On a main panel, (residential) I believe the maximun panel size is 42 or 44 spaces. A sub-panel can be added if needed.
Ok, what is the maximum amount of spaces that can be used if adding a 60a, or 100a or 125a from a main panel?
Also, Could I use ..lets say a 100 amp sun-panel, fed with #8 wire 40amp, - or
#6 wire 50amp. Any code issues using a smaller wire and breaker (matched of course), and being fed to the 100 amp (having more spaces)?
Any help would be great! - articles in code book covering this?
