We were asked by Square D to take a look at a 700 volt DC system at Logan Aluminum in Russellville, KY. The job was to double the existing bus bar system to increase the maximum ampacity. After looking at the job and discussing it with the project management team, we at March Equipment, presented them with calculations showing that the current bus bar system is capable of handling the load that is being added and that there is no reason for Logan Aluminum to spend  money on a bus bar system upgrade.
