How Generator Transfer Switches Work
For a basic understanding of how generator transfer switches work, let’s imagine a scenario of a power outage. When the outage happens, your generator transfer switch will detect the loss of utility power. It then signals your generator to start operating.
Once the generator is ready, the transfer switch will shift the power from the utility to the generator. When regular power is restored, the process is reversed, with the switch transferring power back to the utility source and instructing the generator to stop.
Types of Generator Transfer Switches
Generally, there are two types of generator transfer switches: manual and automatic.
Manual Transfer Switches
Manual transfer switches are typically used for portable generators. These switches require your direct intervention when the power goes out. You must manually shift the power from the utility to the generator, and vice versa when the power is restored.
Automatic Transfer Switches
On the other hand, automatic transfer switches are used for permanent standby generator systems. They do not require manual operation. Upon detecting a power outage, they automatically switch power to the generator and shift it back when the utility power returns.
