Choosing a Generator
Any owner, renter, or lessee who possesses and operates an electric generator, when the generator is connected to a commercial, industrial, or residential structure’s electrical system that’s connected to the service of a public utility or utility district, shall notify the utility of the location of the generator.
Using a small standby generator for electricity during an outage can keep your home and business running smoothly. In a power failure, you would plug your generator into the panel with a special power cord and then switch the circuits from utility to power to your generator.
- Types. The two main types of residential generators are portable and permanent standby.
- Sizes. Standby generator sizes range from an output of 1 kw to over 100 kw. If you plan to run a few lights and minimal appliances, you can use a smaller model, but if you intend to run all your lights and several major appliances, you will need a permanent standby model.
- Fuel. Engines usually run on gas or diesel, but models are also available for propane or natural gas.
- Selecting a Generator
- Power for the basics. Smaller, portable models will power basic necessities and cost $1,000 or less.
- Evaluate your needs. Match the size of your generator to your electrical needs. Operate it at no more than 75% of its capacity.
- Calculating size. To calculate your generator size, total the wattage of the appliances and other items you want to simultaneously power and then double that number. Most homeowners will need a 5-kilowatt portable generator to power a heating system and a few other appliances.
- Manual transfer switch. Consider a manual transfer switch, which costs around $500 and should be installed by a licensed electrician.
- Safety Tips
- Store your generator outside in a dry location to avoid carbon monoxide poisoning.
- Never plug a generator into any electric outlet in your home or business. It can be deadly.
- Follow all instructions on properly “grounding” the generator.
- Turn off the generator for at least five minutes when refueling to avoid starting a fire.
- Keep extension cords out of the way so they don’t present a tripping hazard.
