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!

      Jim, normally if you have the batteries off, your converter won't keep the 12 volt system properly powered. Your system may be different though.

      Hi, Randy

      So, I thought the problem was fixed. But last night, while connected to 30 amp power, with the batteries turned off, we lost all electric power. I then, not knowing what to do, flipped the battery switch back on, and everything then worked. I normally have the batteries off when connected to power. Any thoughts?

      I have a 2004 Fleetwood sequoia pop-up camper.Both lights at the bunk-end work but the 2 lights above the gallery and shower do not work. Checked all of the fuses and kill switch and all were ok. Took out the 2 switches that control the bunk-end and gallery lights and have 12 volts on the black and yellow that go to both switches. Bypassed the switch going to the gallery lights by hooking the 2 wires together but no luck. Help!

      Anissa, if you're replacing all of the 110 volt ac wiring, you can use 110 v lights instead of the 12 volt lights many campers use for camping unconnected to shore power.

      I assume you still have the H/W heater left from the previous owner and it will require 12 volts f0r the thermostat. You may need to order a basic RV wiring guide to help in your rebuild.

      Let me know if you run into a problem.

      Hey Randy,

      Sorry to sound like a complete idiot when asking this question but here it goes. I purchased a 1998 Rockwood T2305 camper for $300.00 with the intentions of complete remodel (needed due to the last owners) they stripped all the copper out of the camper. So I totally gutted the camper out. Even though they left the converter all the wires were disconnected. Any help from start of what I need to finish would be greatly appreciated.

      Nathan, you can install a GFCI, if you feel better about it, but many campsites already use some sort of GFCI on the shore power connection.

      Hi Randy,

      So I've got a '61 Airstream Bambi. The original power converter failed and I have replaced it with the PD9245, and a 12volt fuse block as both of those functions were performed by the original converter.

      I've also had to replace the shore plug due to corrosion and such. I am wondering if I should/could install a GFCI outlet where the 110V comes into the trailer?

      On my set up the 110V power from the shore plug feeds into the backside of an outlet where the converter/charger plugs in. The 110V that feeds the house circuit breaker connects through the backside of the outlet. So for surge safety, or any other reason should I do a GFCI there? If so should I ground it to the trailer's frame?

      Thanks in advance!

      Jim, first check the main 12 volt DC ground as it may be loose or corroded. This is the negative battery cable end where it attaches to the steel frame of the camper.

      If this isn't the problem, then check the voltage at the battery. If the converter is good you'll get a reading of at least 13 volts at the battery.

      Both the fridge and AC thermostats use the 12 volt system to operate in most cases.

      Michele, check the main ground which is the negative battery cable end where it attaches to the steel frame of the camper.

      Even if this connection looks good, it may be corroded or loose. Make sure it's clean and tight. Also. check for a relay/fuse on the positive battery connection leading back to the converter. Not all campers have this feature.

      Barb, check the main 12 volt ground first. It's where the negative battery cable end attaches to the steel frame of the camper. This connection should be clean and tight.

      If this doesn't solve the problem, than connect a good battery charger--at least 20 amps--and if everything works properly the converter is more than likely bad.

      We have a 2019 Jayco Eagle fifth wheel. We have no,lights or air conditioner. It seems like the batteries are not charging even thou we are plugged into 50amp. We are at a camp ground now and can’t get slides in etc.

      we have some areas in RV that the power works just now lights or air conditioners. What could be wrong. It seems like it’s not charging the batteries.

( took stove & sink, heater out.... air conditioning , fridge & micro work on shore power......but someone cut a lot of wires ( propane area, heater, etc... really don’t know where these wires are, but I KNOW we have an alarm going off. Def gonna need a prof electrician. But, my question. Where ( I have looked everywhere! Even called dealer that 1st sold it . No help! ) please , WHERE is the exterior electric/ wire junction to hook into our truck ( Silverado) it is Not where it should be - behind drivers side , just under the overhang. And, how & where do you turn on running lights????? Even if we are connected to our home (a/c power) or battery, they do not come on........ are we missing a “ switch”...?.?. Generic manuals online are No help. Any help , would be soooooo appreciated...... it is a cute little camper. I cannot believe their is very little info on them! ( wiring diagram would be awesome,)

      Don, this may be a converter issue. Check the voltage at the batteries as they should be getting at least 13 volts from the converter.

      If not, try connecting a good charger to the batteries and see if it solves the problem. If so, then the converter may be bad.

      I have a 2006 Forest River Cedar Creek 5th wheel that is connected to Shore power from my shop, which has never had any power issues what so ever. I should mention that I only recently added the 50amp breaker and RV outlet...since plugging the RV in, I have had a good two weeks of good power supply running the AC, fridge, and everything else without issue while a guest was staying in it. one night a couple of days ago, the fridge alarmed and eventually the power to the whole trailer went out (less one outlet that had a very small power draw for wifi) and stayed out. I used a multimeter to try and diagnose the problem and found the shop breaker, outlets, and cords all had good consistent power...the line and load sides of the RV breakers also showed proper voltage but there was still no distribution of power to the trailers outlets, lights or appliances (except the small draw wifi unit). –I will also mention here that the battery disconnect was turned to the off position for shore power and if I turned it on, the entire RV would power up all of the 12VDC fixtures. After diagnosing this problem for almost an entire day, I left the unit and when I went back everything was back up and running...

      In the middle of the night the following day, the power started going down again, (fridge alarming exactly as before) but this time after about 2-3 mins the power seemed to stabilize and everything was fine for the next 30 +/- hours. Then it happened again this morning but has remained off like before... please help...thank you!

      I have a 2006 Calrson toyhauler. Yesterday all of the 110 kitchen associated plugs and the refrig and freezer stopped working. All of the other plugs in the trailer are working on 110. I located and pulled the 12 volt kill switch. The Frig and freezer and ancillary lights now work but none of the plug ins come on. One of those plugs is a GFIC and I can not get it to reset.

      I am not very knowledgeable on electrical for the trailer but have successfully wired a couple of houses with no burn downs. I would think that there should be a circuit breaker box but am unable to locate one and do not have an electrical schismatic.

      Should there be a circuit breaker box with circuit breakers?? Any clue where it might be. I have looked in the side external storage bins but find nothing. Any other guesses as to what my trailer electrical problem might be??

      Thanks

      Hi, Randy: I am brand new to camping and purchased a 2007 Layton travel trailer. The unit was rebuilt. When examining the electrical system, I found a double tapped wire at one breaker (easy fix) and underneath the breaker box anchored to the floor is a 10 terminal bus bar. The bus bar contains two larger black wires (each in its own terminal) and seven white wires jammed into four of the terminals. The remaining four terminals are empty. A couple of questions: is this safe and legal? Why would a bus bar be connected to the floor? Could this be for the 12 volt side? Any advice if corrections are necessary? Many thanks, Tom

      Working on a older bon air tent trailer model# ba1050. Has a Power Dynamics converter in it. Heres whats happening. I plug the 110volt plug into a 20 amp source.Also has a good 12v battery hooked up. Trailer is rated for 15 amp. So when i switch the converter to battery i appear to have lights. But no furnace or fridge. Should be said fridge and furnace are both 12v dc, 110 volt ac and propane. When i switch to the converter setting, the only thing that works are the extra receptacles in the counter designed to plug in house accessories (coffee maker, tv, etc). i pulled the convertor out and tested the wires that are supposed to be producing 12 volts and i get nothing from any of them. There is a white( ground) then a red, black, and two blues coming from the back of the convertor all of which are supposed to be producing 12 volts. All appear to be dead. Check the bus type fuses in the front and they are good. Do you think it needs a new convertor. Just got this trailer and is in good condition other than this electrical issue.

      Pete, I wouldn't think the 12 volt system would affect the 120 volt side, But I've witnessed stranger things. Check the positive battery cable where it attaches to the steel frame of the camper for corrosion and looseness as this is the main ground for the 12 volt system. Let me kow if this doesn't solve the issue.

      I have a 2006 T@b with intermittent issues on both AC and DC. I have checked the power supply on the 110 side and it carries through all the way to the converter. The DC system has not been plugged-in for weeks, and the battery may be bad, but even when connected for hours to the vehicle, I can't get either AC or DC functionality. Could the old battery be impeding the whole system? Do I need to evaluate the converter?

      If this doesn't solve the problem, then connect a good battery charger to the battery(s). If everything works normally, then a new power converter may be in your near future.

      Carmen, first check the main ground for the 12 volt system. this is normally the ground cable on the battery which connects to the steel frame of the camper. This connection needs to be clean and tight, otherwise you'll get all sorts of strange electrical problems.

      If this doesn't help, then connect a good battery charger up--not a trickle type--to the batteries to see if the power converter is working or not.

      David, if you have any GFIC outlets they are prone to going bad and affecting the others connected to it.

      Jim, the waterline you mentioned under the shower may be fro draining the water lined during the winter. Most campers have drains for both hot and cold water lines. Check for such a valve as it may've been left open by the last owner.

      As for the electrical question, I hesitate to give you advice about your particular electrical set up as I'm not familiar as to why there should be 3 different inputs.

      One 30 amp power supply should power everything if you only have one AC unless the other plug provides power to the 2nd AC. If you have an onboard generator, this could account for the other 30 amp input, but this is simply a guess on my part.

      Have a used Teton Homes Grand 5th wheel that I'm trying to figure out a couple of issues with. 1st, when I hook up the water to the "city water", the water flows directly out of a clear PEX pipe right under the indoor shower. I'm thinking when it was winterized, the valve was left open. I can look into this if that is the problem.

      2nd, I'm trying to hook into shore power for electricity. I have a single 30 amp receptacle for the power to plug into (the trailer has 30 amp plugs), but there are 3 different 30 amp plugs, so obviously can't plug all 3 into a single outlet. Right beside the 3 wires, there are 3 empty female 30 amp plugs that seem to be tied together. Should I run one plug to the receptacle for shore power and plug the other 2 into the empty receptacles in the trailer to provide power to all 3? Obviously will not be able to run a lot at one time being only 30 amp, but does my solution sound OK?

      Sam, you're right. Normally the red and black are positive with the white being the ground. Do you get a reading from the wires with the battery disconnected?

      Were the 12 volt items all working before?

      I purchased a used 1984 Terry Taurus 28’ tow behind. It came without a battery. Plugged into 110 volt everything works as it should. I attempted to hook up a 12 volt battery,but I do not get any power from it. I’m not totally sure I have the wires correct. I have three wires. Black white and red. I know the white is ground. The red and black are where my problem is. With both hooked up I should have power in the camper. I don’t. Do you have any idea what I’m missing or what’s wrong? I checked all fuses and they are all fine. Like I said everything works fine plugged in. Thank you.

      Kchristiana, Over time a breaker can become weak after being tripped many times. Try replacing the breaker before doing anything else.

      Sam, try cleaning the negative battery cable where it attaches to the steel frame of the camper. If this connection isn't clean, it will prevent any 12 volt appliance or circuit from working properly as this is the main ground for the 12 volt system.

      Angel, one of the lights in the circuit should be grounded to a metal part of the camper or to a ground wire. If none of the other lights are working, then check the first light for a ground wire, a white wire is normally the ground wire.

      I recently received a 1998 Skyline Layton 3090 travel trailer. It is a standard 30 amp circuit. I replaced the plug for a newer one. This is then plugged into a 30 amp outlet. I have checked the wire ends to make sure they are clean. I have yet to determine why I can't get power to the trailer. I'm leaning towards bad breakers, or faulty power center. Any ideas?

      mudbug, you may have toasted the converter unless it has a fuse or reset button. Try connecting a good battery charger up and if everything works normally, then a new converter may be in your future.

      JustPat, make sure the negative battery cable is clean and tight where it attaches to the steel frame of the camper. A bad ground at this point will cause all sorts of problems with the 12 volt system.

      You should get at least 13 volts at the batteries if the converter is working properly. Hote this helps.

      Hi Randy. I have 2x6V batteries in series. Jayco trailer works on 120v, but not off the batteries. They are new batteries fully charged. Checked the fuses & breaker. I am getting 12V from the trailer when connected to 120V. And I see 12V from the batteries w/o 120V.

      Zachary, check the power in the 110 volt power panel in the camper. It's not uncommon for the main breaker, or one of the others, to go bad. Running on a small extension cord is never a good idea even though the voltage you may be using is minor.

      I have a 1985 wilderness by fleetwood, plugged into house with a extenion cord to connect house power to the cord from the outside of the camper. I only run a eletric fan that consumes up to 120 volts. Sunday night the whole camper lost power in ever outlet. I flipped all the breakers inside the house thinking maybe that was it, that did not work, checked the extenion cord that I used from the house and that was providing power. I am not sure what to try next.

      Follow up to 2004 Dutchmen Aero.

      Took you advice to check ground....it seemed to be ok. (Is there a way to post pics...to be sure I'm checking proper wire). I did remove and clean.

      After doing this, I checked the black wire leaving the battery. It was connected to two breakers before going to electrical box under trailer. The breakers were quite rusty and multimeter showed one didnt have power. So replaced with new breaker and the12 volt lights worked.

      At this time the battery had a charge.

      Was going to replace second breaker even though it seemed to be working, but was having trouble due to rust. A guy said since Im not planning on towing the trailer, to alter a black wire on breaker. Which I did and system seemed to be fine.

      A week or so later the 12 volts were dimmed, then day later 12 volt not working. Checked the battery and no charge. Charged battery overnight and everything works.

      Seems when plugged into power the battery is not being charged. Would this be the converter or could it be the altering of black wire between breakers?

      Thanks again.
