In commercial buildings, the term “distribution board” (or DB) is more commonly used than fuse box – though both refer to the panel that distributes electrical supply to individual circuits. Modern commercial distribution boards use miniature circuit breakers (MCBs) and residual current devices (RCDs) rather than fuses, providing better protection and easier fault isolation. We install and upgrade commercial distribution boards to current BS 7671 standards. Call 0203 439 9474.
A commercial distribution board should be replaced when it contains rewireable fuses rather than MCBs, when it does not provide adequate RCD protection, when it is fully loaded with no spare ways for additional circuits, when it has been identified as faulty or non-compliant on an EICR, or when the building’s electrical load has grown beyond the capacity of the existing board. Call 0203 439 9474 for an assessment.
Yes. With careful planning, a commercial distribution board can often be replaced with minimal disruption – we typically programme the board replacement for a period of low occupancy or outside operating hours and restore power circuit by circuit as the new board is connected. For large buildings with multiple boards, we can replace boards individually over a series of visits. Call 0203 439 9474.
We supply and install commercial distribution boards as a fully managed service – selecting the appropriate board specification for your building’s load and circuit requirements and providing a complete supply and fit service including all associated cabling and containment. We also install client-supplied boards where required. Call 0203 439 9474.
On completion of a commercial distribution board replacement, we issue a Minor Works Certificate or an Installation Certificate depending on the scope of work, confirming the installation has been carried out and tested to BS 7671 standards. This documentation is required for insurance, Building Regulations compliance, and future sale of the property. Call 0203 439 9474.
