[RE-wrenches] Array Grounding Clips

[ASAP POWER! 2]

Jeff, excellent questions.  Also, how many clips per say, 100 or 1000 ft of
clipped-on ground wire are recommended?  Is the distance in between clips
per code or certification of the clip in any way?   Does anyone have a cost
per linear foot comparison between lug+bare+labor and sliced bread?

There was a period when the news on the module to frame grouding clips said
these were the best thing since sliced bread, then I thought I heard there
was some long-term bonding concerns and UL or NEC may re-visit.  
[PD:] has been re-visited?

The two main brands are the UniRac in-house grounding clips and the Wiley
Electronics WEEB grounding clips. There may be others.   The WEEB model line
appreas to have more models and options, while the UniRac has a much lower
cost.

Is the industry going this direction and away from bare copper?  Are these
approved and OK to use now?   Which brands do you like?

Are most of you still using a lay-in rear ground lug and bare copper ground
wire, or have you found a better way to ground modules that still meets
code?

Thansk,
