Let is also not forget the complexity of Computed Loads in determining the actual size of the SEC.....does play a factor.....but alas that gets WAY to techinical and outside of the scope for Home Inspectors.

Unfortunately, as regards the particular panel pictured, you left-out the fifth multiple choice answer:

Count the amperage of all remaining breakers that DIDN'T jump-off the buses when you removed the panel cover

As usual....great Topic gerry.......Thanks for your continued efforts to bring electrical issues to the forefront...it is the largest concern of HI's..because of the dangers and if anyone has actually seen someone get electrocuted like I have...they will respect the importance of electrical knowledge every day.

Thanks again for all you do.....

Hi to all,

The correct answers are:

The rating of the SEC's
The rating of the panel enclosure

As there is no single main disconnect, the ratings of the multiple breakers tell you nothing.

Regards

Gerry
