Electrical Fault Finding & Testing in Kings Hill

Electrical fault-finding calls from Kings Hill properties follow a different pattern to older housing areas. The development's newer-build properties have original circuit installations from the late 1990s and 2000s — less susceptible to the insulation resistance degradation that drives fault calls in older Kent terrace stock, but presenting different fault sources related to the age of the original RCD devices and, increasingly, informal modifications made during the development's history.

The most common fault-finding calls from Kings Hill residential properties involve: nuisance tripping from RCD devices that are now approaching 25–30 years of age and have degraded operational characteristics; intermittent faults from informally installed garden or outbuilding circuits where cable damage has occurred; and, in some properties, fault conditions arising from solar PV or EV charger installations that were not correctly incorporated into the consumer unit.

For commercial premises at Kings Hill Business Park, fault-finding calls sometimes involve sub-distribution board issues in larger office buildings — where circuit arrangements have been modified over the years by different occupiers.
