Junction Box for Cathodic Protection
BSS Technologies manufactures custom junction boxes designed for safe current distribution, electrical bonding, and continuous monitoring across complex Cathodic Protection networks.
Cathodic Protection Junction Box
Junction boxes form a critical connection and control point within any cathodic protection setup. They are utilized to safely route, control, and distribute electrical current from transformer rectifiers to multiple anode groundbeds or protected metallic structures.

At BSS Technologies, we custom manufacture the junction box units to fit your precise project requirements and technical specifications. Because we offer complete flexibility, we can supply everything from simple bonding enclosures to highly complex distribution nodes equipped with monitoring hardware.

Types of CP Junction Boxes
Junction Box Type | Primary Function | Typical Site Applications |
|---|---|---|
Anode Junction Box | Distributes positive DC current to multiple anodes. | ICCP groundbeds, deep wells, and tank bottoms. |
Negative Junction Box | Consolidates return cables from protected structures. | Cross-country pipelines and marine platforms. |
Bonding Junction Box | Provides controlled electrical bonding or isolation. | Mitigating interference across parallel pipelines. |
Monitoring Junction Box | Measures current and controls circuit resistance. | Sacrificial anode arrays and complex ICCP setups. |
Use the guide above to specify the appropriate junction box type based on your system architecture.
