How Explosion-Proof Junction Boxes Differ from Threading Boxes

Explosion-proof conduit boxes, primarily designed for threading and branching wires, are essential in contexts where electrical wire lengths are significant. For instance, when connecting three galvanized pipes, a BHC-G3/4-B three-way explosion-proof conduit box is necessary.

In contrast, explosion-proof junction boxes house terminal blocks to secure and distribute electrical lines. Unlike conduit boxes, which are typically empty, junction boxes are equipped with functional components.

The conduit boxes fall under the Exe increased safety type, while junction boxes are categorized as Exd flameproof type. Despite both being 6-section specifications, they differ in weight and structural design.
