Powermax SKTT-PMMN13 Socket
The Powermax Metal Twin Socket provides a high-durability power interface for demanding industrial and commercial environments. This unit features a heavy-duty metal clad construction to resist mechanical impact. Engineers specify this model for areas where plastic alternatives might suffer physical damage. The dual-gang configuration provides two independent 13A outlets within a single compact footprint. Each unit includes a matching surface-mount backbox for immediate installation. The steel enclosure undergoes a powder-coating process to resist corrosion and wear over long operational cycles.
Multiple 20mm knockouts are integrated into the sides and rear of the box. These entry points facilitate easy connection to standard electrical conduits. Internally, the outlet utilizes high-grade brass terminals for optimal conductivity. These terminals accommodate various cable gauges common in commercial wiring. The double-pole switching mechanism enhances user safety by isolating both the live and neutral feeds. This design minimizes the risk of electrical faults in heavy-duty applications. The assembly complies fully with BS 1363-2 standards. This certification ensures the hardware meets rigorous safety benchmarks for industrial electrical systems.
The flush-fitting front plate sits securely against the backbox to prevent dust ingress. This makes it suitable for workshops, garages, and plant rooms where airborne particles are present. The internal layout provides sufficient space for cable management. Installers can route wires without excessive bending or tension. Dual earth terminals are standard, supporting high-integrity earthing requirements for data processing equipment. This feature is critical for modern IT environments and industrial control centers. The grey finish provides a neutral aesthetic that fits technical spaces. The switch rockers have a positive tactile feedback, indicating a secure connection. This helps operators confirm the state of the power supply even when wearing work gloves. Additionally, the unit maintains structural integrity under temperature fluctuations common in non-climate-controlled zones. The mounting screws are standard M3.5 for universal compatibility.

Very sturdy sockets. Used these for my workshop in Industrial Area and they can handle the rough handling. The metal casing is thick enough and doesn’t bend easily like the cheap ones you find in downtown shops.

Good quality for the price. Arrived on time and working well so far.

Installed these in our small server room and the finish is quite neat. It’s a 2-gang so it saves space on the wall. Only small issue was one of the mounting screws in the box was slightly threaded, but the socket itself is 10/10. Very heavy duty.

Exactly what I needed for the heavy-duty extension I was building for the site. Most plastic ones break if you accidentally step on them or knock them with tools, but these Powermax metal clad ones are solid. Switched all my garage points to these SKTT-PMMN13 models. Great value for money and the 13A rating is genuine.
