What electrical fault finding actually involves

Fault finding is a process of elimination, not guesswork. Circuits are isolated and tested one at a time, insulation resistance is measured, and loads are separated to find whether the problem is a faulty appliance, damaged cabling or an overloaded circuit. That method is what stops a recurring trip from turning into a monthly call-out.

Because Annlin sits within our core Pretoria footprint, routine visits here do not carry long-distance travel charges. We confirm parking, access control and after-hours arrangements before attending.
