🔍 These cables supplied a property for decades. A closer look shows why their condition matters.
These meter tails came from a single-phase 40 A supply in Malta. Under the microscope, the individual metal strands show deep indentations, flattened sections, sharp bends and some apparently cut or broken strands.
There are no apparent signs of arcing in this case. However, the overall condition of the terminations appears unsuitable for continued use.
⚠️ Why does a poor connection matter?
It can cause localised overheating, damage the insulation, create an intermittent supply and, if it deteriorates further, lead to arcing or fire. A poor connection can overheat even below 40 A, without drawing enough current to blow the fuse or trip the circuit breaker.
“It has worked for years” is no guarantee that it remains safe today.
Having electrical installations inspected periodically by a qualified professional can help identify deterioration before it becomes a serious problem.
