There is nothing more frustrating than coming home to find the power out for no apparent reason, or having the breaker trip randomly once a week. These are “ghost faults” and are usually due to:

  1. Moisture in outdoor circuits: A drop of water in a garden light can be enough.
  2. Appliances with intermittent leaks: Sometimes, a fridge compressor only fails when it kicks in.
  3. External grid interference: Harmonics from the public grid that “trick” your RCD/breaker.

Locating these faults is like looking for a needle in a haystack for someone without experience. Our technicians use high-precision leakage clamps that track the problem down to the exact device, saving you hours of frustration and unnecessary resets.
