Understanding Your Commercial Fuse Board: When to Upgrade
Your fuse board — or consumer unit — is the heart of your electrical system. It distributes power to every circuit in your building and provides critical protection against overloads, short circuits, and electric shocks. If it's outdated, your entire premises could be at risk.
Signs Your Fuse Board Needs Upgrading
- It still uses rewirable fuses rather than modern MCBs
- There's no RCD protection installed
- You experience frequent tripping or blown fuses
- The board is warm to the touch or shows signs of scorching
- You're adding new circuits or increasing electrical load
What Does a Modern Consumer Unit Include?
A modern commercial consumer unit features MCBs (miniature circuit breakers) for overload protection, RCDs (residual current devices) for earth fault protection, and surge protection devices. They're housed in non-combustible enclosures as required by the 18th Edition Wiring Regulations. This is a key part of our commercial installation service.
The Upgrade Process
A fuse board upgrade typically takes a day for most commercial premises. Our electricians will isolate the supply, remove the old board, install the new unit, and thoroughly test every circuit. You'll receive full certification and an electrical installation certificate on completion.
