Electricity enters the home through a control panel and a main switch where one can shut off all the power in an emergency. These panels are usually located in the basement.

Control panels use either fuses or circuit breakers. Install the correct fuses for the panel. Never use a higher-numbered fuse or a metallic item, such as a penny. If fuses are used and there is a stoppage in power, look for the broken metal strip in the top of a blown fuse. Replace the fuse with a new one marked with the correct amperage.

Reset circuit breakers from “off” to “on.” Be sure to investigate why the fuse or circuit blew. Possible causes include frayed wires, overloaded outlets, or defective appliances.

Never overload a circuit with high-wattage appliances. Check the wattage on appliance labels. If there is frayed insulation or a broken wire, a dangerous short circuit may result and cause a fire. If power stoppages continue or if a frayed or broken wire is found, contact an electrician.
