Transfer switches are two-way manual or automatic switches that are used to switch or transfer an essential load from the main power source to a backup power source.
In the Electrical Engineer, the software displays a transfer switch as a normal bus with two incomers. You drag each incomer separately to its parent power source. The software shows the two paths separately, with the items downstream of the transfer switch repeated on each path. The software can display transfer switches and their electrical paths in single line diagrams.
