Answer
Old rubber wiring, commonly used until the mid-1950s, can become hazardous over time. As rubber ages, it becomes brittle, leading to cracks and exposure of live wires. This deterioration increases the risk of electric shocks, short circuits, and electrical fires. If your home still contains rubber-insulated wiring, it's crucial to have it inspected and replaced by a qualified electrician to ensure safety.
If your home still has rubber wiring in place from the 1950s it is highly recommended that you have your home professionally rewired.
