Ground + Neutral question

Hi, I'm looking through B&D's *complete* guide to home wiring; and on page14
it shows the ground attached to the neutral bar with the neutral attached
also, then connected to the various devices independently. I thought the
ground should be an independent wire just in case.
thanks

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

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.

breaker box.
No. Your ground and neutral should be 'bonded' at the service enterance.
