78 System Manual, 11/2013, 110 0110 - 02 DS 03
Busbar connections
Busbars or cables can be connected direct to the front of busbar extensions or to bolts for
connections on the back. If straight busbar extensions are used, terminal covers or phase
barriers are recommended.
Mounting plate
Plug-in bases with flat terminals on the front or rear are available for direct connection of
cables or busbars. The plug-in base is attached direct to the mounting plate supplied by the
customer.
The appropriate safety clearances must be observed. Terminal covers or phase barriers are
available for the front connecting bars. Molded case circuit breakers cannot be removed from
the plug-in base in the "ON" position. The molded case circuit breaker will go to the "tripped"
position if attempts are made to remove it while in the "ON" position.
