We can check the fuse visually to see if it's broken or we can do an electrical test on the fuse using a multimeter to see if it's good or blown. The Ferrule-type cartridge fuse is generally used for the main feeder and range protection. Never replace a blown or suspect fuse with one of a higher rating. If the fuse turns out to be good, you can use a circuit tester to trace the wiring path and find out what's gone wrong. Visual Test of a Fuse. Always replace a fuse with the same rating as (or a lower rating than) the old one. Perform a quick test of the meter to ensure it’s functioning properly by touching the leads together until you hear a … If the circuit doesn’t blow, turn the lights back on and plug in appliances one by one to check for the overload or short circuit. To double-check that diagnosis, try disconnecting some of the electrical loads on that circuit, reset the breaker and wait a few minutes. If the translucent area is blackened, it is. If you want to use the meter as an ammeter, keep reading! It is easier to test fuses than it is to test other electrical equipment. 2. Many types of fuses allow for visual confirmation that the fuse is still functional. This will measure the resistance of the fuse link, if intact. When this happens, no current can flow, and the circuit is disconnected from the power supply. Please help us continue to provide you with our trusted how-to guides and videos for free by whitelisting wikiHow on your ad blocker. Step 4: Reinstall the fuse and turn the main switch back on. If too much power runs through the fuse, it will "burn out," quite literally, and open the circuit, preventing the current from flowing through the circuit. Attach the clip for the test light to any bare metal, and use the probe of the test light to touch each end of a fuse. There are 2 tests we can use to check to see a fuse is good or blown.
