About this item
The XR-LUG is the low-profile grounding lug for XR rails. Drop it into the rail T-slot, run your equipment grounding conductor through it, torque. It connects the array's bonded rails to your EGC at a single point per row (or per the layout your inspector signs off on).
Most installs run a single 10 AWG copper EGC through the XR-LUG and out to the inverter or combiner ground bus. The lug accepts solid or stranded copper.
Even though the UFO mid clamps and BOSS splices already bond rails and modules into the IronRidge Integrated Grounding system, you still need at least one external lug per array to land the EGC. That's what this part does.
UL 2703 listed as part of the XR system. 25-year IronRidge warranty.
