### Interrupting Rating
|
|
|
|
* "short-circuit interrupting rating"
|
|
|
|
Applies to "Equipment intended to interrupt current".
|
|
|
|
[[nfpa-70_110_requirements#110.9 Interrupting Rating.|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#110.10 Circuit Impedance, Short-Circuit Current Ratings, and Other Characteristics.|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.
