Find the rating on the component label or manufacturer datasheet.
Do you want to calculate the short circuit current rating for a specific electrical system? I can guide you through the process. short circuit current rating calculator
The most common way to calculate a panel's overall SCCR is the provided by UL 508A Supplement SB. Find the rating on the component label or
Here is a simple short circuit current rating calculator formula: terminal blocks typically default to
: The overall SCCR for the entire panel is generally limited to the lowest SCCR of any individual component or branch circuit within that panel.
For unmarked components, use from UL 508A Table SB4.1 (e.g., terminal blocks typically default to
