When I first saw this thread I thought I knew what was going on. I had a Siemens panel with the interior mounted too low a couple of years ago. I see from the photos thias isn't the case. Siemens changed the mains a couple of years ago. It is a completely different set-up as far as the 200A main is concerned. I have a shelf full of the "new" 200A mains I removed from MB loadcenters when I needed a 40ct ML and my rebate made the MB cheaper.I am the only place in my area that stocks the new 200A ITE MB. GE Powerline Gold panels still use the 4 pole 200A main design. GE/Siemens may look the same but I don't like to mix and match CBs in a loadcenter. I have seen my share of Bryant type loadcenters with Challenger, Westinghouse, Bryant, General Switch, GE, Sylvania, Murray and Siemens CBs all mixed in. The true mark of a long succession of handymen.
