A preassembled cathodic protection system is provided for protecting buried structures such as guy anchors, which includes a reference cell, test station and anode, all prewired together and tested before delivery and field installation. The package includes a convenient connection for the structure which has one lead to an exposed stud or contact point on the test station, and another lead from the connection to the anode or anodes through a shunt in the form of a calibrated resistance wire. The shunt is connected to two spaced studs or contact points on the test station by which the shunt is read. The reference cell is also connected to a stud or contact point on the test station. The reference cell-test station lead extends through a flexible tube. The studs or contact points are on the dome or cap of a rigid tube designed to project out of the ground or an electrolyte a short distance. With a guy anchor the tube may include an elow and angled portion. The interior of the dome or cap is totally encapsulated in epoxy or other potting or sealing compound, which encapsulation includes all of the test station connections as well as the shunt.
