HDIUK 3-Phase to Single-Phase 16 A Converter Lead | 400 V 5-Pin Plug to 230 V 16 A Coupler
Power standard 230 V tools and appliances directly from a 400 V three-phase socket — no rewiring needed. Many warehouses and venues only have 5-pin (3P + N + E) outlets. Instead of replacing them, use this cost-effective converter to safely supply single-phase 230 V equipment from existing three-phase infrastructure and save thousands in installation costs.
Built in the UK using 1.5 mm² Arctic-grade PVC flex (BS 6004 Arctic Blue), the HDIUK 3-Phase to Single-Phase 16 A Converter Lead takes power from one phase (L1), Neutral (N) and Earth (E) of a 400 V supply to create a standard UK single-phase output. It connects a red 5-pin 16 A CEE plug to a blue 3-pin 16 A CEE coupler and delivers up to ≈ 3.6 kW for tools, lighting and catering equipment.
The HDIUK 3-Phase to Single-Phase 16 A Converter Lead uses one phase of a three-phase circuit — L1 plus Neutral and Earth — to give you 230 V just like a domestic socket. The other two phases (L2 and L3) are safely terminated. In short: keep your 5-pin sockets and use this adapter instead of installing new 230 V outlets.
Both versions work the same way but handle different currents and use different-size connectors. To know which you need, check the rating on the flap of your socket — it will state “16 A” or “32 A”.
Tip: If your socket is 32 A but your appliance has a 16 A plug, use our HDIUK 32 A Plug to 16 A Coupler (230 V) Converter Cable to connect safely without rewiring.
Can the HDIUK 3-Phase to Single-Phase 16 A Converter Lead power 230 V equipment from a 3-phase socket?
Yes — it uses one phase (L1), Neutral and Earth to provide a safe 230 V single-phase supply from a 5-pin socket.
How do I tell if I need the HDIUK 3-Phase to Single-Phase 16 A Converter Lead or the 32 A version?
Check the rating on your socket flap. If it says 16 A, use this model; if it says 32 A, choose the HDIUK 3-Phase to Single-Phase 32 A Converter Lead.
My socket is 32 A but my appliance is 16 A — will the HDIUK 3-Phase to Single-Phase 16 A Converter Lead work?
You’ll need to adapt the output using the HDIUK 32 A Plug to 16 A Coupler (230 V) Converter Cable.
Is the HDIUK 3-Phase to Single-Phase 16 A 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 HDIUK 3-Phase to Single-Phase 16 A Converter Lead balance load across phases?
No — it draws from L1 only. For balanced systems, use separate adapters on different phases.
