RV CONNECTION

[bgant4]

Does anyone have a wiring diagram for a 50 amp hookup? I understand rvs only have 110 volts going to them.

THANKS GUYS FOR ALL YOUR INPUT. IT HELPED

A side note:

The problem comes in the 30 amp outlets. The RV 30 amp outlet is a 120v outlet, but looks a LOT like a 240v 3 pin welder outlet. Many, many electricians have mistakenly wired it as a 240v outlet and burned up the electronics in many, many RVs.

The RV 50A is actually a typical 4 pin range outlet. Clothes dryers use 30A 120/240V outlets that have a different blade shape configuration. Both are wired similarly in terms of where the neutral, ground, and two hot wires are in relation to each other.

It is indeed the 30A outlets that are usually the source of confusion. They look superficially similar to the older three-wire dryer outlets (which I guess some may use for welders as well, though I'd think a NEMA 6-30 with coplanar power blades would in theory be more correct.)

I stand corrected.

Friendly Tip

Quadruple check the power connection legends. Make sure you are checking L1 to Neutral and L2 to Neutral. This means it is imperative you are 100% sure that you selected the neutral pin correctly. If you are unsure about your neutral selection stop! Get help. This is no time or place to rush things or daydream.

You've got some good replies but why do you ask? Are you just curious or are you about to do something that could get you into trouble?? 🙂

One thing I can add is that 50 amp RVs can be great for extra power for multiple AC units and being able to run other loads simultaneously. But often you will find campgrounds that have very few 50 amp pedestals, or sometimes even none. The reason is because the NEC code minimum requirements are waay behind the times with all the 50 amp RVs that are out there nowadays. The latest NEC edition only requires 20 percent of pedestals to be 50 amps and older editions a lot less. If you stay in high end RV parks and some gov't CGs, you can find more 50 amp pedestals because they were built above the min. code requirements.

I have seen many, many RVs at CGs with 50 to 30 amp adapters. Sometimes, even an extension cord hanging out the window of very expensive MHs into the 20 amp receptacle in a pedestal.

This is a pretty good look at it...


And if you measure this with your multimeter then you are pretty good to go for RV hookups..

The 20A/15A SERVICEis wired the same as the 30A except with proper rated circuit breakers

A 50A plug is 120/240V and you have that all the way to the dual CB in the panel. Most RVs use just the 120V capability but 240V is available.
