The WPMS04/620 is a factory-built IP65 plastic garage enclosure fitted with a 100 A main switch incomer and twin B Curve MCBs rated at 6 A and 20 A. Designed for garages, workshops, and garden buildings, this unit provides safe and compliant weatherproof distribution for lighting and medium-load circuits.

Installer Tip: The 6 A / 20 A combination works perfectly for small power setups — one circuit for lighting, and one for tools, sockets, or heaters. For heavier equipment, use the 32 A version.
