Ang mga junction box na patunay ng pagsabog ay ikinategorya batay sa laki ng kanilang mga entry sa daluyan, mula sa 1/2 pulgada sa 3 pulgada. Kabilang dito ang mga sukat tulad ng 1/2 pulgada, 3/4 pulgada, 1 pulgada, 1.2 pulgada, 1.5 pulgada, 2 pulgada, 2.5 pulgada, at 3 pulgada. Dagdag pa rito, 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 ko na: 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 pasabog na mga kapaligiran, ensuring safety and reliability in hazardous industrial settings.
