Wear and Tear
The outer sheath of an electrical cord is designed to be tough to protect the more delicate insulation of the inner cores. The flexibility of the sheath diminishes over time and becomes brittle, leading to cracking as can be seen here. The inner insulation is then exposed to damage, with the copper conductors becoming exposed enabling a user to come into contact with it.
