What Is Fault Finding and When Do You Need It?

Fault finding, in plain terms

Fault finding is the process of working out why something electrical has gone wrong when the cause isn't obvious. That might be a safety switch that keeps tripping, a circuit that's gone completely dead, or lights that flicker for no clear reason. In newer homes with well-documented wiring, this can be quick. In older houses around Yarraville, Seddon and Footscray, where wiring has often been added to and altered over decades without anyone keeping a record, it takes more digging.

What it actually involves

An electrician doing fault finding will usually:

• Ask what's happening and when, including if it's weather-related, tied to a particular appliance, or constant.

• Check the switchboard first, since a lot of faults show up there before anyone touches a wall or ceiling.

• Test individual circuits to isolate where the fault is coming from.

• Check likely culprits, outdoor points, old wiring joins, appliances, before opening anything up.

• Explain what was found and what it means, including whether it's a quick fix or points to a bigger issue.

A real example

One Yarraville home had a safety switch that tripped every time it rained, for months, before anyone found the cause. It turned out to be an outdoor power point that had been letting water in. Nobody else had worked it out. That's a good example of what fault finding actually looks like: not guesswork, but methodically ruling things out until the actual cause is found.

When you need it

• A safety switch trips repeatedly, especially in a pattern (after rain, when an appliance runs, at a certain time of day)

• A circuit has stopped working and resetting the switchboard doesn't fix it

• Lights flicker, dim, or buzz without an obvious cause

• You smell burning or notice a power point or switch feels warm

That last one shouldn't wait. The others are worth getting looked at reasonably soon, especially if they're becoming more frequent.

Getting it diagnosed

Fault finding in older homes is rarely a flat fee, since nobody knows how long it will take until the cause is found. Smaller jobs like this are generally charged by the hour plus parts, and you'll be told the rate before work starts. If opening something up reveals a bigger problem, like wiring that needs replacing, you'll be shown what's been found and given a price for that before anyone carries on.
