I got some lamp cord from Lowe's, but can't seem to find the markings. How
do you know which is + and -?

Thanks

Hi Jiyang,

Your lamp uses alternating current.
There is no plus and minus.
Don't care about it.

Cheers

When using it as speaker wire? You should be able to improvise a
continuity test. Or connect both speakers, place them close together
and reverse polarity on one speaker until you get maximum bass. Then
the speakers are in correct phase.

Hi,
I'm using the lamp cord as speaker cables though.

Thanks

One side usually has an extra rib or ridge running the length of it. Look
carefully as it is easy to miss.

If there is no ridge, some wire has a rounded side and a square side,
others have small symbols printed on one side only. Some wire has one
wire as silver colored and the other copper colored.

.... and some has a colored thread with one of the conductors.

If you look very carefully at the edges of the lamp cord, on one side,
there should be a set of very thin rib like lines that run along its
length. As for the speaker connections, this rib line can be used for
the positive side, if you desire.

The idea of this rib line, is that when the lamp cord is used for
electrical work, there is an easy reference to know where you would be
putting the neutral side. To be compliant, appliances must be wired
correctly in order to meet safety standards. The neutral must always be
in part of the return path that eventually leads to ground.

The other way to know, is to verify the wire with an ohm meter, and then
mark the ends.

Thanks for all the help. Is the ribbed side always +?

As long as you're consistent it doesn't matter.

If you want it to be.

As long as you are consistent, it will not matter. I personally use the
ribbed side as the positive.
