Diagnostic Investigation Protocol

How electrical fault finding works in Exeter

A methodical, non-destructive isolation procedure that tracks down faults without tearing apart your property.

We analyze which breaker trips, when the failure occurs, and which appliances or environmental factors trigger the condition.

Thermal imaging cameras and digital multimeters scan your consumer unit for hotspot degradation and voltage fluctuations.

Individual conductors undergo high-voltage megohmmeter testing to uncover pinched cables, moisture ingress, or rodent chewing.

The damaged cable segment, outlet, or component is repaired, retested under full electrical load, and confirmed safe.

Electrical Fault Finding & Diagnostics FAQs

Answers property owners in Exeter, Devon usually want before requesting electrical fault finding & diagnostics quotes.

Why does my RCD or circuit breaker keep tripping, and why shouldn't I keep resetting it?

An RCD (Residual Current Device) or circuit breaker trips for three primary reasons: an electrical overload (too many appliances drawing power simultaneously), a dead short circuit (a hot wire contacting a neutral or ground wire), or an earth fault leakage (current leaking to ground due to damaged insulation, moisture ingress, or a faulty appliance heating element). You should never repeatedly force a breaker back on: doing so forces high fault currents through compromised wiring, rapidly accelerating heat buildup and risking an electrical fire. Our diagnostic electricians isolate circuits one by one using calibrated testers to find the exact failure point.
