Overload current is True
confined to the normal
conductive path
provided by the
conductors, circuit
devices, and loads
of the distribution
system.
Fault current ? the flows outside
normal conducting
path.
Because of the ? low
,impedance path, a
3- phase bolted
short-circuit
condition is
typically assumed to
be the highest level of
fault current.
Which one of the Branch-circuit overcurrent protective

is NOT correct per the specific devices they are intended
the Article 100 to protect.
definition of
branch-circuit
overcurrent
protective device?
Supplementary False
overcurrent
protective devices
are permitted to
be used as a
substitute for a
branch-circuit
OCPD or where a
branch-circuit OCPD
is required (per
,240.10).
A ? overcurrent current-limiting
protective device is
one
that clears a fault
current in one half
cycle or less and
reduces the
amount of fault
current let-through.
, When fault current True
is within the current-
limiting range of a
current-limiting
OCPD, the thermal
energy and
magnetic
(mechanical)
forces can be
greatly reduced. The
levels of both
thermal energy and
magnetic forces
are proportional to
the square of the
fault current that
flows.
A 600-volt or less True
branch-circuit
OCPD can be
identified as being
current limiting by
being marked "current
limiting."
The voltage rating False
