Modern caravans are designed to provide electricity, making these houses on wheels very comfortable and convenient for travelling. However, with all the circuitry and wiring, breakdowns can be a common occurrence, whereas regular maintenance is important. Hence it is important to understand the basics of the electrical system in your caravan.

Like the conventional electrical system, the fuse in a caravan is a small metal wire that gets heated and blows up when excessive current flows through the circuit, helping save the device. If the fuse blows up, you will need to replace it.

The fuses in a caravan power various devices. These may include lights, stereos, and other electric appliances. The circuit breakers in the caravan protect the supply cable; however, as they are intended to cope with the electricity load, they may not respond quickly and safeguard the appliance. It is why the connected appliance must also have an adequately rated fuse.

Regular fuses are quite cheap and come in various types, including relay fuses, glass barrels, or automotive fuses. There is a filament inside the fuse that burns up and stops the current flow

for the automotive and glass barrel fuses.

Relay fuses are automatic fuses that trip when overheated due to excessive current and stop the current flow. Once the fuse cools down, it turns back on. The fuse may continue to repeat the pattern if not fixed or until it burns out.

So, if the lights in your caravan go out, or any other appliance, like the TV, turns off or stops working, the reason may be a blown a fuse. The good news is that fuses are easily available from hardware stores and are easy to replace.

All you need to do is locate the fuse box panel, identify and test the fuse to make sure it is not working, then pull it out and put in a new one. A handy tip is to carry a spare fuse, a pair of pliers, a test light, and fuse pullers when travelling. You never know when you may need them. Here is a step-by-step process for replacing a caravan fuse.

  • Firstly you need to find the fuse box in the caravan’s electoral compartment and open it. The electrical compartment may be in a cabinet or closet, behind a panel under a set, or on the wall. You can refer to the caravan manual if you cannot locate it.
  • Check if there is any tripped breaker. If yes, flip it back on to see if only the breaker had tripped.
  • Check the fuse labels to locate the one for the appliance that has stopped working.
  • Once you have located the correct fuse, check it with a test light to see if the light on the tester handle goes on when touching the fuse. If the light is turned on for both the fuse sides, it means the fuse is fine, and the problem is somewhere else. However, if the light does not turn on, it means the fuse must be replaced.
  • If you do not have a replacement fuse, purchase one with the same ampere rating and voltage. You will find it written on the fuse. These fuses are quite cheap, and it is better to keep spare fuses when you are on the go so that you can change the fuse without any issues.
  • To replace the fuse, turn off and unplug the electrical appliance for which you are replacing the fuse in the first place.
  • Now pull out the blown fuse from its place via pliers or fuse pullers and plug in the new fuse in the fuse block space.
  • Test the new fuse and the electrical appliance that corresponds with it. Make sure to check the right and left sides of the fuse with a test light and see that the light in the handles comes on.
  • Now plug your appliance back in and turn it on to see if it works. If yes, it means that you have successfully replaced the fuse. If not, you may need to see for any other problem. Sometimes, there may be a problem with the appliance. For instance, if the fuse was for a light bulb and the bulb was not working, it may mean it had blown, and you need a new bulb.
