Adjustable ground clamp

An adjustable clamping device for mechanical and electrical connection to the sides of a conductor which may have a variety of different widths, comprising:

• a base spanning the conductor and having a pair of arms extending from the ends of the base and positionable adjacent the sides of the conductor;
• one of the arms including a threaded opening and a threaded bolt moveable therein for engagement with its adjacent side of the conductor, the threaded bolt having an abrading surface for abrading the side of the conductor to penetrate the outer surface thereof, the threaded bolt further including a head portion having formed therein a bore for receiving an electrical conductor, a second threaded opening, and a securing screw for securing the electrical conductor within the base to the head portion;
• and
• adjustment means for varying the length of the base within a predetermined range of lengths whereby the clamping device is adjustable for different width conductors.

An adjustable ground clamp for mechanical and electrical connection to the sides of a conductor which is to be grounded, comprising:

• a first elongated base member terminating in an end portion extending at an angle generally less than or equal to 90.degree. from the first elongated base member;
• a second elongated base member overlapping said first base member and terminating in an end portion extending at an angle generally less than or equal to 90.degree. from the second elongated base member;
• adjustment means for interconnecting the overlapped elongated base members at different positions to adjust the distance between the end portions to each be positioned closely adjacent a side of the conductor;
• and
• ground means mounted on one of the end portions and moveable into engagement with its adjacent side of the conductor for abrading the adjacent side surface to form an intimate electrical ground connection therewith.
