Your house feed is already on a grounded center-tapped secondary.  That's how
you get 120V for your lights, etc., and 240V for your water heater, etc.

The neutral (white) wire on your 120V outlets is connected to the
distribution transformer center tap.  The hot (black) wire is connected to
one or the other end of the secondary winding.

If you look at a 240V outlet, you will see two hot wires (typically one
black and one red, but they can be any color except white or green), a
ground wire (green or bare) that MUST NOT carry current, and maybe a white
neutral that can be a current carrier.  The ground is required for safety.
The neutral is needed only if you require dual voltages from the outlet.
