Why do appliances cause tripped breakers in your RV? Let us explain…. Believe it or not, this is such a common question. Some people have described an RV electrical system with such complexity that I felt I needed a NASA engineer to help me set up my camper for the weekend.
I panel spent a portion of my teenage years working in car and truck shops learning the ins and outs of automobile electrical systems. Your camper actually has 3 electrical systems. The 12 Volt DC Direct Current automotive system controls the lighting on the outside of your camper that deals with driving or towing it around on the roads.
This system originates with the tow vehicle for trailers, or the chassis on a class A or C units. It is charged by the alternator while the engine is running and provides the needed energy to power the headlights, marker lights, brake lights and signalling lights.
With a towed camper, this system is supplied to the camper via the cable connected at the hitch. Smaller units have a 4 wire connection and larger capacity vehicles will have a 6 or 7 wire connection.
The 4 electrical cable is usually found on smaller towing vehicles and is used for lighting only. The 6 or 7 check this out cable is found on larger vehicles and includes wires that control the brakes on a trailer.
How Does My RV Electrical System Work?
Some trailers, usually under 2, lbs, do not need brakes, where as the larger tow behind trailers need to have their own brakes to assist in bringing the entire truck and trailer set up to a safe stop. This circuiting is intended for the roadway lighting and, where applicable, the brakes only and is not intended to supply power to the 12 Volt DC interesting craigslist brevard fl so? system. A safety electrical that causes the trailer brakes to apply in the event that the trailer separates from the towing vehicle.
This circuit can easily be overloaded if you tried to power anything additional from it. Overloading it would most likely blow a fuse in the towing vehicle or the chassis fuse box in a class A or C unit. The 12 Volt DC camper electrical system originates with the battery s installed on the https://telegram-web.online/jehovahs-witness-dating-site.php. The system is broken up into circuits that are fed hookup the fuse block in the camper.
If you do not have experience with 12 volt DC circuits, do not add any electrical devices to the system without checking with a qualified person.
If a fuse blows on a 12 volt circuit, do not replace it until you have found the problem. NEVER put the next size up fuse in. Using the incorrect fuse size hookup create a fire hazard. For those that like to Boondock or camp at locations without electrical hookups, you can use the 12 volt system to operate most creature comforts.
However, only for as long as the batteries are able to last. Having a small generator can maintain the batteries, if you are allowed to use them. Some camping areas without hookups limit the time you can use a generator, mostly to daylight hours.
The last source of power in your camper is the volt AC Alternating Current system. This is just like the system in your house. It covers all of the outlets, the TV, the microwave, and the AC. It also covers half of the hot water heater the other half runs off of propane. For those with washers and dryers, they are covered by the volt system.
The power in the camper is supplied by either a 20 amp or 30 amp cord that you plug in while setting up your camper at the site. Again, it is no different than your house electricity, other than being limited to the total amount of power that is available to you. The power in your camper is protected by a small electrical distribution unit. The unit has breakers for the AC power and fuses like panel find in a car for your DC power. There are multiple AC circuits to protect the wiring click here the camper.
However, all of the camper circuits combined are limited by the breaker on the pedestal you plug into.
Your camper should have a separate circuit for the air conditioner, one for the hot water and another hookup usually covers all of the outlets including the microwave. This is why when you nuke your breakfast burrito while brewing your coffee, it tends to trip the breaker in the camper. If this happens, let the breaker rest for a few minutes before turning it back on. A breaker has a thin piece of metal inside that heats up as the load increases.
Understanding an RV Electrical System – How Does It Work?
This is what causes it to trip. You want to panel this cool off before resetting it, otherwise it may trip shortly after turning it back on. Read more can thank me later. I have heard people say that it is dangerous to use a coffee maker or any other type of appliance in a camper. We regularly use a coffee maker, an Instant Pot, a slow cooker, a toaster, an ice maker and my beautiful bride uses her hair dryer and flat iron.

This is all acceptable as long as you stagger the use. We see more only use the appliances while we are at the camper. So if the breaker that covers your counter top outlets has a 15 amp trip rating the number on the breaker handleyou should never put more than 12 amps of load on it at once. This also goes for the breaker at the pedestal.
If it is 30 amps, you should never apply more than 24 amps of load on it. The bigger hazard with Hookup electrical wiring is that it is always vibrating as you bounce down the road. This can lead to loose connections. A loose connection in an electrical system can lead to excessive heat at the connection. This may result in a fire. It is not a bad idea to check, or have a qualified electrician check, panel of the outlets and electrical connections every once in a while. Make sure you know what you are doing before you begin doing any maintenance to your electrical system yourself.
A similar problem with RV wiring is melting the shore line. This is usually associated with a really long shore line or using it with an extension cord. Longer cords add resistance to a circuit and can cause overloading. Make sure if you use extension cords, you get a heavy gauge extension cord. The larger the actual copper conductor, the less the resistance. I recommend at using at least a 12 gauge cord for any of your camper needs. Do not use 16 gauge cords. The lower the gauge number, the larger the conductor.
The Basics of an RV’s Electrical System
There is a reason the 16 gauge cords are less expensive. DO NOT use an extension cord on a 30 amp shore line without consulting a qualified person to ensure it is safe to do so. Some RVs have on-board generators that can supply power to the AC hookup outlets and devices. Generators are also protected by circuit breakers on the unit itself. Know where these breakers are in case your air conditioned breakfast adventure overloads the circuit.
When using a portable generator for power, make sure you set it up away from open doors and windows. We have packed a lot of technical information in this post, but tried to keep it as understandable as possible. The electrical system in your RV is quite simple and very similar to your home, with the 12 volt electrical added in. It is worth your safety to pay someone to do this.
So sit back, turn on the AC and enjoy! Typically, no. The circuit breakers should last the lifetime of the camper. Breakers can be damaged by exposure to water or frequent condensation.
They electrical also be damaged by being forced to trip too panel times. The breakers used in campers are Thermal Magnetic Circuit Breakers and trip for one of two reasons; high load or dead short. The first way most popular dating app in india they trip is by having too much plugged in and operating at the same time high load.
For example, a microwave and a toaster operating at the same time on one circuit. The high load heats up a little metal filament in the breaker. As it heats up, it contracts and releases a lock mechanism that then shuts off the breaker trips it. If this occurs many, many times it can alter the physical properties of the filament and cause it to trip under small amounts of load nuisance tripping. A breaker that trips under normal conditions should be replaced.
The site top face dating way this type of breaker trips is when the wire connected to it shorts or connects directly to another power wire or ground.
It can be from damaged wiring, a bad appliance or someone sticking a fork into the wall hookup. When electricity is shorted, it produces a very fast panel very large load, known to electricians as a High Inrush Current like a power surge. The speed and force of the electricity creates a magnetic field around the wire. Inside the breaker is a second trip mechanism with a magnet. The magnetic field created by the inrush current offsets the pull electrical the magnet holding the trip mechanism and the mechanism opens the circuit trips the breaker.
If repeatedly tripped, this can cause that mechanism to weaken and prevent the circuit breaker from staying on. Occasionally, one large surge can damage the mechanism and require replacement of the breaker. If a breaker is not holding properly or nuisance tripping, not only should it be replaced, but the circuit itself should be inspected to ensure there are no other problems that could be causing it.
If you are not familiar with electricity, hire a qualified electrician to investigate the problem. Where are all the different circiut breakers and fuses located?
