Preventing Electric Shock from Home Electrical Distribution Boxes
Use and regularly test your GFCI outlets and plugs. GFCI is short for “Ground Fault Circuit Interrupters. ” GFCIs will prevent an electrical shock hazard by cutting off power when there has been a fault interruption in the electrical current. Ricardo Mitchell is the CEO of CN Coterie, a fully licensed and insured Lead EPA (Environmental Protection Agency) Certified construction company located in Manhattan, New York. Frayed or damaged cords are an accident waiting to happen. When the protective insulation wears down, the electrical current is exposed, increasing the risk of electric shock. Electrical shock occurs when a person comes into contact with an electrical current. The severity of the shock depends on several factors, including the voltage, the person's health, and the path the current takes through the body.
