One of the PV Salesmen i install for sold an 8kv kw system to a customer with a 150 amp service. My first thought was to include a service panel upgrade to 200amp with my estimate. While discussing this, the customer mentioned that most manufactures use the same size buss bars in 150 and 200 amp panels.
i have been to Eatons site and Square D's site and can find no data or cut sheets on the actual physical size of the buss bar. Can i use standard buss ratings of 1000amps per square inch, or just 120% and thats it?
