Electrical System Design

Most RV’s and camper trailers utilize the same types of electrical systems as those used for an average small home. But in addition to the 110 volt electrical supply, there may also be lights, fans, a refrigerator, or other electrical devices which use a 12 volt supply, like that of a car or truck.

A 12-volt DC system powers the RV refrigerator to keep food cold while the RV or camper trailer is moving from place to place. The same goes for the lights and fans. It also keeps the on-board batteries fully charged. This system relies on the 110-volt AC electrical power supply for amperage.

It is possible to pull a 12-volt power supply from the RV or camper trailer's electrical system or 110-volt campsite power supply. Then the 110-volt supply can be stepped down to 12 volts after it is run through a power converter and to a particular appliance.

Rewiring a Classic RV

Most of RV systems will switch from the 110-volt AC to the 12 volt DC supply automatically when there is a power interruption. These two electrical systems are treated independently from each other when diagnosing electrical problems, except for determining power to the converter. This translates to:

  • 110 volt power-- > converter-- > 12 volt power-- > 12 volt breaker box -- > refrigerator or lights

As in a home, the 12-volt system has its own set of breakers to control each circuit. The lights, fans, or refrigerator may each be on their own circuits, depending on the amperage required. If the converter is supplying 12 volts to the breaker panel and the breakers test positive for voltage, this leaves the wiring or the particular appliance at fault.

Essential Tools and Resources

  • If you are not familiar with electrical wiring or troubleshooting electrical systems there are some very good books available to help you understand and repair common RV electrical problems. I would recommend RV Electrical Systems: A Basic Guide to Troubleshooting, Repairing and Improvement to any novice and experienced electrician alike. It will be an enormous aid to understanding RV electrical systems.
  • Another must for tracing down electrical problems is a voltage meter. This handy tool will allow you to check the circuits for continuity and for the correct voltage required for each breaker. A simple test light can be used but will not test for broken circuits caused by bad wiring or other electrical problems. Both of these tools are inexpensive to own and will more than pay for themselves over time. The voltage meter can be used for home electrical problems as well as any other electrical related problem. Both are offered on this page for a reasonable price.

Troubleshooting Common 110-Volt Problems

  • The 110 volt outlets used in some RVs and camper trailers are prone to shorts because of the way they are installed. Some are merely clipped onto the wiring by cutting into the wires. These types are notorious for not working correctly. Replace these types of outlets with standard house types to put and end to loose connections. Since some of the walls are so thin, a smaller receptacle box may be required for the outlet to fit flush in the walls.
  • Ground fault interrupter outlets are another common cause of electrical problems. These are located in places where a possibility exists of someone touching them with wet hands. They automatically break the circuit when moisture comes in contact with the outlet to prevent shock to the person touching them. A simple reset button must be pressed for the circuit to once again be completed. On occasion they will need to be replaced or the other outlets on the line will not work either. Pay close attention to the instructions when replacing these GFIs.
  • In older RVs and camper trailers you may still find fuses instead of circuit breakers. Since the advent of many new electrical devices, these older fuse systems may not provide enough amperage to handle a microwave or other high amp appliance without blowing a fuse or kicking a breaker. Simply replacing the fuse or breaker with a higher amp substitute may be all that’s required. Replacement of the entire breaker box may be the only option remaining if this doesn’t solve the problem.
  • The newer RVs and camper trailers may have two RV A/C rooftop units which require more amperage than the older models to operate without kicking the standard 30-amp power supply used by many campgrounds. Fortunately, many campgrounds and RV parks now provide 50-amp service for these types of units. When making reservations or checking in, be sure to ask about the availability of a 50-amp hook-up if you own a unit with multiple A/C units.

Keeping your electrical systems in good and safe working order insures a trouble free camping trip with no sudden power outages to ruin the trip. Most problems can be repaired easily if you understand how the system works. RV electrical manuals along with a few inexpensive tools are well worth the cost of their purchase.

If you are completely confused by electrical wiring there are also some very good basic books to start you off. It isn’t very hard at all to check electrical circuits, switches or outlets with an inexpensive voltmeter. Just remember, when touching any wires be sure the power to that particular circuit is off. If in doubt, turn off the main breaker or unplug the RV or camper trailer from the power supply. Happy camping!

      Brickz, there should be no problem with running only one wire if the LEDs are grounded to the metal part of the camper.

      Restoring a vintage camper and adding 12 volt wiring for interior LED lights. can I use chassis for ground and run only a single wire with +12 V to fixtures or should I run second ground wire to all fixtures. Trailer lights are all grounded to chassis. Any issue with doing same for separate 12V system?

      Mary, you don't need a battery for your receptacles to work. Unless you have at least a 30 amp breaker you cannot run everything and the AC at the same time. Your lights and recepts should work on a 15 or 20 amp breaker though.

      Ethan, check the negative battery cable ground where it attaches to the steel frame of the camper. It may be loose or corroded even though it doesn't appear to be.

      Hi Randy,

      I have power to everything when plugged in. However, unplugged, there is no power. I put a new battery in...no power. I changed the in-line fuses (from battery to camper)…. no power. I re-ground the battery to camper frame...no power. I plugged the camper in and disconnected the battery....Power to everything. Every time I turned another light on, I could hear the cooling fan turn faster. All fuses and 120v breakers are normal and all wires seem fine. What can be the problem? Thanks in advance!

      Tom. apparently you have a short somewhere in the 110 volt system. Check the main ground in the power panel to be sure it hasn't vibrated loose during transit. You might also turn the breakers off one at a time to see if one of the other circuits is causing the problem.

      John, have you checked the main battery ground cable yet? This cable connects to the steel frame of the camper and is often the culprit in the 12 volt DC system. This connection should be cleaned often even if it doesn't appear to be loose or corroded.

      If this doesn't solve the problem,then connect a good battery charger up and if everything works as it normally does, then yes, your coverter may need replacing.

      Randy:

      I have a Parallax 7155 55 amp Power Converter in my 2011 travel trailer that is giving me the following results:

      With 120 ac hooked up and main breaker ON I get 5.51v DC at the output blue & white wires, & about 7v DC at the 30 amp fuse slots.

      Turn the breaker off, removing AC power, and the DC voltage at the 30 amp fuse goes to battery voltage (12.7).

      Battery is not being charged and when Battery is disconnected with AC hooked up, none of the DC powered equipment (lights, pump, slide, etc) will work.

      Would just like to confirm that the Converter is in fact bad before shelling out $170.

      Thx, John

      Joe, start by checking the 110 volt power panel for breakers possibly ruined by the mistake. When you get power to the main you can check the other breakers and appliances for damage. If you need more help please ask.

      Denver, believe it or not I get this problem often. You'll need to start at the power panel and check all the breakers, especially the main. You may get lucky and not have to replace the control boards on the AC and H/W heater. The converter may be okay, but you can tell when you get power to the 110 volt panel again. Let me know if you need more info.

      Corey, I have no info for the wiring diagram, but you should be able to find it online. As far as the fridge is concerned, check the exhaust vent as any wasp nest or blockage will prevent the fridge from working. Also, the fridge won't work if the camper isn't level. You can also check the electric element on the fridge to see if power is getting to it or if it's bad. Good luck!

Any ideas would be great. Im fixing that to sell because i bought a 2008 Trail-Lite. It has a Norcold refridgerator in it that does not work. It is Model # N512. The previous owners never used it. Power comes on to the panel. You can switch it back and forth to gas or electric. I just don't know where to start...

      Recently I hooked up my 2017 Wildwood Xlite travel trailer and I noticed a weird smell from the breaker box. The Power Center box was warm to the touch. The 30/20 breaker on my Power Center were tripped. I flipped it back to on and there was a surge and sparked a small electric fire frying all the wires inside the Power Center and melted the plastic around the Power Center edges. Power to the whole unit went out including the GFI's. Battery power operated the lights, slideout, and thermostat. I purchased a new WFCO 8955 series Power Center, 30 Amp shore power cord, and three knew Murray breakers 30/20, 15/15, and a 15/15. After installing everything to the tee, I've got 120 Volt power coming in on the 30/20 breaker as this is confirmed using a test light and the AC Unit turning on....However, the two 15/15 breakers do not turn on the appliances or other power the slide outs and GFI's. We can't seem to understand why the 15/15 breakers are not working like the 30/20... Possible I need to run a continuity test to make sure the surge didn't burn up the wiring somewhere else?

      Dale, the main ground is where the negative battery cable connects to the steel frame of the camper. This connection needs to be cleaned often both the cable end and the frame. This is a common problem.

      Bob, if you have a wall mount thermostat, then yes, you need the 12 volt system to also power the lights and the H/W heater thermostat. You may get by without a battery if the converter powers these items okay by itself.

      I have suddenly lost my 112 volt system! It was working fine two weeks ago. The inline fuse from the battery is not burn. Hooking up to the generator, everything works, so i am thinking it is not the converter. Hooking up to the truck, nothing works again. I did notice a very faint glow from the pump switch on the monitor late at night when there was no lights on. So, would i be correct in thinking it is a grounding issue and the next question is where would they ground the 12v system? I replaced the ground connection from the converter already.

      Melissa, check the battery ground cable where it attaches to the steel frame of the camper. This connection needs to be very clean in order for the 12 volt system to work properly.

      Also, you may have a breaker or fuse inline on the positive battery cable leading back to the 12 volt converter or 12 volt power panel. Not all campers have this, but you can check for sure.

      Michael, when connected to shore power the converter is producing a 12 volt DC charge to the battery which power the running lights and tail lights.

      There's probably a bad ground somewhere, and more than likely, it's the battery ground cable where it attaches to the steel frame of the camper. This is the main ground for the 12 volt system and all sorts of weird stuff happens on the 12 volt system when this ground is corroded or loose.

      Try cleaning this connection well and see if this fixes the problem. Good luck!

I unhooked the battery and plugged in with 30 amp, and the tail lights came on again. Now whenever the battery is connected or the trailer is plugged in to electricity, the tail lights and running lights are on. How can 120 volts power the tail lights? Thanks!

      I have checked the ground with a multimeter and is good. I tried to find an inline fuse but the pos cable goes into the floor and im not sure where it leads to. I have an converter with a red cable that does not have power when hooked up to only batteries and also have a red cable going back to fuse panel. Which one is from batteries and where are some likely spots for them to hide the inline fuse? Thank you for your help.

      Chad, there are two things you need to check first. There is a negative battery cable connected to the steel frame of the camper. Make sure the connection is clean on both the cable end and were it contacts the frame.

      Look for a fuse/breaker inline on the positive battery cable leading back to the converter or power panel. You may have tripped the breaker/fuse. Hope this helps!

      Megan, if you have any GFIC outlets, check them to see if they will reset or if they have power going to them. These outlets, usually in the bath and kitchen area, will go bad and cause the other regular outlets on the same circuit not to work either.

      Let me know if this doesn't work and we'll go from there.

      Hey, Randy me and my husband were camping last week and the camper would not switch over from the battery to electric. We called camping world and they told us we need to buy a new converter so we bought that and put it on and it fixed it but the bedroom outlets do not work and our refrigerator will not switch over from propane to electric and we have no idea what to do we have checked the breaker and the outlet for it and they are fine. We have a 2017 27 foot mallard and are 20 days over the warranty. Its a 30 amp camper or atleast thats what we have used the last year and never had any problems. Any advice or suggestions would be greatly appreciated thank you in advance!!

      2006 nomad camper. The 12v lights stay dim an the battery won't stay charged. The water will only stay hot for a couple seconds. Do the lights always run on 12v even f you you plugged in to 110? There is only one light in the camper that will work with 110. Could it possibly be a converter problem? We are hooked to 30 amp power. Thank you for any help.

      Everette, there may be a plug which has come loose when the slide-out was activated either n or out. There's usually an access panel where you can see the wiring connections located near on in the slide-out.

      Patrick, as long as they use a regular 110 volt outlet, any micro will work.

      Hey Randy finally got converter changed out everything working great, except microwave, are they standard units as long as we can find the same size or are these built specifically for campers?

      Jim, have you checked the outlets for the fridge and microwave yet? Is there a GFCI outlet in the kitchen with a reset button? If so, it may be bad and on the same circuit as the fridge and micro.

      I have a 1996 Kit 24 ET. When I moved the trailer and plugged into a 110 source, I heard a pop, and now the refrigerator and microwave won't work. Any Ideas? All the breakers are on unless there is another box somewhere.

      Kirsten, this sounds more like a bad gen/shore switch. If the battery is charging the converter is not the problem.

      We have an Onan generator that has been working fine both while driving and parked when we have place to plug-in. However, we just stopped this evening and can not seem to get it to run. We also have an external generator, so started that up and still no power coming to motor home. But there seems to be juice to the plugs. Living tonight on battery. Thinking maybe converter, but not sure where to start eliminating problems. Did notice that the GFCI in bathroom will not reset. Any thoughts? We are in middle of long road trip and growing frustrated...

      Randy, I found the problem. I had a broken neutral coming in where I replaced the inlet power plug on the outside of the rv. I thank you so very much for your help. You are a blessing.

      Rhonda, the AC is not on a DFCI breaker so you may have another problem with the power not getting to the system. If you have power to the panel main and to the other breakers, look for a loose ground in the breaker panel.

      OK, will do. The breakers are not GFCI breakers. Does the 20amp a/c unit also depend on these 15a GFCI receptacles? Sry, for all the questions and really appreciate your help. Thank you.

      Rhonda, I don't know if your 110 volt breaker panel utilizes GFCI breakers, but they should be marked as such if so. No Need to remove the panel. Try changing the GFIC outlets first. This may not be the problem but you'll find out for sure.

      Thank for responding. Is this GFIC located beside or behind the breaker panel? Is there a main GFIC or are we talking about the individual plugs? Do I need to take the breaker panel out to find this GFIC? Again, I appreciate your help, thanks.

      Hello, need some help please. I have a 2004 Rockwood by Forest River. I experienced circuit breakers tripping and they were really hot. The converter was very hot (think the fan was bad). I replaced the converter and put in a new Battery (RV Deep Cycle). I notice the hot leg on the power cord was fried on both ends. So I replaced the 30a box with an RV box and bought a new power cord. My problem is now I have 110v at the breakers but nothing 110v has power. The 12v system works fine, but no 110v at receptacles. Have reset GFCI rec. Not sure where to go from here...

      John, the microwave is probably toast now. It received twice the voltage required to operate it. The control board is a goner! Sorry!

      Baallen, yes it could have damaged your converter as it received double the required voltage.

      Patrick, as long as it is 110-120 volts input it should be fine. It's usually better to have more amperage than needed.

      Hey Randy I figured out I fried the converter, now I'm trying to figure out if I can replace it with Intella power 9200, it's a 45 amp system and my camper is 30 amp, think it will work?

      Landon, I've had this same question from other campers with a GFIC at home which trips when the camper is plugged in.

      I think it may be due to the way a camper is grounded which makes the GFIC trip, especially if the GFIC doesn't have the necessary amps to supply everything needed.

      I haven't heard back from any of those with a similar problem so It's a bit of a puzzle at this time. Perhaps you can solve this mystery, Landon. I have no way to check for this problem as I cannot duplicate it.

      I'd be pleased--and so would others I suspect--if you let me know what you find.

      I have 1999 Skyline Nomad. Everything worked great last fall when i winterized it for the winter.

      This spring I plugged it in to the house and tripped the gfi on the house right away.

      After plugging it into a non gif outlet everything will work.

      I did some testing and have it narrowed down to the water heater and the fridge. Even after I turn off the switch to the water heater the gif still trips with the fridge. Yet the fridge will run on the battery and gas. Any thoughts on what could be the issue?

      I'm thinking the water heater issue is the heating element.

      Andrew, the fridge and H/W heater have a thermostat which operates on the 12 volt system. Check the battery negative cable where it attaches to the steel frame of the camper. A bad connection here will cause this problem.

      Also check the positive cable of an in-line breaker box or relay. Not all campers have this relay.

      we have a 2006 puma I have it plug in to 30 amp 110 I cant seen to fig out how to get the fridge microwave or the water heater to work the fridge will not cool on gas or electric the micro wave is just blank I have checked all the breaker and they are all in the on position fuse are all good I am new to this r v repair as this is my step daughter camper and I told her that I would help to try to get things in good operating order but we have no manuals or literature on how to repair or operate things like the fridge or hot water heater. I know where the micro wave plugs in we don't have any voltage.so any help would be appreciated Thanks Andrew

      Patrick, try turning off all of the 11o volt breakers excluding the main and see if it still trips.

      Patrick, have you tried resetting the breaker with the camper unplugged from power? If it still won't reset the breaker is indeed bad.

      Patrick, be sure the negative battery cable is clean where it attaches to the steel frame of the camper. A bad connection here can cause all sorts of problems with the 12 volt system.

      If the 12 volt converter is furnishing enough power with the battery it should still work fine, but it's better to have the extra amperage a battery provides.

      We have a 33' fifth wheel sandpiper o6 I believe, being plugged in it doesn't charge the battery, also should it work being plugged in and no battery?

      I have a 1986 33ft Chevy Southwind moterhome that smashed into a redwood tree & the right rear brake light wire's were all severed. Do I just reconnect each wire to it's matching wire or do I need any special kit to replace it

      Rob, check the negative battery cable where it attaches to the steel frame of the camper. A rusty or corroded connection here will cause all sorts of weird electrical problems.

      Also, some campers have a fuse/relay on the positive battery cable leading back to the converter or power panel. Not all have them but you may check for it. Good luck!
