⚡ Why Choosing the Right RCCB Matters
An RCCB is not just another switch in your DB panel. It is your first line of defense against electric shock and fire. A wrong RCCB rating or type can cause nuisance tripping, overheating, or no protection at all.
As an electrician working daily with home and commercial wiring, I always recommend selecting RCCB based on:
- Load capacity
- Leakage sensitivity
- Appliance type
- Future expansion
This guide will help you buy the correct RCCB with confidence.
