The WME08/MS100 Main Switch Consumer Unit is an 8-module metal enclosure supplied with a 100A main switch incomer. It provides 6 usable ways, giving a little more room than smaller 2–4 way boards and making it well suited for medium-sized domestic installs, annexes, or workshops. Built from powder-coated steel with raised DIN rails and multiple knockouts, it’s a reliable and installer-friendly base ready for MCB or RCBO configuration.
Installer Tip: Choose the 6-way model when you need a little more flexibility than a garage board but don’t need a full-sized domestic unit. Perfect for small houses, extensions, or workshops with multiple circuits.
