Cabling conditions in Johannesburg

Johannesburg has a huge stock of older homes in suburbs like Melville, Parkhurst and Kensington, where original rubber- or VIR-insulated wiring, overloaded circuits and missing earth leakage protection make rewiring and COC inspections common jobs. Much of the city is supplied by City Power, while some areas are fed directly by Eskom. Cable theft and vandalism regularly cause outages, so businesses and complexes often ask about protected routes and backup supply. Inner-city building conversions need new risers and distribution boards, and the rocky quartzite ridges can make trenching slow. Highveld lightning is frequent in summer, so surge protection is worth including in most quotes.
