When Something's Wrong But You Don't Know What
Electrical faults are frustrating — the RCD trips at random, half the lights work and half don't, the bedroom power point arcs occasionally, or the whole circuit is dead. Our Sparky specialises in proper fault diagnosis: insulation resistance testing, earth fault loop impedance, RCD trip current measurement, thermal imaging where needed — calibrated test gear that finds the actual fault rather than the nearest plausible thing to replace.
Most common faults we find in Hervey Bay homes: water ingress in outdoor power points (salt air + summer storms = constant culprit), failed appliances pulling earth leakage and tripping the whole-house RCD, degraded TPS cabling in roof spaces from heat and rodents, undersized cabling on heavy modern loads (induction cooktop on a 1980s circuit), and aluminium-to-copper joints corroding in older homes.
We charge a fixed diagnosis fee — credited toward repair if you proceed — and quote repair options separately. No 'we replaced this and it didn't fix it, so try this next' open-ended bills.
Our Services
RCD / Safety Switch Tripping Diagnosis
Find which circuit and which appliance is causing the trip — using systematic isolation, not guesswork.
Dead Circuit Diagnosis
Tracing breaks in cabling, failed connections, faulty switches and joints. Includes wall/ceiling tracing where needed.
Intermittent Fault Investigation
The hardest faults to find — we use data loggers and thermal imaging to catch faults that only appear sometimes.
Switchboard Diagnosis
Hot breakers, buzzing switchboards, smelling burning — proper diagnosis before something fails dangerously.
Insulation & Earth Fault Testing
Calibrated AS/NZS 3017 testing of insulation resistance and earth fault loop impedance — the technical work that finds hidden faults.

Frequently Asked Questions
- How much does electrical fault finding cost in Hervey Bay?
- Fixed diagnosis fee $185-$245 (credited toward repair if you proceed). Repair quote provided separately so you can decide whether to fix or get a second opinion. No open-ended bills.
- Why does my safety switch keep tripping in Hervey Bay?
- Most common: an appliance with degraded insulation (often older fridges, washing machines or pool pumps), or moisture in an outdoor circuit after rain/storm. Sometimes the RCD itself is failing. Diagnosis confirms which.
- Can you find intermittent faults?
- Yes — these are our specialty. We use data loggers (recording over hours or days), thermal imaging to find hot connections, and systematic isolation methods. Most intermittent faults that 'no one else could find' are findable with the right approach.
- Is fault finding covered by home insurance?
- Sometimes — particularly if the fault has caused damage (e.g. a fire, smoke, or appliance failure caused by an electrical fault). Speak to your insurer; we provide itemised invoicing that supports claims.
