Description
Use this 3-Phase to Single Phase 16A 5-Pin Red Plug to 16A 230v Coupler when you need to connect 230V equipment to a 400V three-phase socket without rewiring. It allows you to utilize existing infrastructure, making it a cost-effective solution for powering tools and appliances directly.

What This Is For
This converter lead is perfect for workshops, warehouses, and event venues that primarily use 5-pin (3P + N + E) three-phase sockets. Instead of replacing these sockets, you can safely supply single-phase 230V equipment, thereby saving on installation costs.

Compatibility & Safety Notes
Before use, check that your socket is rated for 16A. The lead draws power from one phase (L1), along with Neutral and Earth, to supply 230V. It is not designed to balance load across phases, so for balanced systems, use separate adapters on different phases. The connectors are IP44 rated, making them suitable for temporary outdoor applications.
Frequently Asked Questions
Can the 3-Phase to Single Phase 16A Converter Lead power 230V equipment from a 3-phase socket?
Yes, it uses one phase (L1), Neutral, and Earth to provide a safe 230V single-phase supply from a 5-pin socket.
How do I tell if I need the 16A Converter Lead or the 32A version?
Check the rating on your socket flap. If it says 16A, use this model; if it says 32A, choose the 32A version.
My socket is 32A but my appliance is 16A — will the 16A Converter Lead work?
This lead has a 16 A input plug and will not directly fit a 32 A outlet. Use an appropriately rated and protected adapter arrangement; the 16 A side must remain protected to its rating.
Is the 16A Converter Lead suitable for outdoor or site use?
Yes, it uses IP44 CEE connectors and Arctic Blue PVC flex designed for temporary outdoor applications.
Does the 16A Converter Lead balance load across phases?
No, it draws from L1 only. For balanced systems, use separate adapters on different phases.
