Aside from the rule itself, I don't see references to <R56> anywhere in the 2006 robot manual. It certainly isn't mentioned in the section on custom circuits.

I interpret that to mean "if you are using 12v, you need to use a fuse". |
One of us is very confused, and I don't think it's me. Fuses are mentioned in <R57>, not <R56>, and are designated there as
permitted, not as mandatory. The circuit breaker is mandatory in any case.

The 5v from the RC is for sensors. Rule <R91> about powering custom circuits is explicit. I also repeat the mention from <R57> here in its full context.

In addition to the required branch power circuit breaker, smaller value fuses may be incorporated in the custom circuits for additional protection. All outputs from the custom circuits must be connected to the analog inputs, digital I/O, TTL Serial Port, or Program Port on the Robot Controller.
