Cabling conditions in KwaZulu-Natal

KwaZulu-Natal's humid coast is tough on exposed copper, terminals and steel accessories, so installers along the Durban coastline and the north and south coasts choose sealed enclosures, stainless or coated fittings and properly glanded armoured cable. Inland, the Midlands and northern areas get frequent summer thunderstorms, and lightning protection is a regular topic on farms and in rural homes. The ports at Durban and Richards Bay, heavy industry and sugar mills create demand for larger power cable and cable tray. Coastal estates and apartment blocks bring complex wiring work, while flooding in recent years has shown the value of well-routed, protected underground supplies.

Complexes and body corporates: body corporates have unit wiring checked and labelled when COCs are needed for sales
