P Rating: Boxes with higher ingress protection (IP65 or IP66) for outdoor or harsh environments cost more than standard indoor-rated boxes. Size and Capacity: Larger boxes designed for multiple circuits or three-phase systems are priced higher. Residential models with fewer circuits are generally at the lower end of the price range.

Features: Inclusion of MCBs, RCDs, or RCBOs, as well as modular or customizable designs, increases the price.

Tips for Choosing

Match the IP rating to the installation environment (IP54 for indoor, IP65/IP66 for outdoor). Consider material based on corrosion exposure. Ensure the number of circuits and amperage meets your current and future needs.

Check for pre-installed breakers or RCDs if you want a ready-to-use solution. By considering these factors, you can select a double-door electrical distribution box that balances cost, durability, and functionality.
