Twin RCD Metal Consumer Unit – WME22100TR (22 Module, 100A)

The WME22100TR is a 22-module metal twin RCD consumer unit with a 100A main switch, two 100A RCDs. It provides 16 usable ways for the outgoing circuit arrangement.

This is the standard 100A RCD version, supplied without an SPD. WCED lists the two 100A RCDs but does not specify their exact type or residual-current sensitivity in the matching product row. Confirm those details for the intended installation before ordering.

Please contact Power & Data UK for the exact supplied RCD type, residual-current sensitivity and assembly technical data. The /SP version has a separate documented specification.

The module count describes the enclosure format; usable ways describe the space available in the listed configuration. Confirm the required outgoing protective devices and their approved layout when ordering.

A qualified electrician must select, install and test the WME22100TR against the circuit design and the supplied assembly and device instructions.

• Plan the outgoing devices around the manufacturer's 16 usable ways and approved board/busbar arrangement.
• Check the main-switch, RCD and supply protective-device ratings. The ratings of two RCDs must not be added together to determine the board's permitted load.
• Confirm the exact fitted RCD type and residual-current sensitivity before installation.
• Assess the surge protection required for the installation; this version does not include an SPD.
• Follow the supplied mounting, cable-entry, earthing, terminal-capacity and tightening-torque instructions.
• Complete the required inspection, testing and circuit labelling before putting the board into service.

What does WME22100TR include?

The documented configuration includes a 100A main switch and 2 × 100A RCD protection, in a 22-module metal enclosure with 16 usable ways.

Why are there 16 usable ways in a 22-module enclosure?

The fitted incoming devices occupy part of the enclosure. WCED lists 16 usable ways for these standard 22-module twin RCD boards and 15 for the /SP versions. The final circuit count depends on the width and approved arrangement of the outgoing devices.

Which RCD type and sensitivity are supplied?

The matching manufacturer listing confirms two 100A RCDs but does not identify their type or residual-current sensitivity. Please contact Power & Data UK for confirmation.

Does it include surge protection?

No. The WME22100TR/SP version includes a Type 2 SPD and has 15 usable ways. Check its documented RCD specification as well as the SPD when comparing.
