Introduction

This energy is primarily stored through a series of levers and gears that convert the movement of the circuit breaker into potential energy. 100% rated breakers may not be suitable for installation integral to all assemblies as referenced in the tables in this document. This code section is all about large frame circuit breakers where the highest continuous current trip setting for which the actual overcurrent device installed in a circuit breaker is rated or can be adjusted is 1200 A or higher. Think of it like a coiled spring in a jack-in-the-box—except here, the “pop” saves your equipment from damage.
