Abstract: A clamp is provided which automatically latches onto a power line when brought into contact with the line for grounding the line or other purposes. The clamp has structural features which prevent inadvertent triggering of the latch mechanism before contact with the power line.

Abstract: A clamp is provided for grounding electrical power lines and the like. The clamp automatically latches itself into a firm gripping relationship with the electrical power line when brought into contact with the power line.

Abstract: An apparatus is provided for grounding power distribution cable so that maintenance can be perfomed on power distribution equipment or the cable. The apparatus has multiple wells, at least two of which are adapted to receive any of several types of conductor bushing inserts to match the cable elbows, while a third receives a load break bushing which is adapted to receive a grounding elbow.

Abstract: A new and improved apparatus is provided to permit a live or hot electrical power line to be cut in the field for line service or other purposes. The apparatus is connected at each end to the line at positions spanning the site of the cut. The attached end portions are then moved closer to each other, easing the tension on the portion of the line to be cut. The apparatus is then connected to the live line with jumper cables, forming a parallel electric circuit. The line is then cut and a cut end tied back. Flow of current through the apparatus is broken. An interrupter in the apparatus suppresses any arc which may tend to form.
