As noted, the power output is determined by the load or the amount of power required to run the appliances and devices you need to keep the electricity on during a power outage.įor example, a 5kW generator can typically power a fridge, fan, lights, and a few other small appliances. The power output of a generator is measured in watts (W) or kilowatts (kW). The amount of power needed depends on what that power will be used for. Generators are available in a range of power capacities from five kW to 50 kW for residential use and 50kW to over three megawatts for commercial and industrial applications. Residential generators are typically powered by natural gas or propane, as these are the most commonly available fuel sources for homeowners. Most industrial generators run on diesel fuel, as it’s the most efficient and cost-effective option. Generators use a variety of fuel sources (including gas, diesel, propane, and natural gas) to power the motor. The current generated can then be used to power appliances, lights, electronics, and other essentials during a power outage. This field interacts with the conductor coil, which agitates the electrons and causes them to flow freely, creating an electrical current. The motor spins the coil inside a permanent magnet, which creates the electromagnetic field. The generator features a copper conductor coil with a metal core connected to a motor. There must be a closed circuit for electricity to flow, meaning the electrons can flow freely from one end of the conductor to the other without any gaps.Ī generator creates a closed circuit by using a magnet to create an electromagnetic field. Electricity is the flow of electrons through a conductor (e.g., a wire). To understand how a generator works, you should first understand how electricity works. In that case, a generator can keep the lights on and power essential appliances until repairs can be made.

For example, suppose inclement weather knocks out power lines, and the electrical grid goes down. Generators, also called on-demand or standby generators, provide backup power when there’s an interruption in the main power supply.
