Has anyone seen new boats that use individual terminal blocks mounted on a DIN
rail instead of the conventional barrier terminal strips?

I have recently come across a product that seems so neat and effective that I
am wondering why more boat builders are not looking at using them also.

The advantage of these terminal blocks are;
you do not need crimp on terminals,
the actual assembly goes faster,
they can accommodate many more wires in a given space, and
the blocks better accommodate joining wires of different sizes than a butt
splice
greater flexibility in wiring not mention joining several wires to a common
point.
Making changes is easier than with conventional terminal strips
the wire fastening system is gas tight and vibration proof.

Arild

We use these blocks at work. I did look into using them on my boat,
but found the larger size I wanted (to take #10 wire) was a bit too
expensive for my liking. I think I was looking for a two-level block
that could be bridged on both levels, so one block would handle both
positive and negative leads for one circuit - perhaps single-level
blocks would be cheaper (but not quite so neat for wiring...)

My custom Seaton trawler uses them, Arild. Perhaps they are not as
cost-effective on production boats as they are on one-off projects.

Just a hunch.

For those who may not be familiar with the DIN rail terminal blocks
that Arild mentioned, I've put a couple of pictures of them on

And I really like the Panduit cableway that is used to organize cable
runs in these photos. Unlike bundling with cable ties you can easily
add and remove cables. It is great stuff for organizing cable runs,
both on land in the network closet and aboard boats. Take a look at
http://www.panduiteeg.com/product_category/RO_wiring_duct.asp for
product info on wiring ducts.

REPLY
When cables are tightly bundled you have to derate them for amperage due to
heat build-up.
When they are loosely bundled inside a wire duct like Pan-duit, the heat
buildup is reduced.

Conduit or wire loom used on boats must be self draining to prevent
collecting moisture in the low spots. Panduit meets that requirement.
Unlike pipe conduit it is easier to add extra wires and break out one pair
anywhere along the run.
Panduit come in 6 foot lengths. I used to order it in bulk so we always had
several lengths on hand for panel building.
It comes in sizes ranging from 3/4" wide to about 4" as well as various
depths. I have seen black white and gray.

Production builders like Carver have been using it for years but I wish they
would pick a larger size.
They tend to cram the ducts so full there is no room for adding accessories
supplied after the sale.
Perhaps in the mistaken belief that saving a few pennies up front still offsets
the increased labor costs later.

Cheers
