An old cable inevitably accompanies an old burning box, which is not ideal for modern living conditions. The pressure on an older scheme makes this much less safe than a modern fusebox thanks to an increasing quantity of home appliances and electronics.
The quick fix is to create a fresh fusebox that is far more delicate than an older model and tears off quickly enough to avoid electrocution before something severe occurs. The new fusebox will shut down a circuit. If you think your home electrics need attention, please contact.
