Test fuse with multimeter

Glass fuses have a low breaking capacity. It's easy to see when they're blown: the glass will be discolored and the filament broken. Replace yours today!

The fuse contains a metal filament that burns when the fuse blows during a current overload. It is necessary to test a fuse to confirm it is in good condition and can protect an electric circuit or device from catching fire.

More results A simple fuse test is one of the easiest ways to troubleshoot equipment. You can do it at home, and all it requires is a multimeter—sometimes not even that. Essentially a safety device, fuses protect against overcurrent caused by a fault, overloaded circuit, damaged wiring, loose screws, etc. The wire within the fuse will melt and break the circuit, turning off power to the device. The good news is testing for a bad fuse is pretty straightforward. Sometimes you can even tell if a fuse is blown just by holding it up to the light. If the wire is broken or a burn mark appears on the metal, you should go ahead and replace it. This alternative way to test your fuse with a multimeter checks whether there is a path for electricity to flow. Follow steps from above and then substitute with these:.

Electrical circuits are peculiar in the sense that its the smallest components within them that play the biggest roles. The fuse is one of these small components, serving as a self-sacrifice that prevents unexpected power surges from rendering the entire circuit useless. Is a device within your home or car not receiving power? Do you suspect that the problem is from the fuse box? Fuses are simple components designed to protect electrical circuits from power surges or overloads. The current a fuse may hold is known as its ampere rating, which goes from as low as 10A up to A. The most common type of fuse found in various electrical devices is the cartridge fuse, which is cylindrically shaped, usually transparent, and comes with two metal tabs at both ends.

They have metal contact or terminal points on either end and consist primarily of a tube that contains the wire. Note: Before conducting any tests on live circuits, be sure to wear personal protective equipment e. Cartridge fuses are commonly used to protect electrical appliances like refrigerators, motors, and air conditioners. A fuse is an electrical component designed to protect power lines, cables, and equipment from excessive temperature and power surges by safely opening a circuit when an abnormally high current flows through it. What are you looking for? Fuses are really just wires that are designed not to last, but their purpose is to prevent damage to more valuable electrical equipment or prevent fires especially in homes caused by power surges.
