[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]](http://frc-manual.usfirst.org/viewSingleItemMap/684) and [R45]](http://frc-manual.usfirst.org/viewSingleItemMap/685).

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).

Are you talking OEM wires attached to a motor? I wonder if we can use speaker wire that is not read/black for motors?

TIA

The update seems to only apply to that OEM wire with the keywords of “wires that are originally attached.”
