why have it in the circuit at all?...?

Question

if the presence of the ground point in the circuit provides an easy point of contact for someone to get shocked..

Answer 1

considering the ground is copper and driven deep into the earth, the electricity takes the least resistant path to ground.... you have shoes on and the human body has a high resistance... if you were sweaty and barefoot in a muddy mineral rich puddle of water, then i would worry it would cause a parallel path through my body as well as the ground rod, but unlikely... you both have the same potential.. 0..

ground wires do not have current flow unless there is a short circuit and the over current protection device should open immediately..... the neutral has current flow

Answer 2

The ground point should be at zero potential if it is properly earthed.In that case you will not get shock if you touch the ground point.But ,if the ground point is not properly earthed and there is short-circuit ,you will get a shock if you touch the ground point.In this case human body becomes an easy path for the current to pass through.If the earth is proper and there is a short circuit ,the fuse will be immediately blown off before you touch it.So, earthing through the ground point is a safety measure.

Answer 3

That is why you have a ground point. So you can't get a shock from touching the chassis.
