The SOLKLAMP grounding bolt from TE Connectivity shortens the installation time required to ground modules in a solar array. The threaded bolt, secured with a supplied one-piece lock washer-nut, inserts through the ground hole of a solar module aluminum frame and penetrates its surface to establish a reliable ground path. The SOLKLAMP grounding bolt handles 6 to 12 AWG (13.3 and 3.3 mm2) solid, uninsulated copper wire. The six-second, short-term current test indicates that the product handles 1530 Amps with 6 AWG ground wire. In the UL 486A/B pull-out test, the grounding bolt provides 100 pounds (45.3 kg) retention with 6 AWG wire. The product meets the requirements of UL 1703 for safety in flat-plate photovoltaic modules and panels, as well as the UL 467 requirements for grounding and bonding equipment.
