Wiley Electronics is the creator of the well known bonding washers WEEB. WEEB stands for "washer, electrical equipment bonding". WEEB products are used to bond solar modules to aluminum racking and mounting rails. The solar modules and the racking system are then grounded, grounding and interconnecting the entire assembly into one single grounding system. The use of WEEBs eliminates the need to use a lay-in lug and/or a thread-forming screw on each module. The use of WEEBs also eliminates the need to run a continuous wire to each module. Wire is only needed to connect a lay-in lug on each mounting rail to an equipment grounding terminal in the inverter or disconnect.
It has been continuously proven that WEEBs save installers time and money. WEEB products are ETL listed to UL standards. WEEB products meet the requirements of UL 467.
WEEB-11.5 grounding clips are used between modules and DPW PowerTube CRS Rail Brackets.
The WEEB-11.5 is a splice plate grounding clip commonly used with DPW mounting hardware. It is a washer used to create an electric bond between the brackets used to secure the solar panels and the Power Beam Rails from DPW. You must use at least one WEEB-11.5 with every mounting bracket including the joiner bracket. Using more than one grounding clip in rail joints is recommended. The WEEB washer or clip is placed on the T-bolt and under the bracket.
It is also used with other equipment brands to create a bond between mounting rails and other points of attachment like trays, pole and ground mounts. It allows for 3/8” hardware.
We advise speaking to your building inspector before installing WEEB products to see if they are acceptable in your area.
