What is short-circuit current rating?
The prospective symmetrical fault current at a nominal voltage to which an apparatus or
system is able to be connected without sustaining damage
What is selective coordination?
Achieved when only the OCPD directly upstream from the overcurrent opens to interrupt
the current, and no other upstream OCPD's open for all magnitudes of overcurrent.
What is a fully rated system?
System is one in which all of the overcurrent protective devices have an individual
interrupting rating at least as great as the available short-circuit current at their point of
application.
