I'm not an expert, but i have owned residential and private property in
the past. You don't mention if the installers did anything to your
indoor wireing, to bring it up to a 200 amp? The smaller switches
usually are 15, 20, 25 and 40 amps totally up to or just under 100. Now
with 200 amp you should have more circuits adding up to just under or
200. Take a good look and add up all those circuits.
