ST Type Transfer Switch with Back up Circuits

ST type panels provide transfer capability to a select number of critical circuits, as opposed to the entire house. For the chosen critical circuits, the conductors in the main house panel are removed from the breaker and connected with wire nuts to the pre-wired conductors on the transfer switch.

Overview

“ST” type transfer switches, denoted in the catalog number starting with “ST”, are compatible with the Nexus controller. The Nexus controller senses power outages and initiates the transfer of power to the generator via the automatic transfer switch.
