Ground clamp

A ground clamp comprising:

• (a) an electrically-conductive main member;
• (b) a lower upper flange projecting outward from the main member;
• (c) an electrically-conductive upper flange projecting outward from the main member such that the upper flange is above the lower flange, and such that the upper flange is conductively connected to the main member;
• (d) one or more lugs or abutments projecting upward from the lower flange;
• and
• (e) an electrically-conductive bolt having a bolt stem, wherein:
• the bolt is rotatably engageable within a threaded hole or nut associated with the upper flange, such the bolt is conductively connected to the upper flange and thereby to the main member;
• the lower end of the bolt stem is oriented toward the lower flange;
• and
• the lower end of the bolt stem has a downward-oriented concave recess having a sharp-edged circumferential rim;
• such that when a conductive element of a structure or equipment unit requiring grounding is disposed between the lugs and the lower end of the bolt stem, rotation of the bolt will cause the conductive element to become clamped between the lugs and the bolt stem, with the bolt stem's sharp-edged circumferential rim rotatingly penetrating the surface of the conductive element to establish electrically-conductive connection therewith, and thereby establishing electrically-conductive connection between the conductive element and the main member.
