When the cabling deteriorates it can result in “cable greening,” where a dark green substance seeps out of electrical switches and sockets.
It can often go unnoticed until electrical maintenance is underway. In more extreme situations, you might even observe it trickling down the wall below electrical fixtures.
While the plasticiser itself lacks conductivity, the visible green goo comprises plasticiser and copper oxide making it conductive and posing the risk of electric shock.
The warmer the cable becomes, the more plasticiser leaches out, leading to potential brittleness and the eventual breakdown of the cable. This deterioration can result in insulation or short circuit faults, leading to tripping of circuit breakers or RCDs.
Contact with the green substance may cause adverse effects such as dermatitis or rashes. Therefore, precautions should be taken to avoid skin contact.
