TFW Electric in Atlanta GA recently completed an electrical project consisting of installing a 400 amp service and transfer switch for a whole house generator.
A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and switch when they sense one of the sources has lost or gained power.
Automatic home generators keep the power going by providing dependable protection during unexpected power outages. In the event of a utility power outage, the transfer switch - working in tandem with the generator - automatically starts the generator to restore power to the home, whether you're home or away.
