The ground-to-energize configuration for battery contactors has been around for a very long time and I suspect thought about many times. I've not had a discussion with folks over in the bent-metal department about it. They have noted over the history of their careers digging through the pieces that when the battery is ejected from the fuselage on impact, the airplane catches fire fewer times than if the battery is contained. An anecdotal observation at best. I've dug through piles of bent-metal quite a few times too and I would offer this observation. For the insulation on a wire to be compromised mechanically takes force. Fat wires will resist the forces of crumpling metal thus placing insulation a greater risk than would a 22 or 20 AWG wire that is flexible and morel likely than not, relatively protected by other wires in the bundle. Probability of compromising insulation on a strand of 20AWG wire versus 4 or 2AWG wire from the same scenario is very small. You could drive the battery contactor from the battery bus through a small fuse if you wish.

Don VS Brass and copper are fine . . . in fact, brass is a little less reactive and probably better. You can purchase brass strip stock from many hardware and hobby stores from the K&S Metals display that will look something like this: http://www.ksmetals.com/HobbyMerchandisers/jumbo_metal.asp?Title=Hobby_Merchandisers These displays will include .032 thick x 1/2" strips in various lengths depending on how big a display the merchant chooses to put on his floor. A singl, .032" x 1/2" strip is fine. No need to double-up. If necessary to "splice" a bus, solder the two pieces together in a 1/2" overlap centered on one of the breaker screws. Of course, one can always cut their own bus bar material from flat stock. This same material can be used to fabricate jumpers between fat terminals of contactors mounted adjacent to each other. Don't depend on a screw to maintain bus integrity. Here's a how-not-to- do it series of pictures: http://www.aeroelectric.com/Pictures/Breakers/Bus_Bar_Not_1.jpg http://www.aeroelectric.com/Pictures/Breakers/Bus_Bar_Not_2.jpg http://www.aeroelectric.com/Pictures/Breakers/Bus_Bar_Not_3.jpg This bus bar and breaker assembly was pulled from a certified aircraft. All indications were that the assembly left the factory in this condition. One loose screw kills all the downstream connections to the bus . . . meaning that the "bus" was not a bus.

I recall I was even hand-assembling design elements to make a molex plug symbol. By the time I was done, I realized the components I had custom-modeled were not to any kind of reasonable scale with each other, so I gave up on the whole undertaking. I'm sure it's doable, but I decided it lacked the level of user-friendliness I desired.

It has a schematic and a board drawing component. I find it easy to use whether to draw schematics from which to use as an aid to help you make the right connections on your board design (it highlights all connections that should go together when you click on a component) or skip the schematic phase and go straight to a board design. It does have some limitations compared to the more up end design tools, but the learning curve is not bad, the number of components in their library reasonable (although you always would like more) and you can actually create your own components and hold them in a library for repeated use. Some tools will not let you do a board unless you lay out a schematic first (which is probably not a bad idea), I like the freedom to start with a board design if I think it simple enough. And as mentioned the software is free. The cost of 3 boards (restricted to 3.8x2.5") is $59. The boards are well made and come with a layer of solder on the copper traces (which makes it much easier to solder components). There are other board options of course (costing more I might add), but I have found them very responsive. It includes them even duplicating a board order when the one they originally shipped went awry at no cost.

However, be sure that you have some simple controller/regulator that will prevent the charge voltage from exceeding approx. 13.3 volts. A panel with current output as low as 0.25 amp can gas out a lead acid battery if left connected long enough in bright sunlight. I suspect a small panel with a current limitations of 0.1 amp or less may not really require a controller but, it would not hurt to have a simple zener diode with a gate of 13.3 - 13.6 volts.

I wish I had spent that keyboard time last year day-trading; I'd have more to show for it ;-) I ended up with switch symbols that were 5x the size of all the other standard components - it looked hideous.

Ever look at EAGLE (freeware) pcb layout? They have quite a few libraries. http://www.cadsoft.de/freeware.htm Jim Baker 580.788.2779 '71 SV, 492TC Elmore City, OK ________________________________ Message 19 ____________________________________ Time: 04:33:34 PM PST US From: rv-9a-online Subject: Re: AeroElectric-List: PCB Express --> AeroElectric-List message posted by: rv-9a-online Here is a direct link to a complete aircraft electrical system design (for an RV-9A) and a component library that includes several of B&C's progressive transfer switches etc. It is due for an update (to remove the alternator OVP contactor), but it is complete otherwise. http://vx-aviation.com/page_3.html Vern Little Jim Baker wrote: >--> AeroElectric-List message posted by: "Jim Baker" > > > >>Does anyone have a component library already done that I could >> >> >import? > >Ever look at EAGLE (freeware) pcb layout?

Very appropriate during this Christmas season. I have added your components to my library.

I've had invitations from many folks for, "If you'll link to my website, I'll link to yours." I had a links page for several years and it grew like a fungus along with the hours required to make sure it stayed current. I finally abandoned the effort and established a policy of "no links". A few folks noted that I DID have a link to B&C. Yes. I actively supported B&C for three years or so after they acquired my parts business. Now that I've started developing a line of products completely unique to the 'Connection, my business model calls for a focused effort toward those goals. Further, B&C's web-presence is solid enough that it doesn't need my solitary link. So when the next invitation to join a Mutual Linking Society comes along, I can accurately fall back on the current policy. Perhaps one day when I'm grossing a couple hundred grand a year, I'll hire someone to manage that sort of effort. But aside from being a good neighbor on the 'net, it's going to be hard to justify it from the perspective of return on investment.

The outputs are well documented file formats parsable with perl, or other tools.
