Look here on the right side of the page where the fitting looks like the one used above.
http://www.bptfittings.com/main.html I also reviewed the contractor's corner, and it was helpful.
Bottom line, although the "weep hole" has been used for the GEC in many installations, is that the hole is not really designed for that use!
The bonding of the enclosure to the GEC is required by the code, and cannot be accomplished without the use of a properly designed fitting. I would leave a RED TAG on a service if I found that the "weep hole" was uused for the GEC.
The best way to settle this issue is to submit a proposal to CMP 5 and I would be willing to bet, that the comment rejecting it would be similiar to my comment above.
