100A Main Switch Consumer Units – Buying Advice

Not sure which 100A main switch consumer unit you need? These boards provide a simple, central isolator for the whole installation, with circuit protection configured to suit the job—making them a popular choice for straightforward domestic and light commercial distributions. On this page you can filter by brand (including FuseBox, Hager, Live Electrical, Niglon and WCED) plus key fit-and-finish details like usable ways, depth/height, and practical features such as flush mounting, dual/triple row layouts, and round knockouts.

Quick buying checklist:

  • Count your circuits, then allow a couple of spare ways for future additions
  • Decide on your preferred protection setup (e.g., RCBO configuration vs RCD main switch options)
  • Check mounting style (surface vs flush) and dimensions to match the install location
  • Look for enclosure and knockout style that suits your cable entries and glanding

If you’re working to current wiring standards, it’s also worth considering broader protection requirements (for example RCD use, coordination with surge protection where needed, and AFDD recommendations in specific situations) and having the unit specified and installed by a qualified electrician.
