Don’t worry full-timers, we love you too! But you have to admit, there are some benefits to stick and brick homes. Some you may even miss. We know the awesome benefits of the full-time life, with the ability to get new neighbors and see new places at the drop of a hat. It’ll be fun when I can retire and do that too. In the meantime, I’m going to enjoy the extra space while I can.

Benefits of Plugging the RV In

It’s really nice to be able to plug your RV into an electrical system while it is in storage or between uses.

First, it’ll keep your batteries charged up between uses. You won’t ever have to come out to the RV after a period of non-use to find out it won’t crank because the batteries are dead. Because that would be a horrible way to start a weekend football road trip.

Second, you can keep your fridge running between uses. I turn my fridge and freezer to the warmest settings that are still on. By keeping the fridge running, you don’t have to worry about mold growing while you aren’t using it. And during football season, when you are using the RV every weekend, you don’t have to unpack all the non-perishable stuff. You can treat the RV fridge as your extended beer fridge! And the fridge will be nice and cool when you pack it on Thursday or Friday for the weekend tailgate (which means a lower risk of food poisoning, another way to ruin a great weekend of RV tailgating!) All this without using up the propane in your tank!

Third, with the RV plugged in, you can run things like the ultrasonic pest repellent that I use to keep ants, mice, and other critters away from the RV. It takes power and again, if you are plugged in, it won’t drain your batteries. You can also run a small dehumidifier. The electric dehumidifiers seem to work much better than the bucket of Damp Rid. In the winter when the temperatures are below freezing, I’ve used electric space heaters to prevent the pipes from freezing up.

Yes, a word to the wise if you are using the electric dehumidifiers or space heaters: keep them away from flammable objects like curtains, carpets and sofas. They do pose a certain risk so make sure all the appliances are in good repair. And away from water sources that could cause them to short-circuit. It is also wise to plug these into the ground fault protected outlets in either the kitchen or the bathroom in case something does go wrong. It’s not a guarantee but does reduce the risk.

Finally, when you are working on your RV, it’s great to have power. Power tools require, well, power. Sure, battery-powered tools are awesome but if you are doing a large project, the battery will wear out. And if you are working in the RV during summer, you’ll want some fans and maybe even the air conditioner. Or if you want to wait until night time, you’ll probably want to use lights and all that jazz! Wouldn’t it be awesome if you didn’t have to use the generator for this?

Thus, you need to be able to hook up to your home electric.

How to Plug In the RV to Home Electric

Guide to plugging your RV into your home electrical system. Keep RV batteries charged between trips!You can go the expensive way: have an electrician come out and wire a plug for your RV, either 30 amp or 50 amp service. If you go this way, it’ll be like sitting at the campground with full service. You can run everything in your RV all at once, including air conditioners.

Or you can go the cheaper way. It’s not as effective because you’ll be using your home’s 120 volt AC system, not the RV’s 14 volt DC system. You’ll have to convert it from your 30 or 50 amp service to the 15 amp service. Then you can plug it directly to the standard three prong plug in your garage.

For 30 amp RVs, you’ll need: 30a female to 15a male. Remove the 30 amp plug from the generator plug, like you would at an RV campground. Then plug it into this adapter. Then you can plug the adapter into your heavy duty outdoor extension cord.

For 50 amp RVs, you’ll need: 50a female to 30a male and then the 30a female to 15a male. Remove the 50 amp plug from the generator plug, like you would at an RV campground. Then plug it into the first adapter (50a female to 30a male). This then gets plugged into the second adapter (30a female to 15a male) which together you can then plug the adapter into your heavy duty outdoor extension cord.

Limits on the Appliances You Can Use

Because of the smaller amp service, you probably won’t be able to run your RV air conditioner. In fact, when I come in from a roadtrip and plug in, if I have forgotten to turn off the A/C first, it will trip the circuit in the home’s electrical panel. So make sure you know where the circuit panel is. Because you will forget.

Microwaves and hair dryers are also going to be iffy on whether you can run them. Best case, go inside your home to use those appliances. If you need the hair dryer for some kind of repair work on the RV, run an extension cord from a different circuit out to the RV.

A different circuit is important. Don’t try running too much from one circuit – you might as well be using everything plugged into the RV. You will trip the breaker. Trust me.

The Adapter and Cord Connections

I prefer the dog-bone adapters rather than the simple plug adapters. In the typically limited space at the generator plug, you don’t want to be stacking up adapters with no room to go. It’s hard enough getting your hands in there to pull the plugs out, don’t be limiting your space even more.

Once you have all the dog-bone adapters setup, try to put all the connections inside the RV power cubby. Try not to expose the connections to the elements to help reduce the risk of damage from water.

Also if possible, use a plug in your garage, not an outdoor plug. Again, keep the connections out of the elements as much as you can. You will reduce the risk of fire by keeping the connections protected.

Heavy Duty Outdoor Extension Cord

I recommend that you use a heavy duty outdoor extension cord. First, it will be exposed to the elements. So make sure that it is in good repair. New is preferable. (Did you know that extension cords have a limited lifespan?) Indoor extension cords are not suitable for outdoor use or exposure to the elements. They are also typically not suitable for the larger loads that you may put on the cord with it plugged into the RV. Get yourself that heavy duty outdoor extension cord for safety!

Monitor Your RV

Don’t ignore your RV. It’s easy to do when you aren’t using it every week during the off-season. You should check in at least weekly to make sure that everything is working appropriately. The dehumidifier may need emptying. Check that there is no standing water or leaks, a problem that will be made worse by electricity. While you are at it, inspect that extension cord to make sure that there is no damage to it – cars running over it, critters eating at the cord, or even a lawnmower chopping it up. All can lead to damage to your home or your RV.

Power Your RV with Home Electric

Plug in your RV at home even without a dedicated 30 amp or 50 amp plug. See, it wasn’t that hard to plug in your RV to your home electric system. With a few precautions, you don’t have to worry so much about fire. And you can reduce other problems from not having electrical hookups. No mold, freezing pipes, or dead batteries. Awesome sauce!

PS It’s a good idea to throw all the adapters into the RV before you leave on a road trip! You never know when a campground isn’t going to have the right electrical service for your RV. While you may not be able to run all the systems in your RV (most notably, the air conditioner), having limited electrical can be the difference between being able to stop and having to continue on. Or use the generator. Which may not be allowed after hours. Be prepared with all the cool adapters!

    Is it okay to use an extension cord splitter to connect the extension cord from the RV to more than one circuit in the house or should extra extension cords be used?

    • Kimberly says:

      Brenda,

      I really recommend that you not use splitters on extension cords. Most RVs, especially newer RVs, are going to be running up to the limits on most home electrical systems. Using splitters lets you put other things on the same circuit and will likely lead to the breaker tripping. Or worse – the cords heating up and starting a fire or other damage to your home or to your RV. That’s the most important thing here – safety and no fires!

      If you can, you can run separate extension cords to the RV to help reduce the load on any one circuit. For example, right now with the cold spell coming through much of the country, many people will be running electric heaters in the RV. If you can run a separate extension cord, from a different circuit, to the RV just to run the heater, that would be wise. The regular cord can run the battery chargers, the fridge, etc.

      Hope that makes sense.

    I just brought home our first ravel trailer last week. I had it plugged in to the outside outlets of the house just the way you said above. Only used the lights the few times I went in there over the past week to measure, etc, for things I need to get. Went in there today, no lights were working. Nothing. I am new to all this and something like this happening was what i was afraid of by purchasing in the winter and having no experience whatsover. What have I done wrong? what could be the problem? I was in there 2 days ago and all was fine.

    • Kimberly says:

      Christy, congrats on the new travel trailer! I’m sure that you are learning a lot of new things right now and all of this is kind of crazy to you. I know it was when I bought my first RV. The good news is that it gets better, things slow down as you get the hang of it all.

      Is anything working in the RV? For example, is the fridge working? Water pump? Fans? Try a few different things to try to isolate the problem.

      If other things are working, then it is likely that there is something wrong with the lighting system – check to see if you tripped a breaker inside the trailer.

      If nothing is working, then we need to figure out if it is the house or the trailer that is causing the problem. First, check your breaker box in your house. Is the breaker on or did it get flipped at some point? If no power is getting to your trailer, then it won’t be charging the batteries and they will slowly drain (or quickly, if you have a lot of things running in the trailer).

      Second, check the outlet that you have the trailer plugged in to. Does a clock radio work on the outlet? For whatever reason, sometimes people will disable outside plugs – this was a problem on a rental house that I lived in a few years back.

      If the breaker is good and the outlet works, then let’s start looking inside the trailer.

      Do you have an automatic transfer switch on your trailer? When I plug in my RV, I can hear it switch from battery power to shore power or to the generator. It usually takes a couple of seconds after I plug it in but not too long. This is to help guard against power surges. Sometimes, the ATS (automatic transfer switch) is bad, even on a new trailer. Do note that some of them do not make a noise when they changeover. If you turn on the generator, will the lights work? Any other systems? If you can get power with the generator, it is likely that this switch is the problem.

      Good luck! Please let us know if you get the lights working again. If not, we can keep brainstorming what could be wrong.

    Hello! We just bought a 2018 Carado Banff on a Dodge Promaster Van chassis with 2300 miles and very little coach use. It has dual lithium batteries, solar and the VoltStart system. We brought it home yesterday and connected it to a 110 receptacle as suggested from the dealer. Our concern is that it makes a loud, high pitched ringing noise, like a ringing in the ears after a loud noise, inside the coach. It does this after several minutes of being connected to 110 power. Both lithium battery switches are on, the inverter switch is on, and the battery disconnect is on (lights and appliances are operational). It seems like it begins doing this once the batteries get to 13.1 or 13.2 charge. It’s quite loud inside the coach and we could not hang out, let alone sleep, with that sound. I then disconnected it from power, but sound persisted. Then switched off battery disconnect, sound persisted. Switched off inverter, sound persisted. Switched off battery 1, sound persisted. Switched off battery 2, and it finally stopped. So I switched batteries back on and reset them, switched on the inverter, and switched on the disconnect. Checked lights and heater, tv, etc. Then turned off all appliances but kept disconnect, inverter and batteries on. Reconnected to 119 power and it was silent. So we went in the house and thought it was ok. But 20 minutes later it was whining again. I don’t believe it is a fan of any sort as it is a very high pitch noise as stated above.

    Any ideas?? This is our first RV and are clueless about this. Thanks for your help!!

    • Kimberly says:

      Jennifer, I’d be concerned about your converter/charger – this is what takes the power from the batteries to run your 12V systems and when plugged in, runs those systems and charges the batteries. See if you can find your converter and see if this is what is producing the noise. You won’t want to do any repairs on the converter yourself. You’ll need an RV electrical mechanic to take a look at it. Since you just bought it, perhaps the dealer’s shop can help you here.
