>If one line has a large load relative to the other, the neutral won't be that close to ground. Shouldn't it still be pretty close voltage wise? If we hold the neutral is always at 0v at the panel, since that's where it's tied to ground, the voltage on the neutral between the panel and the outlet should still be pretty low because copper wire has a pretty low resistance (by V=IR). I'd have to break out my calculator (and look up the actual standard values of copper wire resistance), but I'd guess even >20V would be quite unusual without some other fault...
