How To — Calculate Sccr

The Short-Circuit Current Rating (SCCR) represents the maximum level of short-circuit current an electrical component or assembly can safely withstand without causing a shock, fire, or structural hazard. Under NEC (National Electrical Code) Article 409, calculating and marking the SCCR on industrial control panels is a mandatory safety requirement. Step 1: Identify Individual Component Ratings

Ensure that your SCCR is equal to or greater than the available fault current at the point of installation. If it isn't, your pane...
