I recently inspected a 1960's era 6 throw panel that has been modified and was a little odd. It was no longer a 6 six throw, I think. In the pictures below you may be able to see that the feed from main lug to the lower section of the right bus has been disconnected. The two pole disconnect that I would expect to see feeding the lower section of the bus has been replaced with two sets of mini breakers. How is the lower section of the right bus being supplied with power? Click to Enlarge 45.75 KB Click to Enlarge 50.4 KB Click to Enlarge 44.15 KB Click to Enlarge 35.15 KB
