Peter,
May be mistaken, but I don't think "Tape" is mentioned specifically anywhere in
the code. What kind of splices do you have in mind? Not wirenuts I hope? One of
my pet peeves, sorry.
I don't have my 2008 Codebook handy. 2005 NEC Article 110.14(B) requires, "All
splices and joints and the fr
At this point, there are much better products for splicing than split bolts.
The insulated splice blocks don't need tape, and are easy to check later too.
I just don't see a reason to use uninsulated splices anymore. All your time
spent wrapping (and unwrapping) will more than pay the difference
Hello Larry,
Are there any materials that will react problematically with
butyl? Do you fill pilot holes with anything. I typically use
silicon. I haven't used this combination before.
Thanks,
Drake

I agree. However, be aware that most commonly available insulated connectors are
not listed for motor applications (think vibration). I recently had to resort to
the tried and true, taped, split bolt splice

Can anyone give me the NEC reference for taping UL-listed wire

Anything else that pertains?
If a splice needs to be insulated, "linerless splicing tape" is a
good option. Wrap some Scotch 33 a
Correcting my previous post:
I use the newer insulated connectors 95% of the time, for the reasons you
mention, but not because they provide a lower resistance splice. My sense is
that a properly executed split bolt splice
is equivalent, or superior, resistance-wise, to any other splice or termin
Interesting training videos on the 3M website covering recommended practices
in taping splices.

Wrenches,
With the Iceland volcano in the news and winter over, I thought it would be
a good time ask wrenches convince their customers that their reduced solar
production was caused by atmospheric conditions and not their PV system. I'm
not talking about short-term conditions like a few cloud
Joel:
I have noticed that the energy predicted by the CSI calculator is
consistently lower than the first year output of our systems, usually by at
least
10% to 20%. This is also true of the PVWatts version we use.
At first we thought that we had done such a great job! But I believe that
hello Wrenches,
Many years ago I had the (unfortunate?) experience of working for a couple of
roofing companies. I was much more nimble back then. It did however, teach me
some good (and bad) methods of working on and and with roofing materials. Some
tips:
- Roof jacks are very easy to install
Pat,
Kicked your butts as far as lower output? If so, by how much on a
percentage basis?
On the Big Island of Hawaii, we've had a very active volcano doing its thing
since 1983. With the normal trade winds, the vog (volcanic smoke + fog)
gets blown south past the volcano, around the south
Marco:
Our production schedule has been in tatters - lowered by perhaps 30%
because of the rain can't plan, can't do. Then I pay overtime on good

to (try to) catch up.
We have a number of systems online and I had not thought to actually
review and compare from this year to last.
This thread brings up a very timely issue that I’m dealing with right now with
