Basic Precautions

Changing fuses or doing electrical work around the house?

• Always disconnect the power by moving the main switch or breaker to the "off" position.
• Never change a fuse in a dark room or while standing on a wet floor.
• Before changing the fuse, unplug appliances on the overloaded circuit and turn off the main switch.
• Install the proper size fuse. All lighting and general use circuits are fused at 15 amps.
• Never replace a fuse with a penny or other metal object.
• There are two types of fuses: "P" or "D."
  • P fuses are recommended for general circuits, especially those to appliances that heat but aren't motorized (water heaters, baseboard heaters and stoves).
  • D fuses should only be used for large motorized appliances —dryers, furnaces, refrigerators, freezers and window air conditioners – because they can handle power surges when the appliance motor activates.

Do you know the warning signs?

• Circuit breakers that trip repeatedly or fuses that blow for no apparent reason.
• Rust in the fuse box, overheating, discoloration in the fuse box or flickering lights.
• Cracked or discoloured extension cords
• Warm cord or plug
