Electrical Cable Colour Codes for Cape Town homes and businesses

Many homes and businesses in Cape Town have a mix of older red and black wiring and newer brown and blue cable, especially after extensions and repairs. Registered electricians working across Western Cape can test, trace and correct the wiring, label the DB board and issue a Certificate of Compliance for a sale or insurance.

Cabling conditions in Cape Town

Salt air is the main enemy of cable in Cape Town. Along the Atlantic Seaboard and False Bay, exposed glands, lugs and outdoor DB boards corrode quickly, so stainless or brass fittings and sealed enclosures are worth the extra cost. Most suburbs buy power from the City rather than Eskom, and rooftop solar has spread fast, with the City requiring registration and approval before a grid-tied system is connected. Old Victorian and Bo-Kaap homes often still carry rubber-insulated or red-and-black wiring that needs replacing. Wet winters flood poorly sealed conduit runs, and cable theft remains a persistent problem along rail lines and streetlight circuits.
