Nope, Ground and Neutral are always hooked together and often grounded
at the breaker box. That is one of the reasons that GFCIs work. Any
leakage current will take the ground path, therefore less current will
flow in the Neutral causing it to trip.
What needs to be avoided it to have them connected at multiple locations.
Lots of web sites with more detail. For example:
clarification the ground and neutral are common ONLY at the service. Every
where else they are seperate. Breaker box could be any location
That is one of the reasons that GFCIs work. Any
The "often" apparently is not always. Perhaps should read "almost
always". The below reference says:
the neutral and earth join together at the service intake; in others,
they run completely separately back to the transformer neutral terminal,
and in others they are kept completely separate with the house earth
having its own rod and the neutral being rodded down to earth within the
distribution network. In a few cases, they are combined in house wiring,
but the dangers of broken neutrals and the cost of the special cables
needed to mitigate this mean that it is rarely done nowadays.
