How to Choose the Right Industrial Extension Board for Your Plant or Project

✅ How to Choose the Right Industrial Extension Board for Your Plant or Project

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

IP Rating

• ☐ IP44 – Splash resistant
• ☐ IP66 – Fully dustproof and weatherproof

Socket Current and Pin Configuration

• ☐ 16A 3-Pin (Single Phase)
• ☐ 16A 5-Pin (Three Phase)
• ☐ 32A 3-Pin (Single Phase)
• ☐ 32A 5-Pin (Three Phase)
• ☐ 63A 5-Pin (Heavy Industrial Use)

---

🔹 6. How many sockets are needed on the board?

• ☐ 2 Socket Outlets
• ☐ 4 Socket Outlets
• ☐ 6 Socket Outlets
• ☐ Custom Configuration (Mix of 16A, 32A, domestic + industrial)

---

🔹 7. Do you require mobility or wall-mounting?

• ☐ Wall-mounted Panel
• ☐ Portable with Handle
• ☐ Cable Reel (Heavy-Duty)
