star point

(OP)
my boss has just informed me that if the earth( ground) is connected to star point it will potentially become live is this true

RE: star point

Live Earth?  That would be a new one; ground (earth) is the reference voltage, anything solidly connected to ground is at zero volts.  If there is current flow in the connection, there will be a voltage drop between the point measured and ground, but ground is still at zero.

RE: star point

Connecting the starpoint of a transformer, generator et.c. to ground  is giving you a TN- or TT- system (the first T means solidly grounded neutralpoint). The other letter is determining how your PE-conductor goes.

If the neutral is not connected to ground, you would have a floating neutral, i.e. an IT-system.

RE: star point

Aside: 'T' comes from the Latin word for 'earth', Terra.
