Standards and Certifications
Class CTL
National Electrical Code
Paragraph 384.15 requires
branch circuit panelboards
to be provided with physical
means to prevent the
installation of more
overcurrent devices than
that number of which the
enclosure was designed,
rated and approved. Class
CTL Duplex, Quadplex and
twin breakers (identified
by a catalog number prefix
BD, BQ, BQC and CHT)
are equipped with a
UL listed rejection tab
over the line terminal.
All OEM interiors have
appropriately notched stabs
to accept these rejection
tab Class CTL breakers.
Duplex, Quadplex and twin
breakers manufactured
without the rejection tab
(identified by a catalog
number prefix BR, BRD
and CHT) are available
for replacement purposes
in older interiors.
Federal Specifications

Lighting and
Appliance Panelboards
Lighting and appliance
branch circuit panelboards are
defined in NEC (Article 384)
as “One having more than
10 percent of its overcurrent
devices rated 30 A or less for
which neutral connections
are provided.” Article 384
also limits the number of
overcurrent devices (branch
circuit poles) to a maximum
of 42 in any one cabinet.
When the 42 poles are
exceeded, two or more
separate panels are required.
