A householder's protective device trips three times in a fortnight, always in the evening, never while anybody is watching.
An electrician attends, finds nothing tripping, tests everything available and leaves. It trips again four days later during heavy rain.
Nothing was done badly. An intermittent fault that does not present during a visit cannot be found during that visit, and nobody had gathered the information that would have pointed at the outdoor circuit.
The first failure: nobody records when it happens
Time of day, what was being used, what the weather was doing. This log is the single most useful diagnostic tool and it costs nothing to keep.
The second failure: the customer does not know they can help
Most people assume fault finding is entirely the electrician's job. Telling somebody to note the circumstances turns four visits into one.
The third failure: the appliance possibility is not tested first
A faulty appliance is the commonest cause and it is identified by unplugging things systematically, which a householder can do before anybody attends.
The fourth failure: the weather connection is missed
Outdoor circuits, external lights, garden supplies and anything where moisture can enter. A fault that tracks the weather points somewhere specific.
The fifth failure: cumulative leakage is not understood
Several appliances each contributing a small amount can trip a device without any of them being faulty, which produces a fault that appears when a particular combination is used.
The sixth failure: nothing is explained about how the device works
Customers do not know what a protective device is detecting, which means a trip feels arbitrary rather than informative.
The seventh failure: the chargeable nature is not stated
Fault finding takes time with no guaranteed outcome. Customers expect a fixed price and a fix, and the honest position has to be set before the visit.
The eighth failure: the urgent cases are not separated
Burning smells, scorch marks, heat at a socket or a shock are not fault finding enquiries, and they need an immediate response, which is the ground in electrical faults that need a safety first reply.
The ninth failure: the customer resets repeatedly
Repeatedly resetting a device that keeps tripping is treating a warning as a nuisance, and it should be explained rather than assumed to be understood.
The tenth failure: the recent work connection is not asked about
A fault that began after a kitchen was fitted, a floor was nailed down or an appliance was installed has an obvious first place to look.
The eleventh failure: the visit is scheduled at the wrong time
If it only trips in the evening, an appointment at ten in the morning is unlikely to be useful, and the scheduling is rarely considered.
The twelfth failure: the partial finding is not communicated
Where a visit eliminates several possibilities without finding the fault, that is genuine progress, and a customer told nothing concludes the visit achieved nothing.
The fix: gather the pattern before anybody attends
An assistant that asks when it trips, what was being used, whether weather is involved, what was done recently and whether anything unsafe is present narrows an intermittent fault before a visit and separates the urgent cases immediately.
