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?
