Testing a fuse with a multimeter: Our advice

Above all, if you are moving into an old house or if you want to acquire an old property, it is essential to test a fuse with a multimeter. Indeed, these dwellings may not have modern circuit breakers. To avoid any inconvenience in the medium or long term, the ideal is to test the fuses present. These are important because they preserve your installation during an overload load or a short circuit. For this reason, our experts provide you with very valuable advice.

Testing a fuse with a multimeter: The steps

If you want to test a fuse, start by bringing a multimeter. Then follow these instructions:

  • First, connect the black lead of the multimeter to “Com”;
  • Connect the red wire to “V”;
  • Set the multimeter to ohmmeter mode. Adjust the position to Ohm x 200 or Ohm x 2000;
  • First, test the device by crossing the ends of the cables. The display should show 0;
  • Then test your fuse. Place the tips on the ends of the fuse. 
  • If the screen displays 0, everything is fine, your fuse is working;
  • If it displays I, your fuse is blown.
  • If the screen displays OL for Over Limit, the fuse is considered out of order.

If in doubt, it is best to call an electrician. They will be able to test your installation and if necessary bring it up to current standards.

Upgrading your home's internal wiring may just be the renovation you and your home deserve. Here's how to know if your home needs an updated electrical wiring system and the many benefits one can offer. How the electrical system works Before you can assess whether an upgrade is needed, it is important to first understand the basic wiring operations in your home. Basically, your home's electrical system  is like the body's circulatory system. The electrical panel acts as the heart of the body, pumping energy through circuits (like veins) to all appliances and sockets in the house. An old electrical panel or inefficient circuitry means your appliances are not receiving a large blood flow of electricity. Hence, they will not work at their best.
