Welcome to Module 9, which is about miniature circuit breakers and supplementary protectors.

Typical Miniature Molded Case Circuit Breakers


Like the other modules in this series, this one presents small, manageable sections of new material followed by a series of questions about that material. Study the material carefully, and then answer the questions without referring back to what you've just read.
You are the best judge of how well you grasp the material. Review the material as often as you think necessary. The most important thing is establishing a solid foundation to build on as you move from topic to topic and module to module.
