30 amp circuit install

I was originally running off a 15A just to keep the batteries topped off when I realized I could easily add a 30A service on my outside garage wall.

I built a new garage 5 years ago and I had them wire a 30A 220V circuit in case I ever needed it.

The box just had a blank cover on it.

So I took the cover off and drilled a hole through the center of the box and through the wall.

I then just tapped into one of the hot wires for 110V and ran it and the neutral and ground through the wall.

I then installed a 30A service box with its own breaker on the outer wall.

Worked out great and it was right wear I park it.

230 Volt 30 amps. I think what you are seeing is the 110 running under the box to the demand water heater on/off switch. Now pics are sideways. Sooner or later I'll figure out how to prevent that or fix it.

Plug for RV

When I did my 50 amp plug I wish I had gone ahead with multiple outlets 50/30/110, along with breakers.

A couple days late...

When we added a 30x40 ft shop building a year and a half ago we had the electrician install a 30 AMP outlet outside for our bumper-pull RV but we never used it.
We bought a Class C motorhome in April so now needed to get busy and get a pad built. Got that done two weeks ago and moved the bumper-pull to the pad and plugged into the 30 AMP box.
(some of you already know where this is going)
For some reason the 12 volt stuff was working but not the microwave, A/C, etc, I finally decided the convert must be shot (it's 14 years old) so ordered a new one which arrived on Friday. I carefully installed it that afternoon, even called a guy named Randy to be sure it was wired correctly, plugged it in and turned on the breakers one at a time until -- POOF! blew that large capacitor on the new converter.
I called the supplier (won't mention the company by name but to me they are the Best Converter company around.)
I talked to a guy named Randy again and after about three minutes he said something like "Well, there is something that happens more often than you'd think. Check to be sure your electrician wired it for 110 and NOT 220."
I checked it with my multi-meter -- that Randy guy is a genius!
My electrician will be back out this week to re-wire the outlet for 110.
Can't blame the electrician because it didn't dawn on me either that it should be 110, I just assumed a licensed electrician would know what to do when I told him to install "a 30 AMP outlet for an RV".

Anyway, $live$ and $$learn$$. We're totally new to self-contained motor homes, still a little wet behind the ears to RVing in general, and learning more every day.

This is a great forum and I have a LOT more to read.

Boy you would think the electrician should have known that!

I guess that it helps to know how to ask for exactly what you want...

But even if he'd have asked I would have said 220.

Our relatives on the farm had a circuit installed just for us on their pole barn. Nice of them. I told them 30 amp RV 120 v. When we got there I checkeck the panel to make sure and it was. I also plugged in my surge protector and powered the circuit to make sure it was OK, only then did I plug shore power in.

50 amp

I just had an electrician run 50 AMP to my garage door wall. I am not an electrician and did not want to take the chance. $375 but It can run everything when it is sitting in the driveway.

Just got this RV panel installed outside my garage.
https://www.amazon.com/Siemens-TL137...32207842&psc=1

Siemens TL137US Talon Temporary Power Outlet Panel with a 20, 30, and 50-Amp Receptacle Installed, Unmetered

I had to have the electrical panel redone a bit to add in space for a 100A breaker for the panel. Now i can have my own mini- RV resort next to my house.
Redoing part of the electrical panel to make space, adding in a whole house surge suppressor, and RV panel install and inspection was $670 labor + parts (about 4 hrs for electrician). The new RV panel was $150.

BTW- some jurisdictions now interpret that RV panels have to have GFCI breakers. Just FYI- its a vague interepretation of the NEC.

The enclosure(s) are to keep the wire from being exposed. The new box should be wired directly to the panel. No mine isn’t perfect either but would be a bigger job to fix.

Well the main panel is inside the garage, box mounted next to panel and the romex is not exposed to elements. If yours isn’t perfect then why comment like that on mine?

Happy Camping ⛺️
