Is Rubber Wiring Dangerous? Old Cables Explained
Rubber wiring has not been used in the UK since approximately the mid-1950s. Other countries may have used rubber wiring for a longer or shorter period than this.
Whilst rubber wiring was ok when installed many decades ago, it was never intended to last until now and any black rubber cables that are still in use today are likely to be dangerous. As the rubber has aged it has become brittle and the slightest movement is likely to cause the rubber to fracture and fall away. This will leave bare metal wiring exposed, live to the touch, cables shorting out and a high risk of electrical fires.
