Cabling conditions in Randburg

Randburg's established suburbs were mostly built between the 1960s and 1980s, so much of the wiring in its houses, garden flats and older complexes is reaching the end of its life. Electricians regularly find undersized cable, old rewireable fuse boards and illegal extensions when doing COC inspections for sales. Retail strips along Bram Fischer Drive and light industrial pockets in Strijdom Park and Ferndale need three-phase supplies, signage circuits and shop refits. Cable theft and vandalism affect parts of the network, and many homes added inverters and batteries during load-shedding. Rocky ground around Northcliff and Linden can make trenching for garden and outbuilding supplies harder.
