Automatic switching from the control room is possible only if the breaker Loc/Rem switches are held on “Remote.” All the breakers and controllers are provided with means of operating from a local and remote position. The breakers that are left on Loc position (most likely intentionally) will not be restored. The means of communication from the plant control system to the switchgear is by Ethernet (see Chapter 17).

Breaker Loc/Rem switch operation:

 Loc (Local) means manual.

 Rem (Remote) means automatic from control room.
