I have been reading on all sort of issues and remedies that people
have been suggesting for adding a 3rd ground wire to the outlets.
since the ductwork is steel, as long as you run downstairs and ground
the ductwork to the panel ground, can't you just connect the 3rd wire
of the outlets to the nearest duct outlet using a metal screw?
if this is against the code, is there any reason why? I'm assuming the
ducting is as good a conductor as a 14 wire.
