Before Using a Generator
During power interruptions, properly sized and installed emergency generators can safely power electrical equipment such as portable heating units, computers, water pumps, milking machines, home freezers, refrigerators and lighting. If you use an emergency generator, it is essential that you take precautions for your safety and for the safety of those working to restore power.
- Select a proper generator by evaluating what appliances you really need to power in an emergency.
- Read, understand and follow the manufacturer’s instructions.
- Be sure that you fully understand the proper installation and operating procedures for your unit. If possible, have your generator installed by a qualified electrician.
- Before installing a generator, be sure to disconnect properly from your utility electrical service.
