In industries, selecting the wrong extension board can result in delays, costly damage to machinery, or serious electrical hazards. That’s why choosing the right industrial extension board is a strategic decision — based on load type, work environment, protection level, and portability.
To simplify your buying journey, here’s a step-by-step guide in a questionnaire format:
Step-by-Step Selection Guide
1. What type of board do you need?
Metal Box
- Ideal for heavy-duty outdoor/industrial environments
- Fire-resistant, robust, and heat-tolerant
Polycarbonate/Plastic Box
- Lightweight, corrosion-free
- Recommended for indoor or portable setups
Reel/Drum Type (Cable Reel Extension Board)
- For mobile tasks during shutdowns or maintenance
- Includes flexible heavy-duty cable
2. What kind of incoming protection is required?
- MCB (Miniature Circuit Breaker) – For overload protection
- RCBO (Residual Current + Overload) – Combines earth leakage + overload protection
- ELCB + MCB Combination – Separate leakage and overload safety
- RCCB (Residual Current Circuit Breaker) – Pure earth leakage protection
Recommendation: Use RCBO for compact, high-efficiency safety in portable boards.
3. What is your phase requirement?
- Single Phase (230V) – For lights, small motors, power tools
- Three Phase (415V) – For heavy machinery and industrial systems
- Combination Board – For mixed equipment setups
4. Which type of socket is required?
- Polycarbonate (Industrial Socket)
Durable, weatherproof, industrial-grade
- Metal Clad Socket
Heavy-duty, fixed installation, rugged
- Domestic Socket
5A/15A 5-pin sockets for light tools, lights, or office use
