How the two Northriding reports fit together
City Power initially attributed the Tourmaline trip to cable theft. An earlier Randburg notice named Randpark Ridge, Northwold, Sundowner and Boskruin without identifying the equipment or cause. The restoration notice for Tourmaline named Northwold and Sundowner.
The 11 November notice concerned an earth fault on the same Tourmaline distributor. The available notices do not establish that the cable fault caused the later earth fault. The restoration notice applies to the earlier incident.
