WHY IS FAULTY WIRING DANGEROUS
Deteriorated electrical wiring is dangerous, and can cause house fires.
Old wires and cables were insulated with rubber, which tends to degrade and crumble away over time. Exposed wires can cause regular electrical faults and fires.
Modern wires are insulated with PVC, which is durable and has low conductivity. Modern PVC cables are usually white or grey, not black like old rubber cables.
If any of the following applies to your home, you’ll need to get your wiring inspected and updated right away.
