Professional Electrical Fault Finding
Electrical faults can be disruptive and, in some cases, unsafe. Marsh & Co approaches fault finding systematically — using proper test equipment to identify the root cause rather than guessing. This means the actual problem is resolved, not just the symptom.
Fault Finding
Common faults we investigate
- Tripping circuits and nuisance tripping
- RCD and RCBO faults
- Loss of power to part or all of a property
- Lighting faults and flickering lights
- Socket faults and dead sockets
- Intermittent electrical problems
Systematic, not guesswork
Every fault-finding visit begins with testing. Using calibrated multi-meters and insulation testers, each affected circuit is checked for continuity, insulation resistance, polarity and earth fault loop impedance. This methodical approach pinpoints the fault quickly, keeps costs down, and ensures the repair addresses the genuine cause.
Clear explanation and repair
Once the fault is identified, you'll be told what's wrong, what's needed to put it right, and the cost before any further work begins. Repairs are carried out, tested, and certified where required. You're left with a safe, working installation and a clear understanding of what was done.
