Commercial electrical fault finding services in Ireland
Electrical faults in commercial and public buildings often involve larger, more complex systems than those found in homes. A registered electrician can carry out targeted tests using specialist tools to quickly diagnose and repair the issue. Common fault types include:
Tripping circuits and overloaded distribution boards
Frequent trips or fuses blowing may indicate overloading, faulty wiring, or degraded components. Electricians can test load balancing, circuit isolation and insulation resistance to locate the source of the problem.
Lighting faults and flickering systems
Flickering lights or unresponsive lighting systems could be due to loose connections, voltage fluctuations or ballast failures. Electricians can test and isolate faulty zones quickly to restore service safely.
Power supply issues
Sudden power loss or voltage drop in part of your premises may be linked to cabling faults, overloaded sockets, or upstream issues. Qualified electricians can test and trace affected circuits, including three-phase systems.
Heating and equipment control failures
Faults with electric heating systems, HVAC controls or automated equipment are common in schools, clinics, hospitality and retail units. Electricians can diagnose issues with thermostats, timers, sensors or heating cables using advanced testing tools.
Earthing, bonding and RCD faults
Protective devices such as RCDs must function correctly to prevent electric shock or equipment damage. Electricians can test earth continuity, loop impedance, and verify correct tripping thresholds to identify risks.
Thermal imaging (thermography)
For larger commercial buildings or complex distribution systems, thermal imaging can detect overheating components or hidden faults inside panels. This non-invasive technique is useful for preventative maintenance and safety checks.
Cable and underground fault location
Underground or inaccessible cabling in industrial units, outdoor areas or public grounds can be tested using signal tracing, resistance testing, and other advanced diagnostics to locate damage or faults without disruptive digging.
Why fault diagnostics matter for businesses and public buildings
Unresolved electrical faults can lead to safety issues, failed inspections, energy waste and costly downtime. Prompt diagnostics and repairs help you:
- Ensure compliance with Health & Safety regulations
- Prevent electrical fires or equipment damage
- Maintain business continuity and minimise disruption
- Prepare for inspections, insurance checks or lease handovers
- Extend the life of your electrical infrastructure
