outlet2Current is a read-only integer (0 to 2000) reporting the current draw of outlet 2 on the Unity PDU, expressed in hundredths of an amp. This lets an admin see exactly how much load the single device plugged into outlet 2 is pulling, which is finer-grained than the branch-level current totals and useful for spotting one specific piece of equipment drawing more than expected. For example, if outlet2Current climbs from a steady 150 (1.50 A) to 800 (8.00 A) on a receptacle feeding a top-of-rack switch, an admin would flag outlet 2 specifically as the source of the load increase rather than just seeing the branch total rise.
