Go to Post Mentors need to be sure that the team is on track to have a working robot ready. Students can do almost everything, but they need help watching the calender. Even if your ideas turn out bad, if your robot is inspectable and running when you arrive at your first event, anything can happen. - AcesPease [more]

GAME - Team UPDATE - 2012-02-17
Power Distribution
[R44]
All active circuits shall be wired with appropriately sized wire:

Application
Minimum wire size
40A circuit
12 AWG (2.052mm)
30A circuit
14 AWG (1.628mm)
20A circuit
18 AWG (1.024mm)
between the PD Board and the Analog and/or Solenoid Breakouts if a common power feed is used
between the PD Board and the Analog and/or Solenoid Breakouts if individual power feeds are used
20 AWG (0.8128mm)
between the PD Board and the cRIO
between the PD Board and the wireless bridge
between the PD board and 5A custom circuits
pneumatic valves
24 AWG (0.5106mm)


The branch circuit may include intermediate elements such as COTS connectors, splices, COTS flexible/rolling/sliding contacts, and COTS slip rings, as long as the entire electrical pathway is via appropriately gauged conductors.

Wires that are originally attached to legal devices are part of the device and by default legal as supplied. Such wires are exempt from Rules [R44] and [R45].
And that's the entire update. That's a very reasonable change to make--exempting motor leads from the color requirements (which don't apply to them anyway due to motors not having constant polarity).
