Confidence is built
into the detail.
The right switchboard has to work for the people who specify it, install it and maintain it. That is where our manufacturing experience counts.
A layout that works
Keep the detail
connected.
Design, metalwork, assembly, wiring and identification come together through the CWS workshop. Drawings and construction stay part of the same conversation.
Know what you are
bringing to site.
Factory checks, agreed functional testing and project records support the handover. Talk through the inspection and acceptance requirements with us early.

Resolve the detail early.
Loads, fault levels, cable access and site space shape the board before manufacture. Work through the layout while changes are still on the drawing.

The enclosure, busbar layout and cable zones come together around your specification, with installation and future access considered in the arrangement.

Wiring, identification and terminations are coordinated with the drawings so the board is practical to connect and maintain.
