Here is an idea that Nicholle came up with for the building of the modules:

To make it easier to measure out distances for things like distance between centerlines from the edge, between lines, etc, she took a section of wood used for stirring paint that we got from Home Depot, and measured out the distances converted from decimal inches to fractional inches and marked them off on the stir stick, making a guide rule that has made laying out the track for "roughing in" on the foam core a lot faster.

Good idea. I am a fan of templates and jigs for repeatable results. Alternatively, I use the 12" combination square (mine had both metrics and imperial gradations).

If no one can find any more faults, I think the wiring standard is done. Again, please check it out and give me your feed back.

Everything looks very good to me. Thanks for your time to get this done. If no one has any objections I'll add it to the standards.

Looks excellent. Should we specify that the outlets are to be positioned rougly around the center of the connecting side? Otherwise, 12" cord may not be enough... But this is nitpicking. Thanks, CSD, for getting it together!

I'm going to add a layout drawing based on a 2' module to supplement this drawing. I will show the basic positioning of all the buses. Putting the bus runs close to the front to shorten the length of the feeders. Here is a picture of my home layout to illustrate. It doesn't use the same amount of buses but you'll get the idea.

Not seeing any objections so I'll add this within the next few days.

Here is a suggestion: As far as the connecting plugs, perhaps there should be a color code as to what is getting connected (i.e. Inner line, Outer Line, Acc. AC Power), with either the face of the outlet plug painted or a colored tag next to each plug.

Sounds fine to me. The colour code should be the same as the wiring to avoid confusion and the buses/plugs should be laid out in the same order as the drawing with the AC aux bus/plug (pink/purple) in front and the inside track power bus/plug (red/black) toward the back. You could also write the bus name on or next to the plug with a felt.

On a separate subject, I would like to note that even if you are not using one of the buses, i.e. all your aux devices are DC, you are still required to install the all the buses for interconnectivity of the modules.

Absolutely.
