110.26(C)(2) Large Equipment

What about a 1200 amp tap can with 6-4high 100 amp meter bases on each side. (48 units) Each meter stack is rated 800 amps. Another scenario; What if you have a 1200 amp main breaker and all the meter stacks are rated 1200 amps? Should this electrical room require two doors? Or just double the working space infront of the 1200 amp main breaker?

The entire gear is rated 1200 amp so why you suggesting just in front of the 1200 amp main breaker?

There is still similar potential fault energy at one end as there is at the other as well as at the main. It will vary some but length of buses is short enough it will not vary much.
