Re: [RE-wrenches] Pass through/transition box for Enphase

[Glenn Burt]

The Ideal website for the Buchanan splice has a link to the UL listing for the 
product. It does not list it for use with anything other than standard stranded 
conductors.
If it is not part of the listing, it is not approved for that use, regardless 
of historical or anecdotal use.
That is what the NEC says, and what the UL listing says and the UL 
specification for their listing says.

Jeremy,



Without digging into the specs on the Ideal connectors, I doubt that they
will work with fine-stranded wire.



The problem with these types of connectors is that the set screw that you
turn to tighten the connection is in direct contact with the wire strands.
As you tighten it, it rubs the strands in a circular motion, which will
stretch, flatten, and tear the strands. It would work fine if you use
ferrules, but not without them.



Terminals that are rated for direct use with fine-stranded wire would have
a clamping-type terminal, where the screw used to tighten the connection
pushes down on a solid piece of metal which then clamps the wire. Even in
this case, it may still not be approved for fine-stranded wire depending on
its design.



The Buchanan splices should be fine. They are basically the same as a
ferrule, except that they are crimped with a crimping tool instead of the
pressure from tightening a screw in a bus bar. The crimping tool is not in
direct contact with the wire strands, so there is no tearing or other
damage to the wire. However, the spec sheet does not specify the acceptable
wire types, and I can’t seem to find anything with a Google search. It
might be worth contacting Buchanan/Ideal to see if they have better info.

Re: [RE-wrenches] Pass through/transition box for Enphase

[August Goers]

Hopefully manufacturers will steer away from supplying fine stranded wires
with their trunk cables – it’s been a joke trying to fine the proper listed
reasonably priced parts to make these connections. I bet that a huge
percentage of the installs out there are not meeting the listing for fine
stranded conductors.



That said, we use ferrules on the individual fine stranded conductors and
then make the splices with the Ideal/Buchanan splice caps. This particular
combo was presented in the SunPower ACPV instruction document and says it
is listed for their class K conductors. I haven’t looked up the listing
documents myself (at least recently) since this was presented in the
manufacturer’s manual. As I posted before, the Ideal splice caps are the
bomb! We love them and I’d highly recommend checking them out if you
haven’t already.



Best,



August

So this may be a dumb question, but I'm assuming wire nuts are not 
suitable for Fine strand wire?  I agree that most installs are not code 
compliant in this regard.  Its really tough to find parts or even good

Re: [RE-wrenches] Pass through/transition box for Enphase

[Nick Soleil]

Hi Wrenches,


Enphase was manufacturing Engage Cable with fine strand (Type K) wiring.  Due 
to the challenges with wire terminals that are being discussed, we switched our 
manufacturing lines to standard, 19 strand conductors.


The transition to 19 strand Engage Cable occurred in late 2015, and the stock 
of fine strand cable should be largely flushed out of distribution channels at 
this time.  Our manufacturing and distribution channels are set up to so that 
the product that comes in first goes out first, so hopefully you don't have to 
deal with this issue again.



Cordially,

Nick Soleil

Re: [RE-wrenches] Off grid

[Daniel Tittmann]

Just had a client with a 20 + yr old top loader tripping the 30 amp input
breaker on a magnum 2012 even when running a 10 K generator.  Lock rotor
current on these old beasts can be a real issue, and it got worse over
time.

Re: [RE-wrenches] Pass through/transition box for Enphase

[Glenn Burt]

No dumb questions.
I however cannot speak authoritatively on the twist-on splices as I haven't 
done any research on them. I suspect after the research I have done, that they 
do not have a listing for finely stranded conductors either, but that may be 
for someone else to confirm.

So this may be a dumb question, but I'm assuming wire nuts are not 
suitable for Fine strand wire?  I agree that most installs are not code 
compliant in this regard.  Its really tough to find parts or even good

Re: [RE-wrenches] Standing seam metal roof attachments for copper roof

[Shasta Daiku]

Daniel,

My own home has a lot of Corten steel elements, roof, soffits, eaves and some 
doors. Most everything in contact with the Corten is stainless steel, including 
fasteners, plumbing vents, and chimney pipe flashing. The one thing that is not 
SS are the gable end flashings which are copper. Last year I pulled one off 
because I had not gotten a definitive answer as to the compatibility of Corten 
and copper and was curious. I found evidence of mild electrolysis on the Corten 
surface where the two materials made contact. I ended up separating the two 
surfaces with SS.

Re: [RE-wrenches] Pass through/transition box for Enphase

[Jerry Shafer]

We will not alow any of our people or any subs to use wire nut twist nuts,
over the years l have seen way to many electrical issues as a result in
someone using the twist nuts, approved crimps are the best way to go with
the least space required.

Re: [RE-wrenches] Pass through/transition box for Enphase

[Glenn Burt]

Interesting product, and good for standard stranding conductors, as their UL
486C certification attests.

They are however a screw to conductor connection device and will have the
same limitation when used with finely stranded conductors as the standard
Polaris splices.

The Polaris grey connectors have a metal sleeve already in the port as part
of the device, which the screw crushes against the fine stranded conductors
- essentially performing the same function as installing ferrules on the
conductors.

When we have the Enphase 240 VAC trunk line branching in two directions we
use these 300V rated Alumiconn 3 port connectors, to make them up to the #10
THWN-2. These are a scaled down version of the Polaris insultaps.
