Installing and Removing Plug-in Units

Remove a Plug-in Unit with a 
Vertical Operating Handle 
from a Section 

To remove a unit, follow this procedure.

1. Make sure the disconnect handle is in the OFF/O position.

2. For non-arc resistant units, turn the door latches 1/4 turn; for units that 

are equipped with arc-resistant door latches, push in the latch and rotate 
1/4 turn.
