    Switchboard feeder breaker load side feeder cables to trough bus are 2 sets of 4-600 kcmil 2/0G protected by 2500 amps bolted pressure switch upstream.

    The conductors to one of the tenants disconnect from the trough bus is 4-600 kcmil, 3/0G.

    The conductors to second tenant disconnect from the trough bus is 4-600 kcmil, 3/0G.

    That should have been the description from the beginning.

    If the 2500 amp FEEDER terminates on a buss, then the (2) Disconnects that are tapped off of it are Feeder Taps.

    Although the cable size for the 2500 amp feeder seem to be lacking some what.

    Slight edit to feeder cable size for those who pay attention since protected by 2500 amps bolted switch:

    Switchboard feeder breaker load side feeder cables to trough bus are 7 sets of 4-500 kcmil 350kcmil G protected by 2500 amps bolted pressure switch upstream.

    No, you've been told about doing this before. When you start a thread include the pertinent information from the start.

    Start a new thread with all the info.
