Does anyone have the expected current draw of AFCIs? If they draw a few watts each multiplied by 20 breakers, that could be a pretty significant consumption.
It seem to me that having a pair (for redundancy) of tiny computers in the cabinet monitoring all circuits would be more efficient. If the computer in each CB is drawing only a few milliwatts, then it is no big deal.
On a related matter, I wonder how much juice the surge suppressors use and how much money the electric company makes selling spikes that are shunted to earth by the surge suppressors.
