Entire House Generators – a review of what it really means, and how much power you receive
Some standby generator packages are identified as providing “entire home power” meaning they’re able to power everything at your residence. The packages more often than not have an automatic transfer switch with power management features.
Alone, “entire home power” ensures that the whole property is furnished with power, however not all generators are capable of producing enough power to support all appliances and lights simultaneously.
Home Power Use
The typical new home in the USA carries a 200-amp service panel with a lot of circuit breakers. In the event the amperage of all breakers within the panel are added up, they may total around 800 amperes, far more over exactly what the panel or main breaker are prepared for. If all of the home’s appliances and lights were switched on, the complete would still not exceed 200 amperes and the main breaker wouldn’t trip.
Safety and convenience dictate the size of the primary service panel and the volume of circuits it supplies. The size of the primary breaker is not a good indicator of the volume of power the entire house uses.
Power Management
Managing power takes two forms. Homeowners do their part by switching off nonessential appliances and lights while operating on standby power. What produces a nonessential appliance is determined by your situation along with the capability of the entire house generator. Power management devices for example load-shedding controllers or digital power management systems prevent backup generator overloads by limiting the volume of high-demand appliances that operate simultaneously.
Automatic Transfer Switches
The automated transfer switch is an essential part in the entire home generator system. Their installation configures them since the gatekeeper for electricity for the entire home. During normal operation, they send power from the electric utility to the main service panel. When utility power fails, they disconnect the utility lines from the home and route power from the entire home generator to the main panel.
To satisfy electrical codes, the automatic transfer switch current rating within a entire home power configuration must equal or exceed the primary circuit breaker current rating. A 200-amp main circuit breaker needs a 200-amp or greater automatic transfer switch. By using a smaller switch for entire home power may cause a fire or permanently damage the switch.
Entire House Generators
Generators are rated in watts (W) or kilowatts (kW), a measure of the work electricity is capable of doing. Air-cooled generators for entire home power begin with ratings of around 8,000 watts (8 kW) and top out at approximately 20,000 watts (20 kW). Liquid-cooled generators for residential applications offer 20 kilowatts to 65 kilowatts of electricity.
By comparison, 100 amp main circuit breaker are prepared for about 24,000 watts of power along with a 200 amp panel about 48,000 watts of power. Take into account that your home never uses the volume of power the primary breaker is designed for.
Picking a Home Standby Generator
For most applications, you shouldn’t have or economical to install a whole house generator able to offering the equivalent power the primary circuit breaker is designed for. By utilizing power management devices and judicious homeowner power use, smaller generators will supply the entire house with electricity.
Perform a power audit to determine all the power used at the time. Figure out what high voltage appliances are necessary and which are not. Finally, decide on a backup generator package which will match the power needs of the entire home and employ power management devices to regulate the energy supplied to high profile appliances for efficient entire home energy that suits you.
