The DuckBill Grounding Clamp provides secure connections in grounding and jumper assemblies for utility and industrial electrical systems. Its snap-on close mechanism enables quick installation, reducing setup time during field operations while ensuring reliable performance across diverse environments.<\/p>\n

The clamp features an aluminum body for corrosion resistance and typically includes a bronze eyescrew for enhanced durability and mechanical strength. These materials provide excellent electrical conductivity and longevity in grounding applications. Models accommodate jaw openings from 0.162 to 1.66 inches, with smooth or serrated edges to suit different conductor types. The threaded ferrule uses 5\/8-11 Unified National Coarse (UNC) threads and supports cable sizes from #2 American Wire Gauge (AWG) to 4\/0.<\/p>\n

Electrically, the clamp maintains a continuous current rating of 400 amperes and handles maximum fault currents of 43 kA for 15 cycles or 30 kA for 30 cycles. It accommodates main conductors from #6 solid copper to 1113 kcmil Aluminum Conductor Steel Reinforced (ACSR), maintaining low resistance and stable performance under fault conditions.<\/p>\n

Installation requires 250 in-lb torque for the eyescrew and ferrule to ensure connection integrity. The design includes a lubrication chamber for thread maintenance and stress relief features to minimize cable damage. The clamp complies with American Society for Testing and Materials (ASTM) F855 standards and meets Grade 5 or 5H fault current testing requirements.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>
