It is your responsibility to protect your equipment from power outages and fluctuations. You should protect highly sensitive equipment by installing sensors designed to shut off the power supply if extreme power fluctuations occur.
Unprotected equipment should be unplugged, or the circuit breaker shut-off, until the power is restored. We suggest leaving one light on so you will know when power has been restored.
Once the power has been restored for about ten minutes, equipment should be brought back on-line in stages. Energizing one breaker or fuse (or large piece of equipment) at a time and ensure the equipment is functioning properly before moving to the next breaker or fuse provides additional protection for your equipment. In addition, waiting ten minutes before resetting the breakers or fuses will help eliminate problems that can occur if equipment is brought back on-line before SDG&E's system is stabilized.
If the doors are kept closed on refrigeration equipment, the contents can be maintained for several hours. Dry ice can be used to protect the contents during extremely long outages. Use gloves when handling dry ice, and use caution not to place it directly on the contents.
