How does a generator work?

The electrical generator

An electrical generator is really no more than a piece of equipment that creates electricity either by means of gasoline(unleaded or diesel) or by LP gas (liquified petroleum gas or propane). A second piece of equipment called a transfer switch sits between the generator and the electrical connection to you local power company.

A flip of a switch to get the generator running

The transfer switch sits and gauges the current flowing through the power company connection and your home or business. If and when the power is lost,(i.e. blackout, brownout, etc.)the transfer switch sends signals to the generator to start up because it will now be the source of electricity for your home or business.

After a short warm up period, usually 10-20 seconds, the transfer switch flips the switch so that power now flows from the generator to your home or business and blocks the connection to the power company.

The switch back to normal power.

At this point, the generator will run until it either runs out of fuel or until the power is restored. The transfer switch is constantly sensing for the current to be restored on the main power. Once that happens, the transfer switch flips the switch back to the original state, gauges that the electricity is flowing correctly into your home or business and then tells the generator to power down.
