Fault Finding by Local Licensed Electricians

Electrical faults can appear in countless forms—tripping circuits, blown fuses, dead power points, flickering lights, rain or rodent damage to wiring, accidental garden cable cuts, and more. That’s why expert Melbourne electrical fault finding homeowners trust is so important. At Thomas Group Electrical, we bring the latest diagnostic technology—thermal imaging to spot hidden hot spots, insulation testers for checking conductor integrity, and precision multimeters for voltage and current measurements—to every job.

Our process starts with a comprehensive visual inspection of switchboards and wiring runs, followed by systematic testing of each circuit. Once the problem area is identified, we isolate and repair only the faulty components, preserving the rest of your system and saving you time and money in unnecessary replacements.

Don’t Risk DIY Fault Finding

It might seem easy to swap out a flickering outlet or reset a tripped breaker yourself, but DIY electrical work carries serious risks. Hidden faults—like loose neutral connections, damaged insulation, or overloaded circuits—can turn a minor nuisance into an electrical fire or shock hazard. Unlicensed repairs also void many home insurance policies and can incur fines up to $40,000 or even jail time.

Our fully licensed electricians perform a battery of safety checks—continuity tests, earth-leakage measurements, insulation-resistance readings, and final functional verifications—all in strict accordance with Australian Wiring Rules (AS/NZS 3000). This rigorous approach ensures that every repair not only fixes the immediate fault but also maintains your entire system’s safety and compliance.

We can recalibrate charging algorithms or swap out faulty circuit boards. For networked setups, we restore communication links so billing, monitoring, and RFID access work smoothly again.

Hear What Our Happy Clients Say About Us…

Just had some electrical work/ security camera set up done by Ethan, and I honestly couldn’t be happier. He was super efficient, really patient, and just overall great to work with. You can tell he knows his stuff and actually cares about doing a good job. What really stood out was the customer service — so friendly and easy to talk to. He took the time to explain what he was doing and made sure I was comfortable with everything. No rush, no pressure, just really solid work.

P.S  my dogs loved him

Anna - Kilsyth

Ethan fitted me into his schedule at short notice after we had an electrical fault emergency. Ethan was very knowledgeable and future safety was top of his list. He identified the issue immediately and fixed the damage it had caused and tested my appliance which put my mind at ease after quite a frightening experience. 5 stars, my go to electrician from now on

Debbie - Croydon

Had a great experience with Thomas Group Electrical. They were punctual, professional, and easy to deal with from the moment they arrived. They replaced a few outlets and carried out a full check of all the smoke alarms and sockets. The work was done efficiently, to a high standard, and they left everything neat and tidy. It’s reassuring to have tradespeople who are both reliable and respectful. I’d happily recommend them to anyone needing quality electrical work.

Angus - Mornington

Fast, friendly, and zero fuss. Ethan spotted an overloaded circuit I’d been ignoring for years and fixed it on the spot. Plus the bonus surge protector gives real peace of mind—no more worrying about storms frying my gear!

Melissa - Cheltenham

Ethan was incredibly thorough with our safety inspection—every circuit, outlet, and switch was checked from top to bottom. He installed the surge protection device in under an hour, and our home hasn’t tripped once since. Highly recommend Ethan’s service!

Case Study: Domestic Fault Finding

 A family in Kilsyth lost power to their guest wing late one Friday afternoon. We dispatched an A-Grade electrician that same day. Using clamp meters and isolation techniques, the fault was traced to a garden fountain pump drawing excessive current and tripping the safety switch. 

After sourcing and installing a new, weatherproof pump, the circuit was retested under full load, and power was safely restored—all before the weekend began. The customer appreciated our thorough approach and same-day resolution, avoiding the cost and hassle of a repeat call-out.
