Installation is quick and electrician-friendly – the unit features large rear and side keyhole mounting slots and ample wiring space for tidy routing of cables. Multiple knockouts (20mm, 25mm, 32mm sizes) are provided on the top, bottom, sides, and rear for flexible cable entry or trunking in any direction . An integrated spirit level and a floating/busbar assembly ensure a level, hassle-free installation and easy alignment of MCBs . The interior layout includes separate, clearly marked earth and neutral terminal bars along the top for neat wiring and identification of circuits.

Built for safety and durability, the Axiom MCU16S uses a full metal construction with a drop-down hinged cover door to contain arcs or sparks, impeding fire entry in the event of a fault . It meets BS EN 61439-3 and IET regulation 421.1.201 requirements for domestic consumer units, so you can install with confidence that it’s up to the latest standards . The enclosure is finished in an attractive, neutral powder-coat (white/grey) that is low smoke & fume, making it suitable for internal installation in homes, offices or workshops without an eyesore. A 1-year warranty is included from the manufacturer for peace of mind.

This 14-way fuse box is ideal for anyone upgrading an old fuse board or undertaking a new build needing a compliant distribution board. Its “14 free ways” design means you can populate it with up to 14 MCBs or RCBOs of your choice (not included) to protect individual circuits – perfect for modern homes with many circuits (lighting, sockets, cooker, EV charger, etc.). Electricians appreciate the Axiom’s modern, user-friendly design – it’s “quick and easy to install” and provides a “comprehensive circuit protection solution with a stylish contemporary design” comparable to more expensive brands, but at a competitive price.
