The WEEB-9.5 is used for bonding modules to mounting structures when the modules are directly bolted to the rails using 1/4" bolts through the mounting holes on the rear of the module frames. This type of mounting is typical on DP&W ground and pole mount systems and on Wattsun and Zomeworks trackers. The WEEB-9.5NL is used for bonding strong-back structure and legs to the rail where 3/8" bolts are used.
Sold in packs of 10.
WEEB stands for "washer, electrical equipment bonding." WEEB products are used to bond solar modules to aluminum solar mounting rails. The mounts are then grounded, grounding the entire assembly. This eliminates the need to use a lay-in lug and thread-forming screw on each module and it eliminates the need to run a continuous wire to each module.
This saves time and money and it meets the requirements of UL 467. Wire is only needed to connect a lay-in lug on each module rail to an equipment grounding terminal in the inverter or disconnect. ETL listed to UL standards.
