Q200 Clarification on intersectionality of R40 and R56

Post by Robot »

Q200: Per R40, "no additional devices or modifications" are allowed between the battery, main breaker, and power distribution system. However, R56 states that high impedance monitoring that is non-consequential is acceptable in the electrical system. If a team desires to monitor their main power, does R56 take precedence over R40? Can this be clarified to enable monitoring of the main power source?
A:
Doing something permitted by one rule in a way that violates another rule is not permitted, unless that 2nd rule calls out the something as an exception to the rule. That is the case here. Doing something permitted by !R56 in a way that !R40 prohibits is still a violation of !R40 and not permitted. For suggestions, recommendation, and feedback, please reach out to [FRC Team Support](mailto:firstroboticscompetition@firstinspires.org).
