The Lay In Lug Grounding Connector is a high-quality copper wire connector designed specifically for secure and reliable grounding applications. This product is ideal for use with solid and stranded AWG copper wires, making it suitable for various electrical and grounding setups, including swimming pool grounding where reliability and durability are critical. The connector features an open-faced design that allows installers to quickly lay in the grounding conductor as a jumper to multiple conduits without breaking the ground conductor. Made from ETP grade copper and finished with a copper flash, these connectors ensure excellent conductivity and corrosion resistance. The screws are made from low carbon steel with a zinc plating and blue passivation layer for added protection. UL certified for safety and performance, these lay in lugs come in multiple wire size ranges, accommodating from #14 to #250 copper wires. They carry a “DB” marking which certifies them for direct burial, an essential feature for outdoor grounding installations. The product undergoes rigorous testing to guarantee secure connections under torque and pullout stresses without any cracking, distortion, or thread damage, thereby ensuring long-lasting mechanical and electrical integrity.
