Explain SCCR and how protective devices are coordinated to ensure selective tripping.

• A. Short-Circuit Current Rating; ensures equipment can withstand fault currents; coordination ensures upstream protective devices clear faults selectively to minimize downtime.
• B. Static Capacitive Current Rating.
• C. Sequential Circuit Current Rating.
• D. Surge Current Reduction Rating.
