Tin-plated copper lay-in lugs are the best choice for grounding solar panels. They allow the use of one continuous grounding conductor, as per code requirements, or as a jumper to multiple locations. No need to thread the connector. Just back off the set screw, “lay in” the wire, and re-tighten. It’s also easy to retrofit or repair. These is our premium copper lug, UL/CSA rated for indoor, outdoor, and direct-burial applications. This is an electro-tin plated copper lug to assure minimum contact resistance and protection against corrosion when used with copper wire, with a stainless steel set screw, for a durable and reliable connection all year around. Includes a stainless #10-32 x 5/8″ screw with kept-nut (with a serrated washer), providing a complete solution for bolting the lug to a solar panel or racking. Features Fits 14 AWG – 4 AWG conductors Acceptable for direct burial in earth or concrete, indoor, and outdoor use Stainless steel hardware for corrosion resistance, greater torque and ease of installation Made from high strength copper alloy Electra tin-plated, RoHS compliant Provides low contact resistance Suitable for use with copper or aluminum conductors for grounding & continuous loop application Lay-in feature UL 467 & CSA listed
