Sensor Distribution Circuit Breaker

I am uncertain and unclear on this, but would it be “legal/allowable/permissible” to have a single 20AMP breaker for ALL the sensors on the Robot using a 12V supply.

In my case, the only sensors I have requiring a 12V supply are:
I have 2 Gear Tooth Sensors drawing 16mA each (32mA total)
I have 1 IR Board drawing 19mA

I’d like to simply join the power and grounds together and connect them together at a single 20AMP breaker on the breaker panel. Or would I actually need an individual break for each?


Mike, et al,

All three loads that you mention may be wired to a single circuit breaker. Note that <r47> dictates the size of the circuit breaker for the smallest wire used.
