The dual-pole switching isolates both live and neutral lines when the socket is switched off, providing additional safety for appliances and equipment. The USB ports deliver a combined 5V DC 3.1A output for simultaneous charging of phones, tablets and other devices without occupying the mains outlets.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential, office and light commercial installation, the socket fits a 25-35mm back box depending on cable volume and wiring conditions. The square edge plate sits flush to the wall with a 9mm profile, giving a clean contemporary finish that works across both domestic and commercial settings. Top-access captive terminals speed up installation and reduce the risk of loose connections during fitting.\u003c\/p\u003e\n\u003cp\u003eThe thermoset resin plate incorporates anti-microbial protection tested to ISO 22196:2011, reducing bacterial growth on the surface in high-touch environments like kitchens, bathrooms and public-facing areas. The white finish matches standard decorator white and pairs with most wall colours. Twin earth terminals provide secure grounding for Class I installations, and the IP20 rating makes the socket suitable for dry indoor locations.\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\u003e86 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e146 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e7 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
