What Is the Difference Between Explosion-Proof Junction Boxes and Explosion-Proof Threading Boxes

To assist in selecting the right explosion-proof electrical devices, today we’re highlighting the differences between explosion-proof junction boxes and explosion-proof conduit boxes. Although both are key components in explosion-proof electrical systems, they differ significantly in function and characteristics, despite their similar names.

Explosion-Proof Junction Boxes:

Starting with explosion-proof junction boxes, these devices serve as connection points between power distribution, electrical equipment, and external wiring. They play a crucial role in line protection, housing terminal strips or connection terminals with switchgear. Typically, these devices are designed to be detachable for ease of maintenance and configuration.

Explosion-Proof Conduit Boxes:

Moving on to explosion-proof conduit boxes, these are used when the length of a conduit exceeds certain limits, or when there are deviations or excessive bends in the wiring path. In such cases, adding a conduit box at strategic points facilitates easier wire threading and management. These boxes bridge the gap in complex wiring layouts.

Both the junction and conduit boxes are made from non-copper aluminum alloy castings with a corrosion-resistant, powder-coated surface. They meet the necessary explosion-proof standards, ensuring safety in hazardous environments.
