50 amp RV pedestal wiring

[kinglake]

I am installing a power pedestal at home to power my RV as needed. The pedestal is roughly 60' from the main panel. #6 cu is expensive so I thought about using MHF to go from panel to a junction box immediately adjacent to the 50 amp receptacle where I would use splicer-reducers from the link below to transition to #6 cu. Is this okay?

Yep, that's okay.

and then wrap it with some linerless rubber tape

What is the incremental difference in going with copper versus MHF?

Copper in conduit indeed will be more expensive but at the distance you are talking I am not sure I would be willing to deal with the required transitions.

Of course it is easy to spend someone else's money!

HDonline pricing

6/3 UF-B is about $4/foot
2-2-4-6 MHF is $1.80/foot

For an RV post, I guess you only need 2 conductors, plus ground.

Found 75' of 6/2 UF-B on eBay for $141 w/shipping. Comparable in price to the MHF which would supply 240V if you ever need it.

It needs ground and neutral so would need 6/3. I can get 2-2-2-4 for $1.20 whereas 6/3 is $4.21. The additional expense to transition is 4 of the splicer-reducers ($20 total) and a junction box ($10). I should come out quite a bit ahead going with the MHF.

I will put it in conduit either way so could go with individual wires ($240 for 500ft), however that isn't much cheaper than the 6/3.

Thanks to everyone for the help.

I will put it in conduit either way ...

You do know that conduit is not required for either, correct ?

The MHF must be in conduit above the ground and in a building. Use Schedule 80 conduit for any above ground area that might get damaged (the sweep where it comes out of the ground).

No the 50 amp RV is 120/240 with a neutral, so two hots, a neutral and a ground. Its basically a 4 prong stove connector, NEMA 14-50.

I have to say, you're worried about that price difference......for only 60' away???
When all is said and done, what are we talking? $100? $200?
I'd easily spend the money to not have to deal with #2 in this installation.

Can I ask how much the RV was that you are plugging into the 50A RV receptacle?

 

[kinglake]

$100 is $100. No reason to spend it if I don't have to. I will lay out the MHF and then slide the conduit on it from the end. Then push in the trench. Did the same thing to my shop and it was extremely easy. Actually easier than I anticipated. To your point though,the reason I am transitioning to the 6 at the receptacle though is because it would be impossible to get the #2 to fit in the pedestal. Or at least much more trouble than I want to deal with.

My mistake. I was thinking of the 30A version !

I always wonder why the RV industry chose not to follow the NEMA standard
