This value reports the current reading from current transformer CT2 on the Eaton Genesis II unit, expressed in tenths of an amp, with a special value of -1 meaning that CT channel is not present or unavailable on this particular unit. An admin monitors it to track the electrical load on the circuit sensed by CT2, watching for values approaching the unit's rated capacity as a sign of an overloaded circuit. For example, a reading of 210 indicates 21.0 amps of current on that circuit, which the admin would compare against the circuit's rated breaker size.
