This read-write integer, in hundredths of an amp (0-2000, i.e. up to 20.00A) with 0 meaning the limit is disabled, sets the minimum current the X-Y phase-pair of circuit 1 should be drawing under normal load. A reading that falls below this floor on X-Y can indicate that a downstream device has failed, been unplugged, or that a wiring path on circuit 1 has broken, none of which a simple overload check would catch. For example, setting xy1MinCurr to 100 (1.00A) lets the PDU flag circuit 1's X-Y leg if its draw unexpectedly drops under 1 amp, signaling a load that has gone dark.
