AGS electrician measured the loads of all circuit breakers at the
breaker panel A,B,C & E.  All breakers are 20A, except the double
breaker labelled like 21-23 that is 208V, 20A.

Note:  When panel E was installed, neutral wires were not moved into
       panel E.  Thus it caused current imbalances in the covered cable
       trays that caused ground noises.  The total ground current upstairs
       was reduced from 11.5A to 3.3A after the neutrals wires were properly
       installed.
       Further inspection found CB 40A has a 1.5A ground current and further
       this is from one of the fan module on top of rack L15.  Replacing
       this module results in 0 ground current in 40A and reduces total
       ground current from 3.3A to 2.5A.
