has used an adapter to plug the trailer into a 50amp RV outlet. The trailer has a 30amp RV plug plugged into an onboard generator. The trailer is used for cooking and preparing food. Lets say an enclosed utility trailer has a freezer, a couple of refrigerators, and a few outlets for food prep machinery. Am I correct so far? If so, what about the ground? Does a welder not have a ground wire?Īn 50 amp RV plug will have four prongs: a pair hots, a common, and a ground. I understand that a 240volt welder plug has only three prongs (I believe two hots and a common). I'm not an electrician or electrical engineer.
