Twin RCD Metal Consumer Unit – WME2280TR/SP (22 Module, 80A, with Surge Protection)

The WME2280TR/SP is a 22-module metal twin RCD consumer unit with a 100A main switch, two 80A, 30mA Type AC RCDs and a Type 2 surge protection device (SPD). It provides 15 usable ways for the outgoing circuit arrangement.

This is the surge-protected 80A RCD version. WCED specifies Type AC residual-current protection at 30mA for this model. Select the RCD type and outgoing devices against the connected loads and the circuit design; an included SPD does not establish suitability for every application.

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 WME2280TR/SP against the circuit design and the supplied assembly and device instructions.

• Plan the outgoing devices around the manufacturer's 15 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 that 30mA Type AC RCD protection is appropriate for the connected loads and required disconnection performance.
• Follow the supplied SPD wiring, conductor and protective-device coordination instructions.
• 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 WME2280TR/SP include?

The documented configuration includes a 100A main switch and 2 × 80A, 30mA Type AC RCD protection plus a Type 2 SPD, in a 22-module metal enclosure with 15 usable ways.

Why are there 15 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 is fitted?

WCED specifies two 80A, 30mA Type AC RCDs for WME2280TR/SP. The RCD type must suit the connected loads; it should not be assumed from another model in the range.

Does the SPD make this suitable for EV or solar circuits?

The Type 2 SPD provides surge protection. The installation still needs the appropriate residual-current, overcurrent and any other application-specific protection. Confirm the complete design before selecting this board.
