Operating Positions
Withdrawable units have four operating positions: Connected, Test,
Disconnected and Withdrawn. 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.
Three or four pole 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, located on the left side of
the column. See the following descriptions for additional information about
the features of each position.
