L1 * * * * *N * * * * *L2
| * * * * * | * * * * * |
|____@@_____|____@@_____|
* Outlet 1 * *Outlet 2


Are these statements correct using the above simple MW circuit?


If you lose the neutral and have a lamp plugged into Outlet 1 and
nothing in Outlet 2 the lamp won t work.


Correct, just as in most circuits, no neutral = not operating.



If you lose the neutral and have a lamp plugged into Outlet 1 you will
have the potential of 220V at Outlet 2.


Wrong. You will have 240V across BOTH circuits, if both lamps are the same
wattage, that will provide 120V for each. Most power supply is now 120V not
110V.


Professorpaul is correct. Actually, you're both correct. It's also
important
to define between which two points we're measuring.
With a lamp plugged into outlet one, at outlet 2 with a high impedance
VOM you'd measu

Across the two outlet terminals: 240V
From either terminal to ground: 120V
