Customers using generators should make sure their wiring system is disconnected from our system before operating the generator. When using a portable generator, make sure the main circuit breaker in your electric service panel box is in the Off position. If you have a fuse box instead of breakers, pull out the main block, remove the fuses and reinsert the empty block. This is necessary to prevent your generator's electricity from going back into our system, which could endanger the lives of line crews and your neighbors. Also, it's required by the National Electrical Code.
IMPORTANT: USE GENERATORS OUTSIDE ONLY

Never use a generator inside buildings, vehicles, basements, or any enclosed areas - the exhaust fumes contain poisonous carbon monoxide and can kill or cause serious injury.
