An MCB is not just an on/off switch — it is a safety device that protects your wiring and appliances from damage caused by overload or short circuits.

MCBs are available in ratings such as 6A, 10A, 16A, 20A, 32A, etc.
• 6A / 10A – Lights, fans, small load points.
• 16A / 20A – Medium appliances like geysers, washing machines, microwaves.
• 32A and above – Heavy appliances like ACs, water heaters, and kitchen equipment.
Choosing the wrong rating can cause nuisance tripping (too low) or failure to trip in time (too high).

Each circuit has different load requirements. If one high rating MCB is used everywhere, it may not trip on time, risking damage. If one low rating is used everywhere, it will trip repeatedly, causing inconvenience.

MCBs mainly protect equipment and wiring. For protection against electric shock, an RCCB is required.

No. MCBs are not designed for daily switching. They are protection devices. Use modular switches for regular on/off control.

It means either the rating is incorrect or the circuit is overloaded. Get it checked by a qualified electrician.

Non-standard products may fail to trip on time, risking fire or accidents. Always choose ISI-certified brands.

Electricians often recommend what is cheapest or easiest to source. But switchgear is a life-saving device. Always insist on trusted brands with safety certifications.

We strongly recommend Vinay Switchgear for reliability and proven quality. But more importantly, we urge consumers to install any standard, certified MCB — because safety comes first.

To save money, some builders use low-grade MCBs and DBs in projects. We strongly advise homeowners to upgrade to high-quality certified products immediately.

Your MCB is not just a switch — it is your first line of defense against electrical accidents. Never compromise. Whether you choose Vinay or another reputed brand, make sure your switchgear is certified, tested, and trusted.
