Cabling conditions in Western Cape

In the Western Cape, cable work has to suit both a salty coastline and a busy winter rainfall season. Outdoor runs, distribution boards and glands near the sea need corrosion-resistant fittings, while wet winters expose poor joints and water ingress in older installations. Cape Town's municipal grid helped shield some customers from the worst load-shedding, but rooftop solar has still grown strongly across homes, wine farms and businesses, creating steady demand for PV and battery cable. Farms in the Boland and along the West Coast need long underground feeds to pumps, cellars and staff housing, and building activity in the city and coastal towns keeps wholesalers busy.

Typical electrical cable colour codes requests in the area come from:

Homeowners: older homes often mix red and black wiring with newer brown and blue cable after extensions
Solar and backup power: solar installers keep AC colours consistent and clearly label DC positive and negative separately
Farms and smallholdings: older farm wiring often uses inconsistent colours that need tracing before upgrades
Coastal properties: coastal homes may have faded or corroded insulation that makes core colours hard to read
Complexes and body corporates: body corporates have unit wiring checked and labelled when COCs are needed for sales
Shops and retail: shops with three-phase supplies need phases identified and balanced across the DB board
