so 14 is not ok?

Or am I reading it wrong?

In accordance with <R47>:

<R47> All active Power Distribution Board branch circuits shall be wired with appropriately sized wire:
A. 12 AWG (2.052mm) or larger diameter wire must be used for all circuits protected by a 40A circuit breaker.
B. 14 AWG (1.628mm) or larger diameter wire must be used for all circuits protected by a 30A circuit breaker.
C. 18 AWG (1.024mm) or larger diameter wire must be used for all circuits protected by a 20A circuit breaker.
D. 20 AWG (0.8128mm) or larger diameter wire must be used for the power connection between the Power Distribution Board and the cRIO-FRC .
E. 20 AWG (0.8128mm) or larger diameter wire must be used for the power connection between the Power Distribution Board and the Linksys Wireless Bridge
F. 20 AWG (0.8128mm) or larger diameter wire must be used for the power connections between the Power Distribution Board and the Analog Breakouts and/or Solenoid Breakout if individual power feeds are used. 18 AWG or larger diameter wire must be used if a common power feed is used for multiple breakouts.
G. 24 AWG (0.5106mm) or larger diameter wire must be used for providing power to pneumatic valves.

14 AWG wire gets a 30 amp (or smaller) circuit breaker.
