If your only service panel is 100amps and is going to supply your 50amp RV receptacle and the rest of the house combined then you may need to upgrade it to 200amps. If your 100amp garage service panel is a sub-panel of a larger capacity panel you are good to go.

Not required. Upgrading the service is not a bad idea, it just can get very pricey very fast !

You can feed a sub-panel with half the current of the main panel. So if he's coming off a 100 amp main 50 amp sub is okay.

Thieves?

NYANNT...ZOOT...smoulder.

I don't know where that image came from...

I recommend that you install a disconnecting means at the new outlet - either a combo receptacle/breaker housing or a separate breaker or switch (suitably rated) in a weatherproof box/enclosure adjacent to the new recept.

If you are doing this 100% to code, you probably need to do a load calculation which would include the existing home's load plus the new RV outlet. It could be possible that by calc. you can't do a 50 amp outlet. But do you really need the full 50 amps at home? You *could* wire it all up for 50 amps (incl. wire) and install a 2p-30 amp breaker in the house panel - which you could always upgrade to 2p-50 amps later on.

A red wire would be nice and just personal preference and won't help except for maybe doing a diagnostic check some day. It's not like you have a switch leg or 3-phase. But you can simply take some red electricians tape and wrap it near the ends of the black wire.

50 amp is not required to have a GFCI but if you want one you can get GFCI circuit breakers for the sub panel in the garage

Your plan is good... Make sure the wire is heavy enough. I would go with at least 6ga

But you wont want to when you see the price of a 50A GFCI! :E

TRUTH.. I only point out that you can get 'em. THere is a reason (Clean underwear) I've never priced 'em.. Like to keep it clean and I'm fairly sure that might be a problem when I check the price tag :)

If you want to be anal use 1 red, 1 black, 1 white, and 1 green. 6 GA would be fine for 25 feet from panel to outlet. 1 inch might be a little tight. I used 1 1/4 inch for mine. I did not use a box with a breaker, but I am thinking about swapping it out so that I can turn off the power from outside. Just a convenience thing, not a code issue.

What ^^^^^^^^^^^^^^ this guy said.

I used 3/4" pvc when I pulled my 30 foot run with 3 of the 6g wires and a 10g ground. I am glad no one recorded what was said. I definitely would not use that size again, but think 1" may be OK. Do get a box with breakers in it so you can turn off the breaker to plug and unplug the RV. GFCI is not recommended on the 50 amp plug, but if you get a box with a 20 amp plug included, that can be GFCI. Even though I own a 30 amp RV. While I was doing the work I decided to plan for future RVs. I used a 50 amp/30 amp/20 amp box with breakers. I am running it off of a 50 amp breaker in the house, so I can not use all 3 outlets to max amperage, but 100 amps (50 amps on each leg) is plenty for me.
