According to Toller :

So you say, but cite an incident.

Do google searches on this group and misc.consumers.house. I remember seeing
at least 3-4 confirmed open main neutrals leading to extremely strange problems
being reported and discussed.

I know the problem is that if the neutral connection at the breaker box
opens, the chassis is potentially hot. Aside from being unlikely (what is
the last time you had a neutral connection at the breaker box open?) it is
dumb. If the chassis is hot, it is because there is an open circuit. If
there is an open circuit, the appliance will not be working.

Incorrect. If the main neutral opens, 240 devices (ie: stove elements) won't
notice a thing awry. If the load on the two legs is roughly equal, the
120V devices will continue to work _too_.
