Field notes
The proposed probe plan starts with the furnace’s electrical drawings and maps connections across four stages, from rectifiers through furnace cables. The page describes comparisons between connections carrying similar current, rapid-rise flags, and limits referencing NETA MTS and NEC 110.14(C). Its dashboard example is labeled an illustration, so the displayed readings are examples rather than evidence of a live installation.
