Andrew:
You make a very good point in 2) below, however there is one step
missing: If a ground fault is occurring, the technician will eventually
need to look under modules to find the fault. This is the reason the
top-down clips will be loosened. If the module is grounded with #6 wire,
the wire will prevent the module from being lifted. Therefore, the lug
will also be loosened, un-grounding the module -- creating the unsafe
condition you described.
WEEB clip or WEEB lug, the technician dies.
Should we invent a WEEB jumper cable to maintain module bond while the
modules are being lifted?

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.
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.
