Fault finding & diagnostics

Overview

Fault finding is a process of elimination. We isolate circuits, test insulation and continuity, and work through the system until the actual cause is found — whether that’s a failing appliance, moisture in a fitting, a damaged cable or an overloaded circuit.

Once we know the cause, we explain it in plain language and give you clear options to fix it.

What it involves

• Circuit isolation and systematic testing
• Insulation resistance testing
• Continuity and polarity checks
• Safety switch (RCD) trip investigation
• Load and overload assessment
• Appliance and equipment fault isolation
• Intermittent and moisture-related faults
• Clear written findings and recommendations

Who it’s for

Common problems we solve

• Safety switch trips with no obvious cause
• Power goes out when it rains
• A circuit that keeps tripping under load
• Intermittent faults that disappear when someone arrives
• Burning smells or warm spots with no visible damage

Why use a licensed electrical contractor

Guesswork costs money. Proper diagnostic testing finds the actual fault, so you pay to fix the problem once — rather than replacing parts until the symptom goes away.
