The National Electrical Manufacturers Association (NEMA) published a white paper, NEMA ABP 3-2013 Molded Case Circuit Breaker Systems Testing with Conductors.

Molded case circuit breakers are designed to protect rated conductors and in particular, insulated wire. For this reason, it is necessary to test circuit break­ers with wire to demonstrate that protection. NEMA ABP 3 discusses the necessityto test circuit breakers with wire to demonstrate that protection. The standard tests (as defined in UL 489) include overload and thermal tests, endurance followed by low level short circuit interrupting tests, and standard low level short circuit interrupting tests.

NEMA ABP 3-2013 Molded Case Circuit Breaker Systems Testing with Conductors is available at no charge.
