### Interrupting Rating

* "short-circuit interrupting rating"

Applies to "Equipment intended to interrupt current".

[[nfpa-70_110_requirements#^9|NEC 110.9 Interrupting Rating.]]

Maximum current that the equipment can interrupt without damage.
Measured in amperes, usually shown as kAIC.

### Short-Circuit Current Rating (SCCR)

* "withstand rating"

[[nfpa-70_110_requirements#^10|NEC 110.10 Circuit Impedance, Short-Circuit Current Ratings, and Other Characteristics.]]

Applies to **assemblies**: distribution equipment
like switchboards, panelboards, switches, etc.

Maximum current that the equipment can withstand
in a short-circuit event without damage.
Measured in amperes, usually shown as kA.
