SCCR is measured in kiloamperes (kA) and each component in a panel is labeled from the moment of installation.
Web28 de abr. de 2024 · How is the SCCR calculated? There are three steps in the process: Step 1 – Determine the short circuit current rating (SCCR) of each component or combination in the power circuit. (SB4.2) Step 2 – Determine whether feeder circuit components limit fault current (SB4.3) circuitprotective devices, like the fuse.
WebStep 2. Determine the SCCR value for all components in the power circuit. • SCCR is usually marked on the component, combination ratings are available on the UL website, or with the manufacturer’s instructions. • If not available from the manufacturer, the SCCR value can be determined by using UL Table SB4.1 (see Appendix).
