What does the abbreviation ICCB stand for in electrical safety?

The abbreviation ICCB stands for Insulated Case Circuit Breaker. This type of circuit breaker is designed to provide overcurrent and overload protection for electrical circuits. The "insulated case" refers to the protective casing that encloses the internal components of the breaker, which helps to ensure safety and reliability in various electrical systems.

Insulated case circuit breakers are important in industrial settings where they are used to protect larger electrical motors and other significant equipment. They are capable of interrupting high fault currents and are often designed with adjustable trip settings to suit different load conditions, making them versatile for various applications.

The other options, while sounding plausible, do not accurately describe what ICCB stands for and are not standard terminology in the context of electrical safety. Understanding the correct definition is crucial for maintaining safety and effective practices within electrical work environments.
