The Flat Face Ground Clamp establishes electrical connections between equipment and ground using a flat jaw design that maximizes surface contact. Constructed from aluminum or bronze for conductivity and corrosion resistance, these clamps feature serrated jaws that enhance grip and secure attachment. Fine-thread eye screws or T-handles enable easy adjustment and operation.
Standard jaw openings range from 0.125 to 2 inches, with weights between 1.48 and 2.666 pounds. Performance specifications include continuous current ratings of 300 to 400 amperes and fault current ratings from 20,000 amperes for 30 cycles up to 47,000 amperes for short durations. Grounding wire capacity accommodates #2 to 4/0 cable, depending on terminal type.
Common applications include utility work, maintenance, and construction, where the clamps connect to grounding rods, angle iron, and bus bars. They accommodate copper and aluminum conductors, with material compatibility preventing galvanic corrosion for long-term reliability.
Installation requires cleaning the conductor surface, positioning the clamp, and tightening using the eye screw or T-handle mechanism with torque values ranging from 20 foot-pounds to 250 inch-pounds. These clamps comply with American Society for Testing and Materials (ASTM) grades including Grade 3 and Grade 5 standards.
