Compatibility & Safety Notes

Ensure that your plug and socket types match before use. If your supply uses a 5-pin outlet, you can adapt it using a 32 A 5-Pin → 4-Pin Conversion Cable. For outdoor or custom breaker setups, consider using an IP65 Mini Inline Breaker Box. Always use genuine Titanex Cable Coils for safe extensions and consistent load capacity.

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?
