Interference B2 Pedestal

Interference between pipelines or structures can be very damaging to both objects. Interference may be caused when a competing cathodic protection system crosses the path of your main cathodic protection system. Mitigating this problem is critical but doesn’t have to be expensive. Corrpro’s Interference B2 Pedestal junction box can provide an adjustable amount of current between the structures. Equipped standard with a 1 Ohm – 300w slide resistor, you can change the amount of current going between the two structures and minimizing the interference generated. The current is measured on a standard 10A – 50mV shunt.

While interference mitigation is the main purpose for the IF B2 pedestal, it can also be used to apply a small amount of current on a secondary structure. With the slide resistor installed, you can select the amount of current required to protect the secondary circuit
