Description

The Knightsbridge NETBTSWH is a 25 x 50mm BT secondary telephone outlet module designed to fit standard euro-module faceplates. It uses insulation displacement contact (IDC) terminals for quick, tool-free connection of telephone cable cores without stripping the wire insulation. The module is certified to BS 5733, the British Standard for telecommunications installations.

Designed as an extension socket rather than a master outlet, this module connects to existing BT wiring to provide additional telephone points in offices, hotel rooms, care homes and residential properties. The 25 x 50mm dimension is a single euro-module width, allowing it to be combined with other modules (data, switches, sockets) in multi-gang grid systems. The module requires a minimum 25mm back box depth for installation.

The white ABS construction matches standard white faceplates and grid frames across the Knightsbridge modular range. The IDC terminals accept solid-core telephone cable (typically CW1308 or equivalent) and grip the cores without requiring screw terminals or crimping. The IP20 rating confirms the module is suitable for dry indoor locations but not bathrooms or outdoor use.

Frequently Asked

What is the difference between a secondary outlet and a master socket?

A master socket connects directly to the incoming BT line and typically includes surge protection and the network termination point. A secondary outlet like this module extends from existing wiring to provide additional telephone points within the building. It does not include line filtering or termination components.

What are IDC terminals?

IDC stands for insulation displacement contact. These terminals have blades that cut through the cable insulation when the wire is pressed into the terminal block, making contact with the copper core without needing to strip the wire first. This speeds up installation and reduces wiring errors.

Can this module be used in a bathroom?

No. The IP20 rating means the module is suitable for dry indoor locations only. Bathrooms require modules with higher IP ratings (typically IP44 or above) due to the presence of water and moisture.

What faceplate does it fit?

The module fits standard euro-module grid systems. Knightsbridge produces compatible grid faceplates in 1-gang, 2-gang and larger configurations across various finishes. The 25 x 50mm footprint is a single module width, so two of these modules would fit a 2-gang grid plate.
