R621       *Protect circuits with appropriate circuit breakers. Each branch circuit must be protected by 1 and only 1 circuit breaker or fuse on the PDP/PDH per Table 9‑3. No other electrical load can be connected to the breaker or fuse supplying this circuit.

R622       *Use appropriately sized wire. All circuits shall be wired with appropriately sized insulated copper wire (Signal Level cables don’t have to be copper):

R618       *Use PDP/PDH terminals as designed. Only 1 wire shall be connected to each terminal on the PDP/PDH.

R625       *Don’t modify critical power paths. Custom Circuits shall not directly alter the power pathways between the Robot battery, PDP/PDH, motor controllers, relays (per R503-B), motors and actuators (per R501), pneumatic solenoid valves, or other elements of the Robot control system (items explicitly mentioned in R701). Custom high impedance voltage monitoring or low impedance current monitoring circuitry connected to the Robot’s electrical system is acceptable, if the effect on the Robot outputs is inconsequential.
