• If a fuse blows, turn off all appliances and lights that are on the circuit before changing the fuse.
• Use a flashlight. Don't try to replace a fuse in the dark.
• Replace a fuse with another that has an identical rating.

• Use only three-pronged extension cords outdoors.
• Keep cords away from sources of heat and water.
• Cords and plugs that show signs of wear or damage need to be replaced. Stop using them immediately.

• Always use the right tool for the job. Shortcuts and using the wrong tool is likely to result in an accident.
• Never use a tool that has frayed cables or exposed electrical wires.
• Comply with manufacturer’s instructions.
• Ensure that all guards are in place before using your power tools.

Listen to your breaker - A breaker that trips immediately after it's reset is telling you that there's an electrical problem. Sometimes the breaker itself is to blame, and in some cases there may just be too large an electrical load operating on that circuit. But it's more likely that the breaker is tripping because there's a severe electrical problem. Keep pressing that breaker, and you may cause a fire.
