Looking for some help. We recently purchase a factory next to ours and power distribution method in the building we purchased is busduct / bus plugs. I've done a bit of research and it appears that bus plugs are still code compliant. I really want to gut the system and replace it with MCC's. Looking for some valid reason why bus plugs are unsafe, un-reliable or any other arguments to justify the cost of replacement. As always your replies are greatly appreciated.
