In electrical terms, what does S.C. stand for when referring to short-circuit current rating?

Explanation:
S.C. stands for Short-Circuit. The short-circuit current rating is the maximum fault current that electrical equipment can safely withstand during a short-circuit without damage or unsafe conditions. This rating, usually given in kiloamperes, helps ensure the equipment can handle the fault current present at the installation without failing catastrophically. The other terms don’t fit standard electrical terminology here: Switch-Circuit isn’t a recognized term for this context, Static Current isn’t used to describe fault tolerance, and Surge Current describes transient overcurrents rather than the sustained fault current the rating protects against.
