Motor Wire Specs?

What are the wire Gauges for cim, window, and gear motors? any help is appreciated. thanks!

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].

Thus, it depends on what fuse they are hooked up to. CIM motors will always have to be 40 amp though, and controlled by a Jaguar or Victor.

As part of a team who suffered greatly from someone’s misunderstanding of “minimum”, I want to clarify that it means “minimum diameter”, not “minimum gauge number”. Wire gauges are very unintuitive in that the number gets smaller as the size increases.

Last year, we were re-inspected on Friday because we had managed to get an overweight component within the limit. We had an inspector who thought that we had to have wires larger than the minimum in terms of gauge, and made us re-wire in the pit with 16 AWG wire on all our motors (I guess we didn’t have any 20A circuits that year). Once we had finished that, missing a match or two in the process, another inspector came by to verify we had done it correctly. This one understood the sizing chart and told us (correctly this time) that all our wires were too small. We had to change it all back, missing another few matches. Needless to say, we didn’t rank very high that year.

Morals of the story: sometimes, the inspector is wrong; and to be completely safe, use the size that will be legal no matter which way the rules are interpreted.
