What is L and N

--- From the .pdf,

"Wires are soldered from the base of the socket to line (L) and neutral (N) on the PCB."

In the US, common 120V mains are obtained from one of the ends and the neutral of a center-tapped 240V secondary of a transformer. 'L' (line) refers to either of the ends of the transformer, and 'N' (neutral) refers to the center tap.

Sometimes the separate ends of the transformer are referred to as 'L1' and 'L2' in order to differentiate between them since they're 180° out of phase with each other with respect to the center tap.

Sometimes I see on schematics L and N. I dont know that this is. Sometimes I see it in relation to pic schematics. I dont use pic and dont really know anything about it accept that it is a series of programmable chips often for hobbyists.

Here is an example

I have no intention of building this but just show it here as an one example.

L = Hot side of your AC line, normally the Black wire. N = Neutral, normally the white wire. this wire is the one that is connected to ground in the US at some given point out side your home, normally on the pole ground and your house ground coming in. the green wire is normally your own supplied ground around your property to insure user and polarity safety.

Thanks All.

I get it now.

Another diagram is here.

On a 120v AC socket (if the polarity is right), the L is the small rectangle hole and the N is the large rectagle hole. Not to be confused with the 3erd prong which is ground.(green)
