## Overview
Electrical faults rarely announce themselves. A safety switch that trips every time it rains, an oven that works until the kettle boils, a bedroom that lost half its outlets after a storm — every one of these is a specific fault waiting to be isolated. We chase them systematically using a megger, clamp meter, earth loop tester and thermal camera, not by swapping parts until something works.
Most Sydney fault-finding calls fall into a handful of patterns: moisture ingress into an outdoor outlet or bathroom fan; a failing appliance (usually a hot water element, dishwasher or oven) putting an earth leak on the circuit; a damaged cable behind plaster after a picture hook or shelf install; or a corroded neutral in an old junction box in the roof. We walk the circuit, isolate the fault to a specific section, then quote the fix in writing before continuing.
You leave the visit knowing exactly what was wrong, why it happened, and what it takes to stop it recurring — with photos, meter readings and a compliance certificate for any repair work done.

## Fixed pricing
$220–$850 AUD per fault. Workmanship warranty 12 months. Typical on-site duration ~1.5 hours.

## Symptoms we hear about
- Circuit trips repeatedly
- Half the house has no power
- Burning smell with no visible cause
- Lights flicker under load

## Common causes
- Failed appliance drawing to earth
- Damaged cable behind plasterboard
- Loose neutral in the switchboard
- Water-ingressed outdoor GPO

## How we handle it
1. **Isolate the fault** — We split the affected circuit and reset breakers one by one to narrow the fault to a single run.
2. **Insulation resistance test** — Megger the suspect circuit to confirm whether the fault is line-to-earth, line-to-neutral, or intermittent.
3. **Trace and repair** — Thermal camera and cable tracer locate the fault, we replace the damaged section and re-test.
4. **Certify** — Full test to AS/NZS 3000 and a CCEW covering the repair.

## Applicable standards
- AS/NZS 3000:2018 Section 8 — Verification
- AS/NZS 3017 — Verification testing

## Recent anonymised jobs
### Tripping RCD isolated to an outdoor GPO
A safety switch in Strathfield kept tripping whenever it rained. We isolated the fault to water ingress in an outdoor power point, replaced it with a weatherproof IP-rated unit and resealed the cable entry. Jobs like this between Strathfield Square and Strathfield Station are part of our regular Strathfield run, so callouts here rarely wait long. It's a pattern we see across Strathfield: large stock of Federation-era homes with original wiring — ceramic fuseboards and unshielded VIR cabling are still common finds.
Outcome: Weatherproof GPO installed, RCD no longer trips in wet weather.. Approx. 110 minutes on site.

### Buzzing switchboard traced to a failing breaker
An audible buzzing from the switchboard in Strathfield was reported before it got worse. We found a breaker with a degraded internal contact, replaced it and thermal-imaged the board to rule out other hot spots. Most of the housing on this side of Strathfield is Federation homes, so we planned cable routes and fixing points around that before touching a tool.
Outcome: Faulty breaker replaced, board confirmed fault-free.. Approx. 130 minutes on site.

## FAQs
**Why does my safety switch keep tripping?**
Almost always moisture ingress, a failing appliance (hot water, oven, dishwasher) or a damaged cable. We meter every circuit to find the leaking one, then isolate it to a section — usually inside 60-90 minutes.

**How much does electrical fault finding cost?**
Standard diagnostic callout is $99, waived if you proceed with the repair. Most single-circuit faults are isolated and quoted inside 60-90 minutes. Complex multi-circuit or buried cable faults are quoted hourly once we've scoped the work.

**Can you find a fault without ripping walls apart?**
In the vast majority of cases yes. Between insulation resistance testing, cable tracing tools and a thermal camera we can isolate a fault to a specific outlet, junction or short cable section without opening walls unnecessarily.

**Do you attend after hours for urgent faults?**
Yes — 24/7 emergency callouts across Sydney. If you have sparks, exposed wiring or burning smells, turn power off at the main and call us immediately.

**Will you fix the fault the same visit?**
Most faults are repaired the same visit if the parts are on the van (RCBOs, outlets, cable, common appliance parts). Complex repairs (buried cable replacement, board rewire) are scheduled after the quote is approved.

**Do you provide a written fault report?**
Yes — photos of the fault, meter readings, root-cause explanation and a written repair quote. Useful for insurance claims and landlord records.

**Can a DIY-installed appliance cause a nuisance trip?**
Very common. DIY-installed dishwashers, hot water elements, downlights and outdoor lights are a top cause of RCD tripping. We often find the fault on the appliance rather than the wiring — cheaper to know than to guess.
