Short Circuit Current Ratings (SCCR)

SCCR are used to select end-use equipment for
specific available fault current applications. This
maximum current rating applies only to end-use
equipment such as switchboards, panelboards
and motor control centers. The SCCR covers
not only the overcurrent protective device in the
end-use equipment, but also the overall
construction of the equipment i.e. it is an
integrated equipment rating.
