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 early warning current threshold for the X-Y phase-pair of circuit 2, set lower than the hard xy2MaxCurr ceiling. Crossing this warning level lets an administrator see circuit 2's X-Y leg trending toward overload and rebalance connected loads before the stricter maximum-current limit is ever reached. For instance, setting xy2WarnHiCurr to 1400 (14.00A) would raise an early alert on X-Y well before its current approaches the 16.00A hard limit typically used for xy2MaxCurr.
