Home Backup Generators

By Ray Hauser


The storm hit suddenly and violently without much warning. Forecasters didn't predict the heavy snow and wind unusual for October even this far north. Within hours, the heavy, wet snow began straining branches and power lines. Trees had yet to shed most of their leaves which captured the snow and multiplied the weight. Loud snaps and cracks could soon be heard reverberating throughout the vicinity as branches came crashing down taking out power lines, rooftops and anything else in their way.

By evening, power was out in the neighborhood and most surrounding areas. As the winter blast subsided, a strange, eerie darkness descended upon the storm ravaged area. Candles and flashlights cast fleeting shadows in homes up and down the icy street.

When the power went out in our house, a Generac Guardian standby generator came on within moments and supplied power to dedicated circuits energizing lights, the furnace, refrigerator/freezers along with a few nonessential items such as television sets and computers.

Half the homes in the neighborhood were without power for at least three days and almost a quarter of those homes had no electricity for over a week. Food spoiled, basements flooded and some people were actually forced to abandon their homes.

The National Oceanic and Atmospheric Administration (NOAA) estimates that there will be a 7% annual increase in utility outages over the coming years with costs reaching $1.5 billion per year. Emergency backup power can not only bring peace of mind, it can also save time and money.

Standby generators work on a pretty simple premise. An electric utility grid supplies power to people's homes. The utility grid gets its electricity from generating plants which in turn derive their energy from nuclear, hydro or fossil fuels.

A home, standby generating system is comprised of a generator and a transfer switch. The generator itself is powered by an internal combustion engine which runs on propane or natural gas. The generator is installed outside the home generally near the incoming power lines. The transfer switch is located alongside the circuit box inside the house.

The backup system constantly monitors utility power. If there is any loss or interruption of this service, the transfer switch disconnects the home electrical system from the utility grid and transfers it to the standby generator. The generator then starts up and supplies power to a set of dedicated home circuits. When utility power returns, the transfer switch reconnects utility power to the home and the generator shuts down returning to a quiescent standby mode.

The first step in selecting a home, standby generator is to determine how much power you might need, if there is a general utility outage. What devices do you want to operate including lights, furnace, refrigerator/freezer, televisions etc? Most devices are clearly labeled with their wattage ratings, so it's fairly easy to add them up to calculate your total power needs. After a determination is made on how much power is required, it is simply a matter of finding and installing the right size generator.
