I am having difficulty understanding wire bending space considerations. Have a set of panelboard guts to install in an exisitng enclosure and have been told that the newer enclosures are longer to provide for newer requirements of wire bending space. In this case the conductors enter on the bottom of the enclosure and go up to the the top and loop 180 deg in a nice clean loop down to the lugs. not sure what the exisiting space is but need to make sure to remount the new interior so that the correct space is maintained. I think this can be done but am not certain which table to use to calculate it. It is a 250 amp 42 space interior with I think 4/0 cu conductors existing. Dont want to change the can because of the way all the rigid piping comes in. Its 3 blocked and would require a major deal to change the can.new can is 6 inches longer thatn the old one. This is in a restaurant chain store and cant shut this panel down for more than overnite.
