I am about to install 4 T-105s, for a house bank, and the best, shortest
route to the inveter for the cables, is down the outside of the battery
box for the +ve, and under the battery box, to the inverter.

Is there any reason *not* to run the cable under the battery box (the
box is up on a short platform, sitting on a sort of shelf, with
clearance for the cable to be clamped to the side of the bulkhead the
battery box is attached to) The battery box is a fully covered/enclosed
USCG approved one, if that makes any diff.

To err is human...to really foul up requires the root password.

You might want to consider the ABYC recommendation which limits the battery
cable run length between your battery(s) and the circuit breaker.. I don't
have the ABYC stuff on this computer but I seem to remember it is only about
12 or so.

Since that didn't work for my installation, I found that I could get around
that requirement by putting the cables in conduit unit I they reach a more
convient location about 30" away. This is where I installed my main fuse (I
think it is 500 amp) and disconnect switch.

(If someone has ABYC handy, please confirm these distance recommendations)

You need a high capacity disconnect switch (on/off) plus a circuit
breaker or fuse as close to the batteries as possible, usually within
a foot or two.

All well and good, but I am aware of this, and it's not the question I
was asking. I am just interested in any reasons I should *not* run the
cables under the batterybox, appropriately secured, and away from
moisture, etc. Since this would shorten the run, it doesn't look like a
problem from my end, but I want to be sure.

Thanks.

I see no reason why youcan't do that. As long as you seal the terminal ends to
keep moisture from migrating through the cable, Go for it!!

Yeah, that adhesive lined heatshrink is great stuff, a bit pricey, but
far cheaper than not using it That and proper lugs that are closed
off so no wire sticks through. Look like a bit of pipe, hammered shut on
one end, and a hole drilled through. Actually, that's probably how they
make them.

AYBC doesn't seem to care if the cables go under the batteries, as long
as the usual caveats are followed, out of the bilges, sealed ends,
tinned copper, well secured, spill proof battery box, etc.

As long as the weight of the battery and box are not resting on the
cable, and the cable is protected from vibration and chafe, it is
probably OK. Not really ideal however. You don't say where the fuse
and disconnect are, but it would be better if at least the fuse came
before the under box excursion.

A buddy of mine spilled some battery acid on things below the battery. He
also got some on the foam cushions. With all the damage that the acid did
he switched to gel batteries. After thinking about it I switched to AGM.
Sailboaters need to deal with angles of heal that can cause problems. I
would avoid anything under a battery that can spill acid.
