And unless my eyes are getting bad the incoming feeders look the same size at the 200A panel feeders. 3/0 Cu service feeders would only be good for about 225A ... so the main service feeders are probably undersized too (assuming 200A and 100A service panels and MD's) ...
That looks like a Harry Homeowner special (i.e. no permits or inspection), and a red flag in my book ...
BTW ... what was the meter rated at? I would almost bet the ranch it's a 200A meter and utility drop.
