Abstract
Abstract A two pair station protector is used at a station to protect pairs of telephone circuit lines from high voltage or surge currents and includes a base assembly having an upstanding wall with a pair of notches, in each of which is insertable an insulating grommet and through each of which is extendable said lines. The base assembly also includes an overvoltage arrester mounting section for overvoltage arresters, a line terminal section containing four line terminals and a ground terminal coupled to the arresters and a storage space between the upstanding wall and line terminal section. In order to facilitate the wiring of the telephone lines extending through the grommets to the line terminals and to associate the line terminals with the arresters to which it is coupled, the line terminals are disposed between the upstanding wall and the arrester mounting section such that two of the line terminals are in alignment with one of the notches and the other two of the line terminals are aligned with the other notch. In the preferred embodiment, a cover is slidably mounted over the base assembly to protect the base assembly from the weather, insects and tampering and the station protector has two in line mounting holes and an offset mounting hole to facilitate mounting of the station protector to a mounting surface.
