excellent. They truly are basically "irreversible" in that you need to cut the wires to remove the splice in any reasonable manner.

If these are equivalent to the T&B part, they are rated for solid or stranded wire. Take a look at page B43 of

We use these Panduit C-taps:

They work great and the compression tool is relatively inexpensive but there is question about whether they're listed for use with solid wire.

What economical splice hardware are people using when you don't have two end of a ground wires to land in the Buchanan Splice Caps? Split bolts are mighty expensive....

Subject: [RE-wrenches] Splice Caps
We have been using Buchanan brand "splice caps" to splice two to three #10
Cu EGCs inside 3R-rated j-boxes. Is there an approved methodology for
splicing ECGs under PV modules (i.e. exposed to the elements). I understand
that otherwise listed lay-in lugs are not acceptable for double lugging. -

Peter,
(1) it appears that per the WEEB installation manual:
<a class="moz-txt-link-freetext" href="http://www.we-llc.com/Datasheets/104-0404-000008-008.pdf" target="_blank">http://www.we-llc.com/Datasheets/104-0404-000008-008.pdf</a>
(page 8) you need to have one WEEB per module rather than one for every
other module as you suggest.
(2) 690.43 Equipment Grounding.
Exposed non-current-carrying metal parts of module frames, equipment,
and conductor enclosures shall be grounded in accordance with 250.134 or
250.136(A) regardless of voltage.
I guess the latter answer depends on whether your AHJ considers the
rails "exposed"-- I would, so in this situation I'd have lugs on each
module and each rail.

<pre>We have been using WEEB clips on all of our installations for over a
year now. We include the WEEB data/installation sheets in our permit
package and patiently point out the clips to inspectors who haven't seen
the WEEB system yet.
Two questions:
(1) For ProSolar rails, can we use one WEEB clip to bond two
adjacent modules (say, modules A and B) on the upper rail (say, rail #1)
and then use a second WEEB clip to bond the next two adjacent modules
(say, modules C and D) on the lower rail (say, rail #2) and then use a
listed lay-in lug (with in our case a WEEB clip) to bond to either rail
#1 or #2 to continue the grounding?
(2) If we DON"T use WEEB clips and use the conventional bonding
methodology per module manufacturer's instructions (proper location on
the module, and listed screws, washers and nuts), do we have to ALSO
bond the rails? We have an inspector in Pasadena, CA that is requiring
this, but this is the first time we have been required to do so. Perhaps
in the past year in ignorant bliss we have missed an important
development? Or have we been dodging bullets for seven years and not
even knowing it?
