MS HD Power 13A UK Mains Plugs now available from MCRU, all the plugs have the same design with different plating options. This is the pure copper version with polished copper contact pins.

Available in 4 different finishes, all with every contact surface plated in the chosen finish.

Patented UK 3 pin mains plug with polished pins, securing up to 16mm diameter cables and up to 4mm power and earth conductors internally.


This high quality UK 13A 3 pin plug has been designed to be used with audio equipment power cables for the best power transmission with no compromises. All the electrical parts (polished pins and all internal parts) are made from premium quality copper, the Fuse Clips are made of high spring rate Phosphor Bronze - and supplied fitted with a high quality 13A silver plated fuse.

The patented design allows for easy cable fitting (instructions provided) and the ease of cable fitting cannot be under estimated, some other brands are difficult to wire up with thicker cables.

The plug casing is manufactured from nylon material, offering durability, high insulation, light weight and good looks.

The heavy duty mains wire-clamps design ensure an air tight connection to ensure perfect power transmission and also protect the power cable wires from damage over time - inferior plugs secure the cables by the grub screws twisting down onto the cable directly and can be prone to material 'creep' over time, causing damage. 

Compliance with: BS-1363 (plug), BS-1362 (fuse).

Mains voltage rating: 200~240 VAC x 13A

Size (Housing Only): Width 68mm, Depth 33mm, Height 68mm (inc. cable clamp)

Excellent product and a great combination with the oyaide cable and furutech iec. I reckon this combination can compete with much dearer ready made power cables.

This really made a difference for me(copper version)

Aside from the practical benefits this plug brings, in allowing the fitting of very thick cables, I was very pleasantly surprised by the sonic benefits - bass was certainly firmer, tighter and clearer, in fact the whole spectrum sounded like it had been given a spring clean and polish. Lyrics that had previously been a little difficult to make out were now lucid, and grating noise effects became tolerable, but without any lessening of dynamics, in fact an improvement in that area. In case you think this is just a case of overactive imagination, I had two exact runs of cable with the same IEC, but different plug, so I could make a valid comparison. The other plug was a silver plated MK, both plugs using the same silver plated Busman fuse. Results could vary depending on your mains quality and existing cabling, but for me, it certainly did the trick. I got an even better result after switching the Cratos power cable for the new Furutech nano cable.
