Arild,
Thanks you for you response. The type of crimp tool I used in the past was
a
box type with a rotating die from 6 AWG to 1/0 AWG. When I bought this
crimpier I said wow this will be the last one.
I am not familiar with the single die and round nosed crimpier. Is it easy
to figure out the proper crimp size for your mismatch lugs and wires? I
guess one should do some practice crimps.
Also how do you suggest that I cut the cable? I have an Ancor wire cutter
rated to 2/0. Which I don't think will "cut" it.
Thanks

Quoting Duane Maher duane@maher.name:
My question is where do I find the proper size lugs? I will
need to reterminate some of these cable runs. Do I go the next size up
or next
size down and try to make it fit. This makes me a little
uncomfortable.
Any
help would be appreciated.

Much depends on whattype crimp tool you will be using.
A "Box" type crimper ( Burndy and T&B style) which creates a square box
shaped
impression into the round lug requires more closely matched wires and
crimps.
Ancor sells a crimp tool which has an adjustable die and a single round
nosed
pin impression. This is my preference since it does allow yo uto adjust
for a
mismatch of lugs and wires.
Another solution is to add extra strands to fil the space inside the
crimp
barrel befoer crimping down.
Since a pull test is not practical on this size cable connection you
have
to
rely on past experience and judgement.
Having done two previous boats I suspect you do havethe requisite
experience to
judge if your crimp is sound.
Trying to stuff a cable into a too small crimp barrel is more
problematic.
I would not recommend that approach.

Duane,
I solved this problem by going to a hardware store that sells lawn and
garden supplys and bought a pruning type cutter made to cut small tree
limbs, maybe up to about 1 1/2" in diameter. It's made like a giant pair of
side cutters with curved jaws. I actually originally bought this cutter to
cut dock lines in an emergency but when I was installing my inverter I
needed to cut 4/0 cables and it worked great. Makes a very clean cut with
little effort. I.m sure cutting a large amount of cables will dull the
edges, but making a few cuts on these cables (15 or 20 or so) hasn't seemed
to hurt them, and they are still at the ready to cut a dock line if I get
into trouble.

They'll work fine. You'll just have to squeeze a lot harder. :)
