The WME22/MS100 Main Switch Consumer Unit is the largest in the range — a 22-module metal enclosure with a 100A main switch incomer. With 20 usable ways, it provides maximum capacity for full domestic rewires, HMOs, or small commercial installations. Built in powder-coated steel and supplied with raised DIN rails, pre-fitted earth/neutral bars, and multiple knockouts, it’s fully compliant and installer-ready.
Installer Tip: A 20-way board ensures future-proofing for even the largest homes or commercial sites, giving ample spare ways for EV chargers, solar PV, or additional circuits.
