Question on splicing feeders for new transformer

[legato]

Hi everyone,

Is there any know restriction of using a copper busbar to be used as a termination point to connect 6 existing feeders at 300MCM to 4 new feeders at 350MCM?

The busbar is rated to exceed 1200A per the manufacturer.

I cannot locate any code requirement stating busbar cannot be used in such a manner.

The 6 existing feeders were originally secondary cables for 3 single-phase pmts that were tied together to make a 3-phase 120/208V system.

The 4 new feeders are coming off a new pad mount utility xfmr to a new 1200A 3-pole breaker and hopefully terminate at that busbar.

Thanks in advance.

Can't answer your question but why not use a distribution block?

This one from Ilsco looks like it would work PDB-49-500-1.

Thank you for the suggestion on that. But I think we may have found an answer...Bussed gutters that are pre-built with copper busbars and the whole unit is UL listed. It may cost more, but I think this will resolve the issue with our local building dept.
