    Subject: Joining multiple wires
    From: "donjohnston" <don@velocity-xl.com>
    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? Read this topic online here: http://forums.matronics.com/viewtopic.php?p=418865#418865

    What's the preferred method for taking a single supply to multiple destinations? Specifically, a fuse block with individual tabs for each fuse. Here's a couple suggestions on the mechanics of the task . . . http://tinyurl.com/l67uj8h 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] 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 . . . Bob . . .

    Subject: Contactor recommendation
    From: Hariharan Gopalan <rdu.hari@gmail.com>
    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 Hari

    From: "toddheffley" <public@toddheffley.com>
    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?

    I guess I am a dumb cluck, but following this thread, I do NOT understand the problem, and I am a lurker trying to learn before I tackle my panel. From Bob's posting the very last display on his 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 along with these wiring discussions about the proper ways to make connections and route wiring, and I just get lost with the on and on discussion, because I MUST NOT understand the problem since I believe I saw a very elegant answer several posts before either by Bob or others on the group. I have just let it go as a fact that I am just stupid, but this discussion is a good example, and I would appreciate someone explaining to me what I am missing so I can finally alleviate my perpetual "stupidity" condition!

    Okay, that isn't fair! You just made a basic reply but didn't help alleviate the "stupidity factor"!!! - Best practice is that last display for connection to a single wire connector? Multiple components driven by that wire makes that specific type of connection appropriate? Sorry, but I am trying to eliminate some confusion on my part! M.

    Subject: Re: Joining multiple wires
    Marvin; 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) Bob McC > -----Original Message----- > From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list- > server@matronics.com] On Behalf Of H.

    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!
