Need outlet wiring help. Can I use 220 volt wiring?

That's what I suggested way back.
It's amazing how badly a thread can get blown out of proportion.

Since the issue is clouded up, why not just wire in a new 50A 220 V Rv pedestal and use a dog bone for the plug in of the camper? :h

Yes it Can be Done.. You can use one of the hots as your feed and disconnect the other hot and RE-WIRE IN PANEL and use it as your Neutral and leave the ground as is!! But it doesn't sound like you know a lot so it may be best to Hire a Electrician! Good Luck

You might want to determine what size of wire exists and if it's able to carry the current to that location for your new use without excessive voltage drop.

I know most 240V service has wire of sufficient size but I've stood face to face with an electrician that told me 12 ga will handle the 65 A necessary for a hot tub. Best to check first.

Since you've had to ask here...get a qualified electrician to do the work. So far, you've not said anything about the service supply for the hot tub. How old is that circuit and are you positive it was EVER wired correctly? I've seen lots of jury rigged electrical work when I did contracting work...Surprises are the LAST thing you want when working with electricity.....Dennis

That is not correct. There are several hot tubs that are strictly 240V including mine, that don't have a neutral. The pumps, lights, blowers, etc. are all 240V. No need for a neutral to create 120v(just like your home air conditioner).
To the original poster, I would have an electrician see just what your old hot tub had for service. Even if it was a 3 wire 240v he could use the existing wires to create a 120v-30amp rv setup with a hot neutral and ground.

RoyB's post pretty much shows it all for you. Here's some extra reading material.

And take Mexicowanderer's advice and triple check before you plug you TT into it.

1st objective

Determine the circuit breaker amps used for the hot tub.

Second

Your camper must have it's own 30-amp SINGLE not ganged breaker. Make it weatherproof alongside the receptacle used for the power pedestal.

3rd

Sounds like you're rural bit it doesn't hurt to verify that your nee installation does not violate some arcane building code.

Take your time and triple verify that wiring is oriented correctly before connecting your rig.

I failed to mention that I have a 30A camper. I was at first going to wire in a 30 amp outlet to the outside panel box but then I remembered that I had a 220 wire that used to go to the hot tub (that I no longer have) just sitting there not being used so I was trying to determine if it could be used to power the camper.

This is a typical PEDESTAL wiring for both 50A and 30A wiring. Might give some ideas what to look for...



Once it is wired up then you want to test both the 50A and 30A and hopefully can come with these two measurement tests with no deviation...

50AMP


30AMP


The 50A side is nothing more then two legs of 120VAC 50A service feeding two ZONES of 120VAC CIRCUIT BREAKERS.



If you have a electrical contractor doing this for you then make sure they know they are providing service for a RV trailer.
