The 5V DC 4.0A shared output across both USB ports handles simultaneous charging of phones, tablets and other USB-powered devices without needing a separate charger plugged into the mains outlets.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential kitchens, living rooms, bedrooms and home offices, the socket fits standard UK back boxes with a minimum depth of 25-35mm depending on wiring conditions. The rounded edge design includes a built-in gasket that sits flush against the wall, creating a sealed edge around the faceplate for a cleaner finish than traditional flat-edge plates. The single-pole switching isolates the live line when the socket is switched off, suitable for standard domestic appliance loads up to 3,120W per outlet.\u003c\/p\u003e\n\u003cp\u003eThe polished chrome finish provides a bright, reflective metallic surface that pairs with modern, contemporary and chrome-accented interiors. The black inserts behind the chrome faceplate define each outlet and switch aperture, while the black metal rocker switches maintain a consistent colour scheme across the plate. The premium-grade steel construction carries an IP20 rating for indoor use and a 2-year manufacturer warranty.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e85.75 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e146.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e7.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.

The 7.5mm faceplate projection is measured from the wall surface once installed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the USB charging output?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe socket provides 5V DC at 4.0A shared across both USB ports. When both ports are in use simultaneously, the 4.0A output is divided between the connected devices. Knightsbridge recommends using certified USB cables for safety and optimal charging performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between single-pole and double-pole switching?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis socket uses single-pole (SP) switching, which isolates only the live line when switched off. Double-pole (DP) switching isolates both live and neutral, providing additional safety for high-draw appliances. For most domestic loads, SP switching is sufficient.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat other finishes are available in this range?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eKnightsbridge produces this rounded edge style in multiple finishes including brushed chrome, polished brass, antique brass, matt black and white.
