[sdiy] iec connector confusion

[Nathan Reeves]

Doesn't the L & N switch 60 times a second?  I am confused with mains
power.....

AC in the USA is at 120V 60Hz correct?  So one goes 120V then the other?

On an IEC plug, one is white, the other black and the ground is green with a
screw down loop on it....

Doesn't the L and N wires switch back and forth anyway, so it doesn't
matter?

Cheers,

Nate

You've just made me think - I was thinking it was 230V because he'd said
he was connecting across 4 & 1 - however, I didn't realise the 120V was
also done in that way (according to the datasheet).

So, Dan, make sure you have the two jumpers across 1 & 3 and also 2 & 4.

I'd always treat N the same as L no matter where in the world I was
(i.e. keep well away!)
