50 amp or 30 amp hook up at home

Read the articles posted earlier. Good info there. RV 50 Amp setup is indeed 120 & 240 service. The is a ground, neutral & 2 120v hots. If you do not know what you are doing, get an electrician. Be very clear that it is an RV 50 amp service and that the electrician understands that.

It's an easy change and shouldn't cost more than a couple of hundred bucks for an electrician to do it.
You'll sure enjoy having full power available though!

My circuit breaker in my house is a 50amp breaker.
And another 50 amp one outside.
Thought it may be some what easy to do.Going to just have to ask a electrician.
And pay the cost.

Spa's with electric heat have 50A circuits.

The basics are in place at the spa pedestal for your RV with a couple of caveats:
1: check the size of the wire feeding the spa pedestal. A 50 amp double pole 240 VAC service should be 6 ga or larger. The breaker at your main box which feeds that circuit needs to be the appropriate size also.
2. If the wire size checks out then you are good to go with a 50 amp double pole at both ends. If the wire size is smaller then you can still use a double pole breaker but drop to a 40 amp or even 30 amp. Your current spa breaker is most likely a 30 amp double pole. You will still have double the wattage available with a 30 amp double pole than a 30 amp single pole. You can use the same 50 amp connectors.

I guess I should of clarified it better.
I have 220 going to my hot tub now.I would like to use the breaker box (if I can) to put a 50 amp plug in it.Or will it only 30 amp be acceptable.
Right now I am plugging my 5ver into 50 to 30 to extension cord to a outlet

OK, if you have room in that breaker box for a duplex 50 breaker (which is two 50 amp breakers pinned together) you can easily install a 50 amp RV outlet. You will have L1 hot from one breaker, L2 hot from the other breaker, a neutral to the panel neutral bus and a ground to the panel ground bus.

As suggested, your spa will have GFI breakers which are not always compatible with RV power, so it is far better to have them on separate breakers.

And, yes, of course if you measure from L1 to L2 it will read 240 VAC. From either L1 or L2 to either neutral or ground will read 120 VAC. PERIOD.

One point to consider is the spa should have had a 50A GFCI protecting it and sometimes they don't like starting large motors (makes them trip because a motor "looks" like a ground fault). And yes I realize the spa had a motor.
So if you turn on the AC and the GFCI trips it will need to be replaced by a normal breaker.

Agree hire an electrician. 30 amps would be a 110v and 50 amps would require a 220v circuit.

No no no, 50 amps is 2 120v circuits !;)

LOL

I think I just saw a piece of the sky falling. :W
