5 amp circuit breakers

According to the wiring diagram, we are supposed to put the wires on the "max 30" amp curcuit breakers. But we found another wiring diagram (In Part 3 of the Controls System Manual) that says we should use a 5 amp circuit breaker. The problem is that this diagram comes with a disclamer "This Diagram may not comply with all FIRST rules." Can someone please help us?

Thank you!

Don't confuse the control system manual with the rules. The control system manual tells you how things can be connected and used, the rules (specifically section 8) tell you how things must be connected for FRC.

<R46C> says that the digital sidecar must be protected by a 20amp breaker. <R47C> says that everything protected by a 20amp breaker must use 18awg wire or larger.

If you were doing this for fun, you could use a 5amp breaker and 22awg wire safely. As you pointed out, it isn't safe to use a 20amp breaker and 22awg wire.
