Electric systems can be compared to water systems
Imagine two tanks of water.. One has a pipe coming out of it goign to a pump, this pump pumps water into the other tank but there is a "T" fitting and connected to the other side of the "T" is a 2nd pump pumping water BACK into the main tank.
THe pumps are L-1 and L-2 the 2nd tank or rather the pipe connecting it to the :"T" is the "Neutral".
So long as both pumps are running exactly the same current (Gallons per minute) There is NO water flowing in the "Neutral" pipe it's just going around in circles.
But shut one of the pumps off and the "Neutral" line is now carrying whatever trhe other pump is pushing up to 50 GPM,
And that is how it works. Pressure (Between neutral and L-1/L-2) depends on if both pumps are running..
Now,,, Imagine the "neutral" pipe is clogged.. The running pump is going to create quite a bit of pressure (or vaccum) at teh "T" fitting.
