Device Box
A Device Box, also known as an electrical box or junction box, is a container installed in walls, ceilings, or floors where electrical connections are made. It's a fundamental component in electrical installations that provides a safe and secure space for housing electrical outlets, switches, and wire connections. Think of it as a protective housing that keeps electrical components organized and safely contained, much like a small safe for electrical connections. Electricians work with these boxes daily as they're required by building codes for most electrical installations in homes and commercial buildings.
