    Manual Transfer Switches

    How does a manual transfer switch work?

    When transferring electricity between two sources, it can be done either automatically or manually. Manual transfer switches must be thrown by an operator. The operator can also choose which circuits they’d like to power either before or after the switch is thrown. They are installed next to a building’s main electrical panel for easy access during a power outage.

    Commonly used across residential, and commercial applications, though also used in industrial and agricultural sectors, manual transfer switches come in a variety of models and types including: 100 amp manual transfer switches, 200 amp manual transfer switches, and 3 phase manual transfer switches.

    From your utility, to your generator, and back again.

    Manual transfer switches are essential when using a backup generator. Manual generator transfer switches are connected to your load center and designed to deliver a constant, reliable flow of electricity during a blackout when thrown by the operator. They can be installed both indoors and outdoors, though any outdoor manual transfer switch must be properly protected.

    Manual transfer switches are popular in homes, so if you’re working with a residential backup generator and you’re looking for a generator transfer switch, manual would be a popular way to go.
