Wet Boots,
Time to learn me some more
Obviously I was busy typing up my response when you already posted yours and obviously our statements are in conflict.
What is wrong with burying a DC (assuming that it's in a meter box where it can be accessed for testing).
(Let's not even get into my statements of burying an RPZ. I've read that it can be done, but only in very special situations, say the side of a hill where the meterbox has a 6" drain hole that discharges out the side of the hill... or something like that).
