Al, it appears to me that the info in the sensor manual specifies a 24 AWG power cable (in the form of a PWM cable) to connect the 12V power connection on the sensor to the 20A sensor circuit breaker, while <R47> specifies that we must use 18 AWG wire for all circuits protected by 20A circuit breakers.

Do you see the source of our confusion? Does the sensor manual information have priority over the rule? That doesn't make sense.....
