sometime in the early 1980s, but apparently code didn't require updating of
all the outlets at that time (either that, or they just plain shirked it).
All of the "new" circuits are 3-wire, but there are still a few legacy
2-wire circuits in here - terminated in new-ish 3-wire outlets, of course.
?Of course? ? hm. Code allows existing 2-wire circuits to be kept, BUT you are then
required to use 2 prong outlets. Use of 3 prong outlets on a 2 wire branch is a code
violation. So the best fix is to install a ground wire, but failing that the answer is to
use the correct outlet.
