[RE-wrenches] The Demise of melodrama in this thread

[Kirk Herander, VSE]

"The technician dies"? - one would hope a person would have the sense to
wear safety gear, per OSHA and NFPA standards,  when debugging a ground
fault.

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.
