Can someone point me in the correct direction for sizing a manhole/electrical vault. I have 2 runs of (12) 2&1/2 Conduit coming from the utility transformer into the building. We are trying to install a manhole/electrical vault before entering the building. We will be installing duct bank from the utility and then transitioning into rigid metal at the manhole/vault but I am having a hard time figuring out how big the manhole/vault should be. Thanks for any help.
