Frequently Asked Questions (FAQs)

Q: What is a circuit breaker used for?
A: A circuit breaker is used to protect an electrical circuit by automatically interrupting current flow when an overload, short circuit, or electrical fault occurs.

Q: What’s the difference between MCB and MCCB?
A: MCBs (Miniature Circuit Breakers) are used for low‑current household and light commercial circuits, while MCCBs (Molded Case Circuit Breakers) handle higher current loads and are typically used in commercial and industrial systems.

Q: Do circuit breakers reset after tripping?
A: Yes. After resolving the fault condition, most circuit breakers can be manually reset to restore normal operation. Always ensure the issue is corrected before resetting.

Q: Can I install circuit breakers myself?
A: Only if you are a qualified electrician or familiar with electrical codes and safety practices. Improper installation can be dangerous — we recommend professional installation for safety and compliance.
