Your electrical inspector should study the code. :)
Most electrical inspectors have risen through the ranks of pipe benders,
and by kissing you know what with unions and politicians. There are, of
course, exceptions.
The SOLE reason for the connection of neutral to EARTH is LIGHTNING

Jim,
I believe it is the possibility that neutral may rise several thousand volts
above the ground during thunder storms if it not is connected to ground at the
house entry. You don't have to have a direct hit to induce rather large
voltages on the power grid.
