Cabling conditions in Centurion

Centurion is a fast-growing area of security estates, townhouse complexes and office parks along the N1 and N14, where builders and developers order cable in bulk for new phases. Much of the area sits on dolomite, so geotechnical rules can influence where and how deep underground cable and services may be laid, and water leaks near trenches are taken seriously. Homeowners on estates were quick to add inverters and batteries during load-shedding, which led to plenty of solar, battery and DB board work. Office parks and data facilities near the highways need structured cabling and backup power. Summer lightning storms remain a regular risk.
