Choosing the Right Consumer Unit Enclosure
Consumer unit enclosures protect the heart of your electrical installation. Choosing the right one means balancing environmental conditions with compliance under BS 7671:
- Domestic installs – metal-clad enclosures with non-combustible housings are now standard under UK wiring regulations. A reliable choice is the 4 Usable Way Consumer Unit, ideal for small household circuits.
- Outdoor/garage use – Garage consumer units or IP65/IP66 weatherproof enclosures guard against dust and moisture. For straightforward fit-outs, see the IP40 Metal Garage Unit with Main Switch.
- EV charging – EV-ready enclosures with PME protection or RCBOs give safe isolation for dedicated charge points. Installers often choose the 4-Way EV Protection Unit, which combines Type A RCBO and SPD in one enclosure.
- Commercial switchgear – higher current ratings and modular capacity from our three-phase boards provide flexibility for larger installs. For example, the 125A 3-Phase Distribution Board offers scalable protection for workshops and plantrooms.
Applications & Compliance
From small RCD enclosures for lighting circuits to larger distribution boards in workshops, all units in this range comply with 18th Edition standards. Clear labelling and multiple knockout options make installation straightforward.
