Electrical on 2019 31BH

My girlfriend just bought a 2019 Wildcat 31BH. I needed to know if it's 120 or 240 VAC for shore power.

110.

Be careful here. Some “professional” electricians mess this up. Do a lot of damage. For them these plugs are unusual.

3 wires and a ground to the plug. 50 amp. Two 50 amp 110 circuits.

Many install a 30 amp 110 circuit to save money. Be careful.

I think that unit is 50 amp, so it will have a 14-50 plug.

Look at the plug and if it looks like the one below then it's 240 volt 50 amp. Otherwise it's 30 amp 120 volt. The 120 volt is VERY important in the 30 amp service.

I know. The label on the side of the RV can be confusing. RV's are unique. Although there is 240v "feeding" the RV, it's actually split into 2 110v "legs" or circuits. The 4 prongs (if it's a 50amp supply) on the pedestal/cord are 1 "side" = 110v, the opposite prong/slot =110v, top = ground, bottom = common.

So, half of your RV is fed by 1 110v "leg" and the other half is fed by the other 110v "leg". You'll notice your electrical distribution panel probably has 2 rows of circuit breakers. Each side is fed by 1 of the 2 110v "legs" & the other side by the other "leg".

Hopefully, I didn't oversimplify but, not knowing your electrical knowledge combined with my limited understanding, that's how it was once explained to me.

Hope this helps.


Edit: It took me so long to type this, I now have to say...see above.

With either 30 amp service or 50 amp service both ground and neutral MUST be used otherwise you will fry some appliances or may create a hot skin condition. These documents and pictures will help.

The original question was about voltage, not amps. In my experience, it would be extremely rare to find any RV that uses 240 volts, regardless of 30 or 50 amp service. I think it's confusing, especially for newbies, trying to explain the 240-volt situation even though, technically you could get 240 volts from a 50-amp service by crossing the two hot legs. Seems to me it would be easier just to tell them they have two legs of 120 volts each and leave it at that.

this may seem like a stupid question but why do you want to know? are you going to plug into an existing outlet or are you going to build a new outlet? look at the end of the shore power cable and count the number of pins. are there 4 or are there 3? are you going to plug the shore power cord directly into the receptacle or are you going to use an adapter? believe it or not you can get both 120 volts and 240 volts on both the 4 pin and 3 pin receptacles depending upon how they are wired (or miswired). knowing what you have and what you intend to do with it will help get you pertinent responses. whatever you do, do not plug into any plug until you have confirmed that it is wired properly for an rv! plugging into a non proper receptacle will cause damage!

If you are having an outlet added to your house to power it at home, be sure to provide the electrician with the diagram above. There are many horror stories of electricians unknowingly wiring up outlets wrong and damaging many of the appliances in the Rv.

The reason for the original question is because her brother-in-law, who is a certified master electrician, will likely be adding the outlet on one of his power poles on his property for her to plug her new rv into. I know it requires 50 amps, but didn't know if it needed to be 120 VAC or 240 VAC. But y'all have been a great help! In explaining about the 120 on each blade, and the diagram, I can show him and he will know how to wire up the plug. Thanks guys!
