RV Outlet Box

I'm a virgin to the forum but like what I've seen.

I want to install a Connecticut Electric CESMPSC75GRHR which has a 2 110, 30 amp, and 50 amp RV outlets. The location is on the opposite side of our home from the 200 amp main panel in a protected location under a covered patio.

Since I'm doing this, and to get maximum flexibility should I need something in the future, I'm looking at putting in a 100 amp sub panel about 90 ft from the main and run the final 6 ft to the RV panel from that. What gauge and type wire for each run?

My plan is to run from the main 15ft through new 2 inch sch 40, through the attic (no Sch 40 there) and then down 8 feet of 2 inch sch 40 to the sub panel and more 2 inch sch 40 to the RV panel.

Hope I didn't leave anything out.

Thanks in advance,
Joel

Welcome to the best DIY forum on the Internet.

Joel is a good name, it's my name as well.

We need a bit more information on your proposed project. I'm going to start by asking you to state your level of proficiency when doing electrical work. Since you stated "110" volts I am assuming that your level is fairly low as the standard residential voltages in the US have been 120 and 240 for at least fifty years.

No matter, this is a DIY site and we CAN help you to educate yourself. Installing a sub-panel and this RV panel is certainly a DIY project but you need a foundation first. Unless you already have a copy I strongly suggest that you buy a copy of Wiring Simplified and read it cover to cover. In addition, borrowing a few DIY type electrical books from the local library will give you a good background on doing the actual work. I recommend Wiring Simplified because it has been in continuous print for over fifty years and is revised every three years to coincide with the revisions to the National Electrical Code (NEC). Wiring Simplified will not only tell you how to do it but WHY it is done in that manner. It is written for the lay person and so is easy to read. The cost is about ten dollars depending on where you buy it. My Home Depot sells it for $6.95 as I recall. It is found in most home improvement mega-marts in the electrical aisles rather than the books and magazines section. Many neighborhood hardware stores also sell it and it is readily available from several on-line book sellers.

So tell me, what electrical projects have you done?

Hello Joel,
I suppose I know enough to be dangerous. The comment on 110 is more a reflection of my age than ignorance, I hope. My knowledge is rudimentary self taught. I've done alot of home stuff installing new plugs, rewiring lighting, installed a manual crossover switch with generator feed, easy stuff. I'll get the book and read. It sounds very familiar, I may have read it years ago.

How old are you? I'll be 65 next month and I've been using 120/240 volts since my teens.

Is this the panel you want to use? http://www.amazon.com/Connecticut-El.../dp/B001FCWMRG

It should be a pretty easy job depending on how your house is constructed between the service panel and the location for the proposed sub-panel and then the RV panel. Maybe a few pictures of the service panel and anything you might think of as an obstacle would help me or one of the electricians make some suggestions.

As a new member you may need to have the pictures okayed by a moderator. Uploading to a photo hosting site may be easier because sometimes the forum software likes to turn the pictures sideways.

"220, 221, whatever it takes." - Mr. Mom

Conduit is required to be continuous for the entire run if using individual wires. Otherwise you would sleeve cable in the PVC for protection.

Are you planning on needing both RV outlets at the same time? If not you can get away with much smaller cables.

IIRC 2014 code requires that if there is a 50 amp RV receptacle, a 30 amp is also required to be provided. They should all come in the same enclosure so it likely still only needs a single 50 amp feed.

As a long-time RVer, I see absolutely no logic to that requirement. Nor have I ever seen a campground that was so equipped. Can't help but wonder what the point is.

The point would be to discourage someone that has a 30 ampere inlet to their RV from using a "cheater" to plug into a 50 ampere receptacle.

Furd gets the gold star!

@md2lgyk - That is because it didn't go into effect until 2014, and not all states follow the 2014 NEC.
