Subject: | Joining multiple wires |
I'm certain that I've seen this covered, but after searching, I can't find it.
:(
What's the preferred method for taking a single supply to multiple destinations?
Specifically, a fuse block with individual tabs for each fuse.
In my case, I've got four different lighting circuits (cabin, panel, annunicators
and map light). I'm not sure if the best practice is them to be individually
fused, but if something goes awry with one lighting circuit, it would be nice
not to lose all the lights, right? [Wink]
But even if it's okay to put all the lights on the same fuse, I've got a couple
other situations where I need to distribute a wire to two or three destinations.
So what's the best approach for doing this?

Yes, you've articulated the fundamental purpose
for a 'bus' and multiple feeders each enjoying
its own protection. The simple-idea is that such
bus/protection structures prevent catastrophic
damage to wires while keeping faults isolated
to one system. I.e. no single fault propagates across
to other systems.
But even if it's okay to put all the lights on the same fuse, I've
got a couple other situations where I need to distribute a wire to
two or three destinations.
So what's the best approach for doing this?
The mechanics are easy. The value of doing such
a thing is part of your failure mode effects
analysis (FMEA) for YOUR project and how you plan
to use it. If you carry a flashlight in the flight
bag along with your hand-held COMM and GPS radios,
then your FMEA says "Plan C is a considered path
to comfortable termination of flight . . . and ALL
your lighting can be on one fuse.
If the products of your deliberation are not quite
so relaxed, how about half your 'minimal lighting'
on one fuse, other half on second fuse? Maybe you
would find it useful to mount a couple of these guys
http://tinyurl.com/lyeaonf
in brackets on each side of panel as minimalist
flood lighting. Hooked in series and controlled with
a simple dimmer, you could power them from the
bus through a resistor that offers inherent protection
for wiring . . . i.e. no fuse needed. This unique set
of lights would be available if every fuse was popped!
The short answer to your question is: Joining multiple
feeders is easy. Deciding WHICH ones to join and evaluating
the risks during an FMEA takes a bit more thought . . .
something we can assist with but ultimately your
task alone . . .

As I read this, my interpretation is that the answer is to join the multiple wires
at the supply. If that's correct, that could be a problem since the supply
is a pin on a VPX and there may not be space in the connector housing. I'm
not certain because I haven't thought about doing it like this.
If this solution won't work, are there any other methods for distributing a single
wire to multiple destinations?

Don;
Did you read to the very bottom of the page in the link??
The section called "practical example"??
It shows multiple wires originating from a single wire attached to a single
terminal which is, I think, what you're asking to do. (the single wire would
go to your single pin on VPX, the multiple wires to your multiple lights.)

Subject: | Contactor recommendation |
Hello group
Wondering if I can use a 28V cutler hammer 6041 series contactor in a 12V
system?
New Type II contactors are way too expensive and exploring good condition
used ones.
Question is, is it better to use a new inexpensive Type I contactor or a
used Type II.
Are there recommendations for good quality Type I?
TIA

Hmmm.
First of all, what are the items we are talking about?
The Open Source WigWag, Overvolage/Lowvoltage Module, a ground module that ties
DSUB pins to a ground plane?
Such care has gone into these products that it seems a shame to let them die.
I would like to propose a Heath Kit - ish approach to saving these projects.
It seems that the real value is enabling "hands on" type builders to stretch their
skill set by learning to solder/troubleshoot their own electronic hardware.
The final outcome of, for example, having a working WigWag is only slightly
valuable. The skill-set is what is actually the desired outcome.
I have no intention of taking on a labor of love, so this will need to generate
a small amount of income per transaction. I am thinking a markup on complete
kits including circuit boards, cases etcetera.
All data Open Source data, of course. Hopefully supported by some nice How-to videos....
Doesn't exactly sound like a get rich quick scheme.....
Also Bob, do I recall a glancing mention of a all-in-one SERVO/IMU/PROCESSOR for
a wing leveler? Is there any development material there?

For multiple non-critical low power items that you're going to power
from a single fuse, you can always just 'daisy chain' the supply wire.
One wire in the terminal at the VPX, then at the 1st load, insert the
power source wire and a 2nd wire in the terminal. Run that wire to the
2nd load, repeat. This assumes that the total of all loads is lower than
the capacity of the wire, which should be the case anyway if you're
putting them all on the same fuse. (Fuse should always be sized to
protect the smallest wire connected to it.)
Depending on the location of the loads, this can save a bit of wire (and
weight, if you obsess over weight).

Okay, that isn't fair! You just made a basic reply but didn't help alleviate the

Yes. The last picture under "practical example" is one way to connect
multiple wires to a single source when space within the connector may be an
issue. It allows for a single wire into the connector, just as it was
designed for and is an acceptable way to take that single wire to multiple
devices. (assuming the fusing of that single source is properly protecting
the SMALLEST wire attached downstream of it)

All of the original AeroElectric Connection products and
about a dozen new ones will return. They just wont
be manufactured and shipped from here.
Discussions are in the works . . .

Hari, we bought our contactors for our Subaru Eggenfellner 3.6L from B&C.

Marvin, There seems to be a lot of hand wringing and trying to wrest defeat
from the jaws of victory on this list lately. You believe you have been
pointed to an elegant solution to an aspect of the architecture you are
crafting. If you cannot find an adequate reason to abandon that solution,
don't. As my dear departed Grandmother would have said, "Don't throw out
the baby with the bath water".

Subject: | Re: Joining multiple wires |
LOL! Okay, so if it looks like a baby, it likely IS a baby?!!! Good!
Maybe I will survive this wiring project! I can do about anything with
my hands, and have learned a lot of stuff over the years. Plumbing, I
cannot do....I can mess up more in 30 minutes that a good plumber can
fix in a hard day! I can do intricate machine work, compound metal
work, carpentry, cabinetry, welding, electrical, etc. But plumbing is
my waterloo....was about to decide that I could add aviation electrical
to that "can't do" list!
Thanks

http://tinyurl.com/l67uj8hre reference shows a very elegant way to
connect, by my count (8 wires) to a single one wire connector on a
permanent basis. But this post from Don seems to take us back to the
initial problem - not enough space in the original connector to the
device for 7 or 8 wires? Am I correct? Why is that last display not a
very elegant solution to that problem....what am I missing here? Or am
I just stupid? One wire goes into the connector, just like it was
designed. At some point in the run of that wire, where ever it is
appropriate, then you execute the connection as Bob displayed, and the
problem is solved. If not, what am I missing? I keep trying to follow
