Panelboard General Specifications
Class CTL Panelboards
Class CTL panelboards incorporate physical features which, in
conjunction with the physical size, configuration, or other means
provided in Class CTL circuit breakers, are designed to prevent the
installation of more overcurrent protective poles than that number
for which the device is designed and rated.

Service Entrance Equipment
When a panelboard is used as service entrance equipment, it must
be supplied with the appropriate CSA certification and labelling.
Please consult CSA, CEC and local inspection authorities for
specification and installation guidelines.
Panelboards must be identified as “Service Entrance” at the time
of order entry.
Also panels must include a connector for bonding and grounding
neutral conductor.
Integrated Equipment Short Circuit Rating (Series Ratings)

application of series connected circuit breakers in combination
that allows some breakers to have lower individual interrupting
ratings than the available fault current. This is permitted as long as
the series combination has been tested and certified by CSA.
“Series Rated” must be identified at the time of order entry.
