Operating Positions

Withdrawable units have four operating positions: Connected, Test,
Disconnected

, and Released. Detents are present to confirm that the unit is in

one of the four positions. An interlock helps prevent the unit from being inserted
or removed while the branch circuit device is in the ON/I position. Stabs are
provided to make the line and load connections. A first make, last break PE
contact is also provided. Control and network connections plug into an isolated
vertical wireway on the left side of the column. See the following descriptions for
additional information about the features of each position.
