camper to house?

I would like to hook my new camper to my home electrical system so I can use it as a "Guesthouse" when necessary. It requires a 30 amp dedicated circuit. What I would like to do is run from a 30 amp breaker in my main panel to a new subpanel in my garage. Should there also be a breaker in the subpanel? Also the outdoor receptacle has to be waterproof of course. I am not going to do the work myself because i dont know enough yet to try this big of a project, but am i on the right track? Also what size wire should
I be using, 10awg? Any input would be appreciated, like I said I am trying to learn as much as i can from the pros on here!

You don't need a sub-panel in the garage, run from a double pole 30 amp breaker in the main to the outside receptacle. 10-3 plus ground unless the run is much greater than 100 feet.

even better for me. That could save me quite a bit of money!!!!
One more question, how do I know or how can i calculate how much my main panel can handle? I have a 150 amp main panel.

If you take a litte time filling out this calculator you should be pretty close as far as your calculated load goes.

Just 10-2 w/ ground is necessary because it is only 120V and a single-pole, 30 amp breaker to match your panel. The NEMA number for the receptacle is TT-30R. Check your local home improvement store for an outdoor box. I used to work for an RV dealer and many customers brought in their RV after it was hooked up to 240V and fried everything.

That may be a good catch College Student, the only camper I have had experience with was my father's and and I thought his had a 220 panel.

At first look its an easy mistake. Your father may have a 50amp, 120/240V RV, the only difference from residential, is the RV doesn't have any 240V fixtures/appliances; just 2 seperate hots.

You are losing me with the last sentence.

A 50amp RV (cord) has 2 hots, 1 neutral, and 1 ground. There normally are no 2-pole breakers in an RV panel because everything runs on 120V.

I hope that clarifies the verbosity.

It may in some situations be true that 50amp services are single pole and even double pole and 120v but there are many that run 240v appliances at 50amps off of two legs of single phase…………

By the way college student………… You may want to spell “separate” correctly………
