Description

The Knightsbridge SN9931D is a 13A 2-gang DP switched socket with one USB-A and one USB-C charging port built into a white square edge faceplate. 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.

Designed 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.

The 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.

Frequently Asked

What back box depth is required?

A minimum 25mm back box depth is needed, though 35mm is recommended where cable volume is higher or where multiple cables enter the back box. The socket projection is 7mm from the wall surface once fitted.

What's the USB charging output?

The USB ports deliver a combined 5V DC 3.1A output. This is shared between the USB-A and USB-C ports, so charging speed will be slower when both ports are in use simultaneously compared to charging a single device.

What does the anti-microbial protection do?

The thermoset resin plate is treated with an anti-microbial additive tested to ISO 22196:2011, which reduces bacterial growth on the surface. This is useful in kitchens, bathrooms and public-facing installations where the socket is touched frequently.

Is this a screwless faceplate?

No. The square edge plate is a traditional screw-fixed design with visible fixing screws. For a screwless version of this socket, search Knightsbridge's screwless range at Niori.
