Should junction boxes be considered terminals or connections
A junction box is a general-purpose enclosure used to safely contain wire splices—connections where electrical wires are joined together. Fundamental Distinction: Terminal boxes utilize structured terminal blocks for organized, accessible connections and frequent maintenance, whereas junction boxes protect permanent wire splices and are rarely accessed after installation. While both serve as protective enclosures for electrical wiring, their primary functions and internal configurations differ significantly, catering to distinct needs within an electrical system. They are trying to decide which enclosure makes more sense for a real installation: a simple power branch, an outdoor lighting circuit, a field device connection point, or a structured. A terminal box offers neat, secure wire terminations in fixed layouts, while a junction box is flexible and easy to expand for splices and general wiring.
