<p>Disclosed is a bushing well adapted for use with a bushing insert having an end portion including a first threaded electrical contact element. The well is made of dielectric material which is shaped to define a receptacle for receiving the end portion of the insert, the well being provided with a second threaded electrical contact element which is integrally secured to the well. A threaded coupling member (60, 80) made of electrically conductive material is provided for connecting the first contact element (14) to the second contact element (44) when the insert (10) is received in the well (42). The coupling member (60, 80) has wrenching means (74, 92) to enable a portion of the coupling member (60, 80) to be removed from the second contact element (14) in the event of a fracture which separates the portion from the remainder of the coupling member (60, 80).</p> |
