Description
Convert 400 V 3-phase power to 240 V UK mains instantly with this professional-grade HDIUK Phase-1 Fly-Lead Converter. It safely adapts a red 5-pin 400 V CEE plug to twin 13 A UK sockets, providing single-phase 230–240 V output wherever only 3-phase supply is available. Ideal for workshops, catering units, events, and generator setups.
Reliable 400 V to 240 V Power Conversion
Built for industrial and event environments, this converter extracts a single phase (L1 + N + E) from a 3-phase socket to provide standard UK mains output. Assembled in the UK using Arctic-grade HO7RN-F cable and precision-moulded connectors, it ensures safe, stable power distribution on site.
Key Features
- Input: 400 V 3-Phase CEE Red Plug (5-pin IEC 60309)
- Output: Twin UK 13 A Sockets (BS 1363)
- Cable: Heavy-duty HO7RN-F rubber flex for industrial durability and flexibility
- Use Cases: Catering vans, mobile engineers, stage equipment and site power
- Safety Note: Sockets are not individually fused — each UK plug must contain a 13 A fuse
- Built & Tested: Professionally assembled and PAT tested in the UK
- Options: Available with either 16 A or 32 A CEE plug — check the rating inside your socket flap before ordering
Safe and Simple Power Adaptation
The HDIUK Phase-1 converter uses one live phase (L1), neutral and earth from a 5-pin 400 V socket to create a stable 230 V single-phase supply. Both sockets share the same phase, making this ideal for two moderate-load appliances such as lighting or tools rated up to 13 A each.
Use with 3-Phase Extension Leads
If your 400 V socket is some distance away, pair this converter with our HDIUK 16 A 3-Phase CEE Extension Lead or the HDIUK 32 A 3-Phase CEE Extension Lead. Both extend your red 5-pin 3-phase supply safely using Arctic-grade cable and IP44 connectors — perfect for generators, distribution boxes, and temporary event power.

Frequently Asked Questions
What is the difference between 16 A and 32 A CEE plug sizes?
The difference is capacity and size. A 16 A CEE plug is smaller and rated up to 16 amps, while a 32 A CEE plug is larger with thicker pins and cable to handle heavier loads up to 32 amps.
Can I use this converter on any 400 V 3-phase socket?
This converter is for standard red 5-pin (3P + N + E) 400 V CEE sockets. It uses only L1, Neutral and Earth, so confirm that the socket provides a neutral line before use. If unsure, consult a qualified electrician.
Is it safe to run 13 A UK appliances from a 3-phase plug?
Yes — when using a professionally built and PAT-tested converter like this. It provides a safe single-phase 230–240 V supply from L1, Neutral and Earth. Each UK plug must include its own internal 13 A fuse.
