Ampacity of the bus bar selected must then be verified by checking table 1.
Copper bus bar ampacity.
110 busbars ampacities in the table below are for bus bars having an emissivity of 0 4.
This was observed on samples exposed for 60 days in an industrial environment and it is probably identical to that of bus bars in service.
Ampacity of the bus bar selected must then be verified by checking the ampacity table.
Ampacities of bus bar systems of other configurations must be calculated taking into account size spacing number of bus bars and overall skin effect ratio.
