<div class="moz-cite-prefix">Hi Glenn;<br>
<br>
Quick Cable that provides the UL listed cables and lugs, also
sells this tool for those lugs. I don't know about UL testing,
etc. Is the inspector actually asking to see the tool? The
Greenlee tool that makes the same type crimp is definitely good
stuff. However, there is no substitute for good craftsmanship.
A lot of equipment with UL listings is junk, so UL by itself is no
guarantee of quality or safety. I think we can all dig around
our household for more examples of inferior products sporting the
UL emblem. (Consider those 39 cent AC receptacles that break
plastic off around the ground opening, the first time you plug
something into them, or later, allow plugs to fall half out of the
receptacle, because they've lost their "spring".)<br>
Like any tool, the hammer crimper can be misused. The biggest
problem I've seen is folks not stripping enough insulation off the
cable, and so not enough copper goes past the crimp into the lug.
These failed the "pull" test. We once had to redo a whole battery
bank of crimps because the previous installer had not stripped
enough insulation off. See below:<br>

THHN Stiff Class B wire, and Corrosion don't help either. Believe
it or not, that lug cleaned up nicely once soaked in baking soda
water for 1/2 hr.<br>

<p class="MsoNormal">Here's all the battery lug crimpers I
tried over the years in order of the best to worst
connections they produced:<br>
<bdbagfhj.jpg><br>
Yes, believe it or not: the venerable Hammer crimper
makes excellent connections. Its also Cheap, but its
Slow, cumbersome, and can't be used in a J box.<br>
The V and indent connection with the thin wall lugs
makes the ideal battery and DC connections. They look
just like the crimps from Outback, Trace, Midnite,etc.
I've cut them open on a band saw, and the fine strands
are practically fused together into an almost solid
cross section of copper with no voids, but no tearing of
strands at the edges either.<br>
This crimper goes out on most jobs, as it fits in the
bottom of the tool box.<br>
<fhibhicd.jpg><br>
The Greenlee indentor crimper makes the same V crimp
connection as the hammer crimper, but is faster, and can
be used up in a j box. More expensive, and adjuster
readings can't be counted on. I tighten the adjuster
until I can just pull the handle down with putting some
body weight into it, but not so much that I'm standing
on it or straining the tool. Depending on the cable and
lug combination, the setting may be 2 sizes smaller with
thin wall lugs.<br>
Overall, this is what we use most of the time. I found
that this set in a drill vice makes a good bench
crimper, when you need to do a batch of battery jumpers.<br>
<br>
<fcafcjdi.jpg><br>
I used this one for many years, also a V crimper, but
has different dies. Crimp quality was not as good, as
the dies tore into the lug some. Also changing the dies
took time, and we once lost one of the dies, and it took
months to get a replacement. Not adjustable for
different lug and cable combos.<br>
<br>
<bfdddceg.jpg><br>
The "UL" Hex type crimper that you will find at regular
electrical supply houses. Quite expensive, but I am not
a fan. The dies bend slightly under pressure and so the
hex crimps are not aligned with each other. The dies
tear the lugs, leaving sharp edges that can tear heat
shrink, and there is no adjustment available to account
for different cable and lug combinations. <br>
We have X flex from Cobra, MTW from Quick Cable, and
some DLO from another supplier. All are UL listed 4/0
and all somewhat different in diam. and how the strands
crush. I have had a connection failure with this tool,
and cutting through a cross section of the lug was not
as solid a crimp as the V type. I removed this tool
from our shop, to avoid mistakes.<br>
I'm sure with regular Class B stranded THHN, and the
heavy wall, color coded lugs, that this is a good tool,
but for battery connections, it does not work as well
with thin wall lugs.<br>
Finally, I do not recommend the heavy wall, long barrel
lugs on batteries. The square lug end is just too big
and thick, and can't bolt to battery terminals in some
cases. We have had to grind away a corner for instance
to have the heavy wall lugs land on an battery Flag
terminal. <br>
The heavy terminals some what negate the advantages of
flex cable in the first place.<br>
