Outlet boxes are electrical enclosures that house electrical outlets, providing a safe and secure way to connect electrical devices to a power source. They are typically made of plastic or metal and are installed within walls, ceilings, or floors. Outlet boxes help protect wiring and prevent accidental contact with live electrical components. These boxes come in various sizes and types, including standard outlet boxes for regular outlets and specialty outlet boxes for specific applications like outdoor use or low-voltage wiring. Proper installation of outlet boxes is essential for electrical safety and compliance with local building codes.
