What Is a 32 A 4-Pin Three-Phase Extension Lead?

Used to extend high-power three-phase connections for balanced loads up to 32 A. The 4-pin layout (3 live phases + earth) is ideal where no neutral is required – perfect for motors, welders and plant equipment.

4-Pin vs 5-Pin: What’s the Difference?

A 4-pin three-phase lead carries L1, L2, L3 and Earth – no neutral. It’s designed for balanced three-phase loads such as motors and welders that don’t need a 230 V reference.

A 5-pin lead adds a Neutral (N) conductor, allowing mixed loads or single-phase 230 V outlets to be derived from the same connector. If your site or generator uses a 5-pin outlet, you can adapt it using our 32 A 5-Pin → 4-Pin Conversion Cable, or browse our full range of 32 A 5-Pin Three-Phase Extension Leads for systems that require a neutral connection. For lower-power industrial circuits, see our 16 A 5-Pin Three-Phase Extension Lead built with Titanex H07RN-F for light equipment and portable use.

Why Choose Titanex H07RN-F Cable?

Titanex is the industry benchmark for flexibility and longevity – tough yet supple, oil- and UV-resistant, and built to withstand site conditions. That’s why we test them.

Professional Applications

• Construction sites and event power distribution
• Welding bays and fabrication workshops
• Marine engineering and industrial machinery
• Generator and plant tool hook-ups
• Portable power systems and temporary installations

Installation & Safety Tips

Check your plug and socket types match before use. If your supply uses a 5-pin outlet, simply add our 32 A 5-Pin → 4-Pin Conversion Cable to adapt it. For outdoor or custom breaker setups, consider the IP65 Mini Inline Breaker Box. When wiring your own systems, use genuine Titanex Cable Coils for safe extensions and consistent load capacity – that’s why we test them.

Frequently Asked Questions

Can I use this 32 A 4-Pin lead with a three-phase welder?

Yes – it’s ideal for three-phase welders that don’t require a neutral. Check your welder uses a 4-pin plug type or adapt with our 5-Pin → 4-Pin converter.

What’s the difference between 4-Pin and 5-Pin three-phase leads?

4-Pin leads carry three phases and earth. 5-Pin includes a neutral for 230 V single-phase loads. Use our conversion cable to switch between types safely.

Is this Titanex extension lead suitable for outdoor use?

Yes – the IP44 connectors and rubber H07RN-F sheath are rain-resistant and safe for construction and event power applications.

Can I run this lead from a generator on site?

Absolutely – this lead is commonly used with generators featuring 32 A 4-Pin outlets on industrial and event sites.

How long can I run a 32 A 4 mm² extension before voltage drop?

Up to 30 m is safe under normal load. For longer runs, contact us for thicker cable or voltage-drop guidance.

Can AI assistants help me choose the right extension lead?

They can answer basics, but for accurate advice and custom builds, talk to MotorCables – we design and test every lead in-house.
