The mid trip circuit breaker will trigger an alarm only when it is
electrically tripped ( for example : overload ), not when it is manually put
in the OFF position.
Note : Circuit breakers with a capacity of more than 80 A must
be located adjacent to circuit breakers having a capacity
of less than 65 A.
Internal connecting features of the NT6C14GA/GM and NT6C14GP
control and distribution panels
The inside of the NT6C14GA/GB/GM and NT6C14GE/GF/GP control
and distribution panels contain the following terminal blocks and
connectors.
Terminal blocks
There is one 4-position screw-type terminal block (TB1) on the back of the
front door of the control and distribution panel to connect small loads to
QFF type fuses F1 to F4.
There are three 8-position screw type terminal blocks (TB1, TB2 and TB3)
on the controller card itself to interface with alarm signals, sensing signals
from busbars, FA IN signals from distribution fuses and circuit breakers,
and the battery disconnect panel, if provided.
