ABSTRACT OF THE DISCLOSURE Electrical currents and potentials in test leads associated with underground piping, cables and the like are monitored by a test station apparatus which essen- tially includes a collar supported by a tubular plastic conduit for subterranean implantation or carried above- ground by a carrier plate. A plastic tube projecting from diametrically-opposed sides of the conduit provides one form of anchor means to maintain the conduit within the ground while in another form the anchor means consists of a collar retained on the lower end of the conduit by a sleeve. Further embodiments include two different forms of carrier plates for aboveground support of the test station. A collet-type compression fitting is used to attach a collar onto the upper end of the conduit. Pedestals extend vertically from the end wall at opposed sides of an annular opening in the collar. The pedestals support a terminal block extending across the annular opening so that test leads pass through the collar for attachment at either side of the terminal block to ter- minals which are normally enclosed by a dome-shaped cover secured to the collar by threads or by one of different embodiments of interlocking members.
