the circuit breaker to "off" or removing a screw-in fuse. Remember that the electrical power is still live to the service panel from the power utility lines (either below or above ground), so even if you switch off the main power, the power is still live to the service.

Be certain that the circuit is off by first turning on a light that's plugged into that circuit. If it goes out when the circuit is switched off, proceed with your next steps.

Tell others that you are disconnecting a circuit. This is important when working at some distance from the service panel. Tape a note to the service panel warning others that you are working on the service.

Never work on the service panel or wiring when there are wet spots, moist conditions or standing water. Dry the area as much as possible. Open windows and doors to aid in drying damp basements. If there is moisture on the floor, construct a platform of dry boards over the wet areas.

At right is a typical subpanel installed above the main circuit breaker panel. Below the main panel is a Gen/Tran unit - used for connecting a portable generator to the main panel in the event of a power outage.
