Installing Outlet for our RV - 30 or 50 amp? May 15, 2021, 11:13:24 pm I have an electrician coming to install an outlet for our RV so we can plug it in at home.Toying with the idea of installing a 50 amp outlet so we can host larger rigs as well as plugging in our Lazy Daze.Would there be a downside to leaving our rig plugged in to a 50 amp outlet using a dogbone and surge protector?Is there a reason I should stick with a 30 amp outlet? Am I correct that this is a 120v outlet?Any and all advice / opinions would be much appreciated ☺️
Re: Installing Outlet for our RV - 30 or 50 amp? Reply #1 – May 15, 2021, 11:28:01 pm I would do a NEMA 14-50 (50-AMP) if you can, if only because it's also becoming a standard outlet for electric car chargers. Those are very common for electricians to install these days. The RV-30AMP (called a TT-30) will probably cost less, but be aware that some electricians aren't familiar with them. When they hear 30-AMP, they think of a 30-AMP 240v outlet instead of the RV 30-AMP 120v outlet. Be sure your electrician knows exactly what you're looking for.https://www.rvtravel.com/a-common-expensive-mistake-when-installing-30-amp-rv-outlet-at-home/No downside that I know of to plugging a 30AMP rig into a 14-50 long term. Just use high quality adapters. Rich 2 Likes
Re: Installing Outlet for our RV - 30 or 50 amp? Reply #2 – May 16, 2021, 12:10:35 am I would definitely install a 50-AMP RV circuit, because you can always go down in power (the reverse is not true). 1 Likes
Re: Installing Outlet for our RV - 30 or 50 amp? Reply #3 – May 16, 2021, 01:55:36 am Assuming your electrical can support a 50-amp, 2-phase circuit, I would install both a 30-amp and a 50-amp plug, so there is no need for an adaptor.Larry 2 Likes

While some don't want the extra expense, I believe my comments from 2020 are even more valid now. Install 30amp or 50amp at home?? A likely box like a campground would have: Siemens TL137US Talon Temporary Power Outlet Panel with a 20, 30, and 50-Amp...

Re: Installing Outlet for our RV - 30 or 50 amp? Reply #6 – May 16, 2021, 05:48:29 pm After reading everyone's helpful suggestions (thank you!), decided we'd go with a compromise.I've asked the electrician to wire for 50 amps (for a future upgrade), but configure it for 30 amps,and put in a 30 amp/120v RV outlet (TT-30) and a "regular" 110VAC/20 amp outlet.

Reply #7 – May 16, 2021, 05:52:13 pm Hi Kitty; By the time you've got the wire there, it's just another $50 to have all three types of plugs and breakers already in the box. The extra expense on the house side is more breakers in the house panel. RonB 1 Likes

Plugging the rig to a 50A with adapter, your rig is protected by the 30A circuit breaker in the converter.Steve 1 Likes

Reply #9 – May 16, 2021, 06:13:24 pm Whether you put in a 30A or a 50A service, I highly recommend also having breakers at the outlet panel, unless the main panel is very close by. I don't like plugging/unplugging my shore power cord with a live outlet and it is easier to turn off power if working on the coach's electrical system.Art 3 Likes
Re: Installing Outlet for our RV - 30 or 50 amp? Reply #10 – May 16, 2021, 06:14:36 pm Looking at our panel, thinking we do have room for all 3 outlets/breakers. Will check with the electrician to see what he thinks, thanks.Though, right now not sure what I'd do with an "extra" 50 amp outlet.Suppose it might let us host another rig though
Re: Installing Outlet for our RV - 30 or 50 amp? Reply #11 – May 16, 2021, 06:20:19 pm Hadn't thought about having a breaker at the new outlet box. New outlets will be on the opposite side of the wall from the main panel in our garage.Will ponder whether we want to go inside, back outside to plug in, then back out again.QuoteWhether you put in a 30A or a 50A service, I highly recommend also having breakers at the outlet panel, unless the main panel is very close by.

Re: Installing Outlet for our RV - 30 or 50 amp? Reply #12 – May 16, 2021, 08:40:56 pm Hi Kitty; If you have breakers in your house panel and the plug is outside on the wall of your house you probably don't 'need' another set of breakers. If however you are locating a remote pedestal outside to near where another, or your own rig may be parked, you would want remote breaker(s) at that pedestal. I would still want steel conduit, at least 18" deep. Common practice is to put a piece of orange painted wood over the top of the conduit, and a sign at both ends announcing an under ground electrical cable. Those backhoes are rough on electrical and gas lines. My friend with a ranch in rural San Diego has his electric service covered with concrete and when possible 4' deep. RonB

If you just put in 1 50 you may not be able to use your 30 at the same time, you could exceed the 50amps. If you want to use both I would run 240v out there and have each outlet on a different leg, a120v 30a on one phase and a 120v 50a on the other.

The former comes from a 50 A double-slot breaker in the load center and can supply 12,000 Watts, the latter from a siingle-slot 30 A breaker, and can supply 3600 Watts.Steve 1 Likes
Re: Installing Outlet for our RV - 30 or 50 amp? Reply #15 – May 21, 2021, 02:52:48 pm We're now the owners of a 30 amp RV outlet on a 30 amp breaker and an extra household outlet on it's own breaker. Directly on the other side of the main box in the garage, so a very short run.Electrician ran the wires for 50 amps to the 30 amp outlet, so we can simply replace the breaker and outlet box if we ever see the need for an upgrade to 50 amps.Since we got her, we've kept our gal "Serendipity" more than an hour from home so we're more than a little excited to have her right here in the driveway.Thanks for all the advice and wisdom everyone :-) 1 Likes
Re: Installing Outlet for our RV - 30 or 50 amp? Reply #16 – May 21, 2021, 02:54:26 pm Glad you worked something out. Having RV power at home is very convenient.FWIW - that looks like a 30-AMP 240V clothes dryer outlet (called a NEMA 14-30). It's not what you would find at a 30-AMP RV pedestal (120V NEMA TT-30). Hopefully that's what you were expecting and the electrician gave some advice on the correct type of adapter to use. Rich 2 Likes
