An electrical junction board (or box) is a protective enclosure where multiple electrical wires connect, serving as a vital hub for distributing power, organizing circuits, and ensuring safety by housing splices and preventing shocks or fires from exposed connections in homes, industries, and commercial setups. These robust boxes, made of metal or plastic, safely contain wiring, making systems accessible for repairs, additions, and managing different circuits (like power, neutral, ground) for various appliances and fixtures, from lights to heavy machinery.

Connection Point: Gathers and joins multiple wires from different parts of a building’s electrical system.

Protection: Shields live wires and connections from dust, moisture, physical damage, and accidental contact, reducing shock and fire hazards.

Organization: Keeps wiring tidy, accessible, and manageable, making troubleshooting and modifications easier.

Power Distribution: Acts as a central point to split power from one source to several loads (lights, outlets, appliances).

Materials: Commonly made from plastic (PVC, SMC) or metal (galvanized iron, steel) for durability and weather resistance.

Types: Available in various sizes (e.g., 2×3 inches, 4×3 inches) and forms, including flush-mounted, surface-mounted, or specialized industrial/solar boxes

Found in walls, ceilings, and industrial settings to connect light fixtures, switches, outlets, and larger machinery.

Essential for safety compliance with electrical codes (like ANSI/IEC standards).
