Solar Grounding Lug AL6005-T5 & Stainless Steel SUS304 - Rail Terminal Clamp for Copper Grounding Cable

F CFA 500 F CFA 1 000

Heavy-duty solar grounding lug made of AL6005-T5 aluminum and SUS304 stainless steel. Mounts directly onto aluminum rails to secure the main copper earth wire, providing safe electrical discharge to the ground system.

Complete the grounding protection of your solar array with this high-conductivity Solar Grounding Lug (Earthing Terminal Clamp).

Designed to attach directly to the aluminum mounting rail channel, this grounding lug securely holds the main bare or insulated copper grounding cable, safely directing static electricity, stray currents, and surge energy into the ground rod network.

Key Features:

  • High-Strength Materials: Anodized high-conductivity AL6005-T5 aluminum alloy body paired with SUS304 stainless steel clamping bolts.

  • Easy Wire Clamping: Side-entry jaw with an Allen bolt allows fast, firm clamping of standard copper grounding cables.

  • Corrosion Resistant: Built for long-term outdoor exposure, resisting UV degradation, high humidity, and rust.

  • Quick Rail Insertion: Comes pre-assembled with a T-nut sliding channel bolt for effortless locking inside standard aluminum rail grooves.

It acts as the physical connection point between the aluminum mounting rail structure and the main copper earth wire, safely grounding the entire solar array.

Typically, 1 grounding lug per rail line or row is installed to tie each mounting section into the continuous earth ground system.

The clamping jaw accommodates standard grounding copper cable sizes ranging from 4 mm² up to 16 mm² (8 to 6 AWG)
