Intermittent electrical faults are often the hardest to diagnose — especially when nothing looks obviously wrong.
We were recently called out to a property where the breaker was intermittently tripping. The initial concern was that one of the heaters may have been causing the issue.
After testing all heaters and finding no immediate faults, we began tracing the circuit and looking at other likely causes — particularly anything exposed to potential moisture.
On further inspection, we came across a socket in a lower-level bedroom where external ground levels were higher than the internal wall. Although nothing was immediately obvious from the front, closer inspection showed signs of corrosion.
Once removed, the issue became clear — significant moisture ingress had caused internal corrosion and contamination on the conductors.
Faults like this can be difficult to diagnose. They often start as intermittent trips and gradually worsen over time as the damage increases.
To make the installation safe, we removed the socket, terminated the conductors securely within an enclosure, and advised on the underlying issue that would need to be resolved before reinstating the outlet.
Another good example of why electrical faults aren’t always where you expect them — and why proper investigation matters.
