Be sure to check why the fuse or circuit blew. Possible causes are 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.
Circuit testers are available to inspect circuits.
If power stoppages continue, or if there is a frayed or broken wire, contact an electrician. Install a lock out switch. This can turn off all power from one area. This is important if there is an emergency or when working on the electrical system. Do not have a switch turned on while you are working on the electrical system.
