Learn about BHG's Editorial Process Updated on March 8, 2024 Close Before you start every electrical project, make sure you know how to turn off the power in your home. We'll show you how to make sure your home circuits have been switched off so you can safely proceed with electrical work. Our guide will also help you know what to do when lights or receptacles suddenly go dead, which could indicate that a circuit has overloaded. To turn off the power in your home, begin by locating the electrical service panel, then follow our step-by-step instructions below. If you have an older home, you might have a fuse box instead of a circuit breaker, so if this is the case, head to our tutorial for how to turn off the power at the fuse box. How to Install an Electrical Subpanel Jacob Fox Locate Your Home's Service Panel A residential main service panel contains either circuit breakers or fuses and is usually located in a utility area. It should be easily accessible but away from the main traffic flow in the house. The panel may be in the garage or basement. In warm climates, it may be on the outside of the house. In an apartment or condo, it may be recessed into the wall in a closet or laundry area. The service panel is likely a gray metal box or door unless it's been painted. When locating your home's service panel, you might find more than one, especially in an older home. Subpanels are sometimes added to older systems to expand the number of circuits. Turn off the power on these like you would a fuse or breaker in the main service panel. You might need to get to the service panel in the dark or in a hurry during an emergency. Make sure all adults in your home know where to find the breaker box and how to turn off the power. Keep the path to the panel clear, and don't lean anything against it. How to Install a 240-Volt Receptacle Dave Toht Examine the Breaker Box and Turn the Power Off Once you've located the breaker box in your home, open the door to get to the fuses or breakers inside. Call a professional electrician to check if the service panel appears damaged or if loose wires are visible. After opening the service panel door, you'll see rows of individual circuit breakers, which look like toggle switches, and a main breaker on top. A list indicates which parts of the house each breaker controls. The list should identify which breaker controls the receptacle or fixture you want to de-energize. These are individual breakers. To shut one off, flip the lever to the "off" position. Test the device to make sure the power is off before working on it. To turn off the power to the entire house, flip off the main breaker, usually a double-width switch located at the top of the service panel. You might need a flashlight handy when you turn off the power to your entire home. How to Turn Off Power at the Fuse Box in Older Homes Dave Toht How to Reactivate Tripped Breakers Breakers vary in the way they shut off when they sense an overload. One toggle type has a red button that pops up when the breaker has tripped. Reactivate it by turning the switch back on. Some toggles turn partway off when they blow. To restore power in a breaker, flip the switch all the way off, then on. The button on a push-button breaker pops out when the breaker shuts off; push the button in to restore power.
