Sizing the Circuit Breakers rev.03 1 | Page Sizing the Circuit Breakers With the fixture’s current draw information, the installer can calculate and select the right circuit breaker size (rating) to which they can connect a group of fixtures. The following provides several methods that can be used. power circuit breakers. All UL ®, NEMA® and ANSI standards are for molded-case circuit breakers and low voltage power circuit breakers. The industry recognizes three types of circuit breakers— molded-case circuit breakers (MCCB), insulated-case circuit breakers (ICCB) and low voltage power circuit breakers LVPCB). circuit breakers must be at the same physical location as the service entrance to shut off panels located elsewhere in the building. 6/14/02 Chapter 3: NEC CODE Rules and Design Practice 10/13 . 6/14/02 Chapter 3: NEC CODE Rules and Design Practice 11/13 . BASIC NEC CODE RULES AND DESIGN PRACTICE 3 Molded-Case Circuit Breakers Molded-Case Circuit Breakers Molded-Case Circuit Breaker Family Product Description Eaton’s molded-case circuit breakers are designed to provide circuit protection for low voltage distribution systems. They are described by NEMA® as “a devcie for closing and interrupting a circuit between separable “back-up” protection and provide superb short circuit protection at the same time. LPJ_SP, TCF, and LP-CC fuses are sized a little larger but are even more current limiting, providing an even greater degree of short circuit protection for the motor circuit.
