TEST STATION APPARATUS FOR FLUSH MOUNTING

摘要

TEST STATION APPARATUS FOR FLUSH MOUNTING Electrical currents and potentials in test leads associated with underground piping, cables and the like are monitored through the use of a cathodic test station for flush mounting in the ground. The test station includes a hollow cylindrical housing having a flanged upper end and an implanted lower end receiving test leads and anchored in the ground by a bar extending therethrough and by ribs projecting radially from the outer surface of the housing. A carrier forms an airtight pocket within side walls projecting from a solid end wall having a flange extending outwardly for recessed support on a shelf in the flanged upper end of the housing. A clip within the airtight pocket of the carrier extends across the face of the end wall with ends of the clip spaced from the end wall to support a mounting wall of a terminal block member. The mounting wall has a configuration to pass beyond the ends of the clip so that rotation of the terminal block member moves an inclined support surface into a tightly fitting engagement between the end wall and the clip. Entrapped air in the airtight pocket of the carrier prevents ingress of water. A fastener releasably secures the carrier to the housing.
