currentyz2 is a read-only integer (0 to 2000) reporting the YZ line current on branch 2 of the Unity PDU, expressed in hundredths of an amp. This lets an admin see the actual electrical load carried by the YZ leg of branch 2 independently of the PDU's other phase pairs, which is essential for spotting an unbalanced load before it trips a breaker. For example, if currentyz2 reads 1450 (14.50 A) while the PDU's other legs sit near 800, an admin would recognize branch 2's YZ leg is carrying a disproportionate share of the connected equipment and consider redistributing outlets.
