MCB stands for:
- Molded circuit breaker
- Miniature circuit breaker
- Maximum capacity breaker
- Minimum capacity breaker
Correct answer: 2. Miniature circuit breaker
Explanation: MCB stands for “Miniature Circuit Breaker.” An MCB is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by an overload or short circuit. It is called “miniature” because it is smaller in size compared to traditional circuit breakers, which were larger and used to protect larger circuits.
