Cabling conditions in Pretoria

Pretoria's electricity is mostly supplied by the City of Tshwane, with some outlying areas on Eskom, so connection upgrades and meter changes start with the right utility. Older face-brick homes in Brooklyn, Waterkloof and Lynnwood often need rewiring, larger supply cables and new DB boards when owners add air-conditioning, heat pumps or solar. Government departments, embassies, hospitals and universities generate institutional cabling and network work. The east of the city keeps expanding with new estates and complexes. Rocky ridges and hard ground in many suburbs affect trenching, and frequent summer lightning makes earthing and surge protection a sensible part of any installation here.
