Duplex Circuit Breaker
Tandem/duplex breakers are convenient for adding circuits to a
full loadcenter and are sometimes used to reduce the physical
size of the loadcenter.
BD Breaker
Class CTL (Circuit Limiting).
They will only fit onto loadcen-
ter bus stabs that are notched
to accommodate the rejection
clip built into the bus bar
contact on the breaker. This
is a code requirement that
limits the number of breakers
that can be installed into a
loadcenter.
BR Tandem
Identical to BD tandem break-
ers, except they do not have
a rejection clip on the bus bar
contact. Not Class CTL and
are intended for replacement
purposes on loadcenters
made prior to 1968.
Circuit Limiting:
Notched Bus Stab
(BD Only)
Non- Circuit Limiting:
Unnotched Bus Stab
(BR Only)
