Open service neutral danger.

[Miguel c]

If a situation like the one shown in the picture occurs, Where the neutral conductor is open, so we no longer have an effective ground fault current path, how does the NEC guarantee safety?

The NEC can't and doesn't guarantee anything.

The situational image shows why our work is so important to get right.

So correct.

Never lick an "open" neutral with your tongue when there is a load on the circuit to "check for safety". Use common sense, I you have it, it's better than the NEC sometimes. Just sayin' ;-)

 

[LarryFine]

A neutral (beyond the service) should be treated as any ungrounded conductor.

Besides, the main purpose of the NEC is the practical safeguarding of persons and property from hazards arising from the use of electricity (Art.90.1(a)) on the PREMISES, that's no include any failure in the services conductors. See Art.90.2 Scope.
