I just returned from northern BC Canada, wiring wooden wall tent platforms
for lights. I searched all over the NEC for rules regarding wiring tents,
and couldn't find a single reference! Go figure.
The tents are spread out away from the power center, so it's 120vac from a
1kW Magnum MME inverter
Ray,
If golf cart batteries can't surge over 2000 amps, then it would seem
that the fuse in line with the QO can be deleted in some cases. Is
the 2000 A surge for one 6 volt battery or 2 in series?
Fuses can be put in the QO enclosure ahead of the loads and DC rated
Class T fuses can be
I'm not sure about the price, but what about using the DC enclosure from an
Outback Flexware system? Lots of space for branch circuit breakers, plus a
big DC disconnect.

I like the Midnite MNDC series.low
cost, with lots of room for future expansion.
List price around $225
I like Maverick's suggestion of using a combiner box, even lower
cost.

On the cheap side, Square D QO. They are indeed rated to 48VDC, which means
you can use them with a 24v system (but NOT a 48v system). If there is an
inverter too, the Midnite mini-panel ($160 with main breaker) and DIN-rail
DC breakers.

Great ideas. I think for this job I will use the combiner box idea. I do have
an old trace disconnect box as mentioned laying around that would work as well.
Since I'm only putting in a couple DC lights, the combiner method should work
great. I get a lot of fish house and hunting shack
The problem with many of the suggestions, is that these Micro 12 v systems
generally have budgets under $1000 parts. 20% of the budget allocated to
breakers and discos isn't reasonable, same with a Trimetric.
The ATC fuses are used for literally billions of 12 v circuits that all of you
use
I second using QO load centers. You will want to put a fuse, like an
FRN-R, between the battery and the load center, as the QO breakers
don't have a high AIC rating. 12 V systems can be wired as easily as
a regular AC system.

The QO breaker has an AIC of 5000 amps. The usual golf cart batteries have a
short circuit current of about 2000 amps, so you could do a set of 4 golf cart
batteries at 12v, without worrying about the extra fuse.
Once again, if the system gets any bigger, they should just go to an inverter
The code compliance part has been my worry. The small DC system seems to be
full of code problems. I do see the benefit of the DC only for the fish houses,
but the hunting shacks make me always think code. I have used the morningstar

supply parts and advice, and let them do it themselves.

Hello,
I've been looking at a lot of hunting shacks, fish houses and other 12V loads
setups and was wondering how people go about setting these up? What are people
using for load termination, fusing?
I'd like to keep all disconnects and fusing in one box.

Square D QO is listed to 24V DC according to some of their literature.

We use solar combiner boxes. For instance, the first breaker is actually a 63A
for the Main and then you could have load breakers for each circuit.

panelboards and stuff the price just skyrockets.
Thanks eh!

Actually if you want to really keep the price down, you can use a 12 v ATC fuse
block from Del City wire.
I only use it for RVs, autos, and temporary structures (like fish houses).
12 vdc has its place in Micro systems, but it quickly becomes ridiculous, as
soon as you want more than a couple
