THIS PARTICULAR SCENARIO IS IN MOST MANUFACTURE HOME AT LEAST IN NEVADA, WHERE YOU HAVE A STAND ALONG OR PEDESTAL METER , SOME TIME INSIDE THIS PEDESTAL THERE IS MAIN LOG OR A MAIN BREAKER WITH MORE SPACE FOR OTHER BREAKERS. ONE OF THIS BREAKER FEED THE SUB INSIDE THE HOUSE WHERE ALL BRANCH CIRCUITS ARE DISTRIBUITED. THIS SUB HAS IT IS OWN MAIN BREAKER (SEPARATE BUILDING ) AND ITS OWN BUS RATING. SORRY FOR THE DELAY ..... HERE IS THE QUESTION. ....DOES THE 120% RULE HAS TO APPLY TO THE HOUSE SUBPANEL , STAND ALONG (PEDESTAL ) OR BOTH?

He is talking solar where you can size the solar input to 120% of the main buss. A 200 amp panel would mean 240 amps---40 amps solar.

I believe it only applies to the panel where you input the solar.

No, the 705.12 busbar rules (of which the 120% rule is just the most frequently used option) apply to all panels between the inverters and the utility.
