Actually, if you were following the thread, Norm said
"However, I also use two 100 amp, 3 phase, ac circuit
breakers on DC" followed by a comment that he's been
using hardware store circuit breakers for a long time.
This is a jury rig in my book - think the
characteristics of these breakers operating on a dc
circuit are what was intended? While I disagree with a
lot of Norm's inventive solutions to problems, I also
recognize that Norm is a bit handier than the average
boat owner and seems to weight the pros and cons and
decides what risks he is willing to live with. OK.

Lot of discussion when it appears we agree on basics.
As I've said. I don't lend a lot of credence to ABYC
except in the areas that a surveyor might write up.
ABYC is a commercial venture and as such should not be
used as standards anyway.
I never said you need to buy only ABYC approved parts
- is there really such a list?
As far as marine parts, a good rule of thumb is to
stick to marine or industrial type products, stay away
from the home depot wire nuts type stuff. I would feel
perfectly comfortable defending any part on my boat
even though I don't look for ABYC approved devices -
as you say they just paid to get on the list. There
are a lot of reputable parts makers who make parts for
industry and marine application who have not submitted
for ABYC approval. How many parts are actually on an
ABYC aprovaed list, anyway? Who cares?
Most part do not need ABYC 'approval'. My box of T&B
terminal lugs, anybodies terminal strips, tape,
connection boxes, plumbing fittings, etc all are in my
parts bin and none came with 'ABYC approval'. Ditto
for light fixtures, switches, and a lot of other stuff
on my boat - but it is all robust, proper equipment
designed for the purpose to which it is put.

I believe my comment, as pertaining to shuttle parts,
was if you have to ask you probably shouldn't use it.
In this case it helps if you at least know the
different types of CB available. There is a big
difference between someone with industry knowledge
substituting parts and the average boater plugging in
the wrong part. It's something I'm very careful about
when out of my area of expertise.

Funny, I actually checked the specs of some 'diesel
locomotive' wire compared to marine and it wasn't the
same, and it wasn't just tinning. I personally prefer
Belden cable.

Actually on this paticular part you'd be looking for
the UL listed stamp.

I doubt it.
Sign me,
