How to Choose the Right MCB DB Box for Your Home
Published on November 9, 2025

Understanding Your Needs
Choosing an MCB Distribution Box (DB Box) is simpler than it looks. It all comes down to two key factors: size (number of ways) and type (single-door, double-door).
1. Count Your Circuits
First, count the number of circuits (e.g., lights, power outlets, AC) you need to protect. Each circuit needs one MCB. It's always smart to choose a box with a few extra "ways" (slots) for future expansion. A 12-Way box is a common choice for a standard home.
2. Choose a Type
Single-Door: Sleek and simple, ideal for most residential uses.
Double-Door: Offers extra protection, often with a transparent cover to see the MCB status without opening it. This is great for industrial or high-traffic areas.
