a faulted array removing modules without disabling them is likely to be injured
whether or not there is a lug or a clip. The circuit must be disabled before
taking loose anything. Not an easy task, but necessary. The argument that we
need ground wires on everything because technicians are less likely to be hurt
with a faulted array misses the point. The array frames need to be grounded so
the fault current will flow to activate the ground fault protection. Once it
has done its job, it is up to the technician to think the process through and
not kill themselves.<o:p></o:p></span></p>

<br>
2 points:<br>
<br>
1) For the sake of clarity: there are WEEB <a
href="http://www.we-llc.com/Datasheets/204-0404-000003.pdf">LUGS</a> and WEEB <a
href="http://www.we-llc.com/Datasheets/204-0404-000007.pdf">CLIPS</a>.
WEEB Lugs are comprised of very robust tin-plated copper lugs, stainless steel
hardware, and the actual WEEB, which is the stainless steel nippled
"washer" that pierces aluminum anodization. WEEB Clips are
simply stainless steal nippled washers that are installed between module and
rail that form a bond, theoretically eliminating the need to bond the module to
a ground wire, so long as the rails are properly grounded.<br>
<br>
2) My biggest concern with the WEEB Clip is that the moment a top-clamp is
loosened the module is no longer grounded!!! To me that is not a good
grounding method. Mr Wiley is obviously a talented inventor and he makes
a strong argument for the quality of the bond that the WEEB Clip provides when
the clip is installed properly and all mounting hardware is properly
torqued. What I don't understand is the argument that this is as safe of
a product as a properly installed outdoor rated lug for the service tech who
has to work on that array. <br>
<br>
<br>
A tin-plated copper lug with a stainless steel set screw will last. A
service tech working on a faulted array that was grounded with WEEB Clips might
not.<br>

Are you sure that's a ILSCO GBL-4DBT lug? I am pretty sure the set screw is<br>
not SS, which it should be to be the genuine part.<br>
