Commercial fuse board and distribution services in Ireland
Commercial and public buildings have more complex electrical demands than domestic properties. Electricians with commercial experience can design and install distribution systems that meet these demands safely and efficiently:
Fuse board installation and upgrades
Replace outdated or overloaded fuse boards with modern distribution panels that offer circuit protection, clear labelling, and room for future expansion. Boards are installed to Safe Electric standards and can support 3-phase systems where required.
Sub-distribution boards
Larger buildings often require multiple sub-boards to manage power distribution to different zones, floors, or departments. Electricians can install and configure sub-distribution units to prevent overloads and improve control over electrical zones.
Three-phase supply and load balancing
Most commercial premises in Ireland rely on three-phase supply for high-power equipment, lifts, heating or air conditioning. Electricians can install or upgrade 3-phase panels and check load distribution across phases to prevent tripping or unbalanced loads.
Surge protection devices (SPDs)
Surge protection is increasingly recommended — or required — for sensitive commercial equipment and lighting systems. Electricians can integrate SPDs into the distribution board to protect your systems from voltage spikes and lightning strikes.
Residual current devices (RCDs) and MCBs
Ensure staff and customers are protected with properly rated residual current devices (RCDs) and miniature circuit breakers (MCBs). These components are critical in preventing electric shock, fire hazards, and appliance damage.
Meter board and main supply isolation
For larger premises, electricians can install or relocate meter boards, isolators and main switches — ensuring your site complies with ESB and fire safety access requirements.
Testing and certification
All distribution board work is followed up with testing, labelling and official certification. Electricians can provide Completion Certificates, testing reports and ESB notification where required.
Why upgrade your commercial fuse board?
Many older commercial buildings in Ireland still operate with outdated or overloaded boards that no longer meet modern safety and operational needs. Upgrading can help:
- Prevent frequent tripping or unexplained outages
- Prepare for additional equipment, EV chargers or IT systems
- Reduce the risk of fire caused by overheating circuits
- Ensure compliance with insurance and workplace safety standards
- Allow for easier maintenance and zoning
