Construction site electrical distribution box overheats
Overloading leads to overheating of circuit components and may cause a fire. Do not use power strips or surge protectors rated for home use on a construction site. Use GFCI-protected power cords rated for construction use that meet OSHA stan-dards for attaching to power tools. Electrocution is the third greatest fatality cause on construction sites because it can instantly kill, cause serious burns, or cause unconscious-ness. Once an electrical hazard is identified, it is the responsibility of the employer to have it corrected by a qualified electrician or competent. Electrical boxes—whether found in basements, attics, or walls—are designed to safely manage your home's electricity. Homeowners often overlook common risks like loose connections, overloaded circuits, and poor ventilation. Overheating inside a panel is not just about a breaker panel hot to the touch.
