How to add key interlocks on Switchboards?

Key interlocks may be added to WL, VL & Sentron breakers, and Bolted Pressure Switches.

Note:

• Key interlocks are not available of VBS or HCP switches

• The key designation is the name of the key. This will usually be unique for each circuit or lineup. Consult with factory for more information on key schemes
