About this detail

Wiring configuration for a generator transfer device (GTD) interfacing with an emergency power panel and a normal power source. Connections run from the generator through a transfer switch to the emergency panel, alongside normal power routing through a wall switch or occupancy sensor. Specific wire color coding is designated for the GTD unit, including brown, red, and blue leads, a voltage sensing lead with 120V black or 277V orange options, and neutral connections linked back to respective normal and emergency panel neutral buses. The AC driver fixture connects via black and white leads while maintaining isolated neutral pathways.
