The WMMS/632 is a robust IP40 metal garage consumer unit fitted with a 100A main switch incomer and pre-installed 6A and 32A B-curve MCBs. Designed for garages, workshops, and outbuildings that need a separate lighting circuit plus a high-load circuit for equipment such as welders, compressors, or heaters, it meets BS 7671:2018 Amendment 2 requirements for safe local isolation and circuit protection.
Use the 6A breaker for lighting and the 32A breaker for heavy-duty radial or equipment circuits. The all-metal IP40 enclosure, earthed lid and integrated neutral/earth bars ensure a safe, clean, and installer-friendly setup that’s ready for inspection and certification.
Installer Tip: The 32A circuit suits single-phase loads up to around 7.3 kW. Check cable sizing, protective coordination and maximum demand to maintain compliance with BS 7671 disconnection times and voltage drop limits.
