How To Change A Fuse In Your House: A Step-by-step Guide

As a homeowner, it's essential to know how to change a fuse. Fuses protect your electrical system from overload, and they can burn out due to a surge in electricity or a faulty device. If you're wondering how to change a fuse in your house, keep reading. In this article, we'll provide a step-by-step guide to help you replace a blown fuse safely.

Step 1: Turn Off the Power

Before you attempt to replace a fuse, you must switch off the power. Go to your electrical panel and turn off the main switch. This switch will shut down the power to your entire house. If you're not sure where your electrical panel is located, check your basement or utility room.

Step 2: Locate the Blown Fuse

Once you've turned off the power, locate the blown fuse. Your electrical panel will have a series of fuses or circuit breakers. A blown fuse will have a broken filament or a blackened glass window. You can also use a multimeter to test the fuse's continuity.

Step 3: Remove the Blown Fuse

To remove the blown fuse, use a fuse puller or a pair of needle-nose pliers. Hold the fuse by the ends and gently wiggle it out of the socket. Be careful not to touch the metal parts of the fuse, as they may still be hot.

Step 4: Replace the Fuse

Once you've removed the blown fuse, replace it with a new one of the same amperage rating. You can find the amperage rating on the fuse itself or on the panel's door. Make sure to push the new fuse firmly into the socket.
