One of the most important accessories for a generator is a transfer switch. A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that the operator affects the transfer by throwing a switch, while others are automatic and switch when they sense one of the sources has lost or gained power.
Failure to maintain your transfer switch leaves you susceptible to unnecessary downtime.
Your standby generator won’t get called upon if your transfer switch hasn’t been properly maintained. Our transfer switch maintenance plan includes the following points of inspections to help ensure a reliable transfer of power to your generator. It is best practice to implement an ATS maintenance plan along with your generator maintenance.
AGS technicians are trained to service all makes and models of transfer switches. In addition, we have rental switches and can assist in purchasing new equipment if necessary.
