The house wiring uses the 3-wire 110-0-110 for the 220/240 but the gen

The reason neutral wires are called that is because they are tied to

"The reason neutral wires are called that is because they are tied to
ground" seems to me to be incorrect. True, in US wiring, neutral wires
usually have near-ground voltages on them, but more generally a neutral
wire is one with no current flowing in it when a system is in balance.
In US wiring the neutral CAN have current running through it.

* In a properly balanced load center that current will be minimized ...
so I corrected your statement .
Greetings Terry,
Maybe you can educate me a little. After reading posts in reply to
my post I got out the amp clamp and measured the current on both wires
of the 125 volt receptacles in my shop. Plugging in a motor and
turning it on the meter shows the same current draw on both the
neutral and hot wires.In this case approximately 2.8 amps. I wired my
shop with wire ways so it is easy to make measurements as the wire way
covers come off easily and the wires just lay in the wire way.
All the 125 volt receptacles on one wall are fed from the same
breaker, on another wall another breaker, and so on. I did balance the
load in the breaker panel so that two walls are fed from one leg of
the 250 volt supply and two walls from the the other leg.
I don't understand how the neutral can be balanced and show less
current than the hot except at the breaker panel where the power comes
in. What am I missing? What don't I understand?
I did wire the shop myself but I was helped by a licensed
electrician, the electrical code book, and the wiring was inspected
and bought off by a particularly picky inspector.
Thanks,
Eric
The neutral of a 120/240 circuit is a SHARED neutral.
From the point where the 2 branch circuits join, a balanced circuit
neutral carries no current.
Yes - every branch circuit neutral carries current, but if the load
L1 to neutral and L2 to neutral are exactly equal in both current and
power factor, there is no current flow in the shared neutral.

Take a transformer with a center tapped secondary and put the same
load on each side of the secondary.

Lets say it is a center tapped 24 volt secondary - with 12 volts on
each side of center.
Put 12 ohms across each side. You get 1 amp flowing through each load
to the center tap. You get one amp total current in the secondary - so
what current is flowing in the center tap?
ZERO.

There can be NO OTHER ANSWER.
