  • Q: What should customers do with appliances and electronic equipment?

    If power to your home or business is interrupted, the best thing to do is leave only a light or two on -- so you know when power is restored. Turn any air-conditioning appliances off, if possible. Keep any refrigerators or freezers closed as much as possible until power returns.

    Customers are asked to turn off electrical equipment during a blackout so that when power is restored, the system can return to normal as quickly as possible. If large equipment is not switched off, the surge of power trying to restart all of this equipment will trip a circuit breaker again. This could delay by hours the orderly restoration of power to an area.
