When it comes to electrical fires, faulty wiring is often to blame. Over time, exposure to heat, moisture, and vibrations can cause the insulation around electrical wires to deteriorate, exposing the bare wires. This can create a fire hazard, as the wires may come into contact with other combustible materials or short circuit. In addition, faulty wiring may also be caused by improper installation or damaged cords. Improper installation can occur when amateurs attempt to wire an electrical system without following the proper code requirements. This often leads to overloaded circuits and loose connections, which can create a fire hazard. Finally, damaged cords can also lead to faulty wiring. Common causes of cord damage include pests chewing through the insulation, exposure to excessive heat, or being pinched or crushed. If not repaired or replaced, damaged cords can eventually lead to a fire.
