Current Sensing Circuit (mA)

Good Day,
I am trying to sense currents within 2-10mA range. I currently have a Delta to Wye configuration. Each Wye leg has a current limiting resistor to allow me to "short" each leg to each other or to ground and only draw currents between 2-10mA without tripping a breaker.

I want to be able to sense currents on each leg and ground within this current range. The ultimate goal is to immediately trigger a "relay" to indicate if either Phase A, Phase B, Phase C, or Ground had current flowing through it.

Please note that I am not fluent in electronics (However, electronics inputs are welcomed). The most accurate yet simplest solution would be best. I appreciate the help!
