Explosion-proof junction boxes are categorized based on the size of their conduit entries, ranging from 1/2 inch to 3 inches. This includes sizes like 1/2 inch, 3/4 inch, 1 inch, 1.2 inches, 1.5 inches, 2 inches, 2.5 inches, and 3 inches. Furthermore, these junction boxes come in ten distinct design specifications, each suited to different installation requirements:
1. Type A: Straight Run Flat – Ideal for linear conduit connections.
2. Type B: Direct Pass Flat – Designed for straight-through cable routing.
3. Type C: T-Pass Flat – Suitable for T-shaped conduit intersections.
4. Type D: Cross Pass Flat – Used for cross-shaped conduit junctions.
5. Type E: Elbow Pass Flat – Perfect for right-angle bends in conduits.
6. Type F: Straight Run Hanging – Optimized for vertical linear connections.
7. Type G: Direct Pass Hanging – Facilitates straight-through cable routing in suspended installations.
8. Type H: T-Pass Hanging – Ideal for T-shaped intersections in overhead conduits.
9. Type I: Cross Pass Hanging – Designed for cross junctions in suspended conduit systems.
10. Type J: Elbow Pass Hanging – Best for right-angle turns in hanging conduits.
Each of these types is crafted to provide seamless and secure connections in various explosive environments, ensuring safety and reliability in hazardous industrial settings.
