Hey,
I am doing a 200A service change on a commercial building. The existing panel/service have a hub on the top I've never seen before. I am planning to remove the existing panel and replace it with a 200 A meter main from cooper/b line like this one:

But a 200A version.
I was planning to use just the typical type A 2" hub and a nipple like always. But then I open the gutter above the meter to find this (in the photo)

So now I'm stumped, anyone have any suggestions? Make a plate out of metal and use the hub as planned? Is there some sort of listed K/O seal for this? Thanks for the help!

Pretty common setup where you have up to 6 meters. You have that "bussed gutter" with taps down to the socket and main. May I first ask why you need to replace the socket? Is it just shot, or its only 100A? I think my first thought would be to check out price and availability of that socket/disco unit and replace it like for like. If you have to retrofit something, note there is actually no prohibition from cutting/using a hole in two abutting cabinets or wireways (asumming they are bonded appropriately, and the edges are protected with edge guard). I know it seems kinda mongrel, but I have seen very reputable shops do such things.

Edit: I also don't see any problem with patching the hole with 16 guage steel and punching a hole in it for a nipple.
 
yes its only a 100 A and they need 200 for the new shop going in. I was hoping not to have to "patch" the gutter but I think that might be the only way, the guy at the city is a stickler so hopefully we can find a solution.

Thanks for the response.

Sounds like you need to ask him before you do anything.
 
Is perfectly acceptable to fabricate your own covers and junction boxes. As long as you match the thickness of the existing material and provide corrosion resistance and protection from the elements.

The key there is acceptable to who ? :) Talk to your inspector. You are altering a listed assembly.
