In no way is that right, see my previous post.
WHY - in a nutshell in the most simple and definitive way I will explain why with a simple question.
"What could happen if a single 100a fuse were to blow in one of the two feeding disconnects?"
Then the second 100amp fuse would blow very quickly after too... since it's immediately gets overlaoded, right? Regardless though there are so many code violations going on here.... feeding a higher amperage panel via two lower amperage panels, uninsulated connectors left exposed, cables attached in a manner that put stress on the fittings, not being able to shut off the load panels with the action of a single cutoff switch, blue load cables plugged into black inputs, old color re-coding tape not removed on other circuits, and who knows what else is done wrong just looking at that amazing quality of workmanship on what is visible on the outside.
