The ribbed side of the line cord indicates the
neutral wire
Neutral is a circuit conductor that normally completes the circuit back to the source. Neutral is usually connected to ground (earth) at the main electrical panel, street drop, or meter, and also at the final step-down transformer of the supply.

Which wire is hot smooth or rough?
Wires can also be coded by texture rather than color. If the wire feels smooth and has no markings, this is the hot wire. In comparison, the neutral wire feels rough or has stripes or markings.Is the ribbed wire hot or negative?
When you have a flat cord with three wires, there are three different types of wires with three different textures: a smooth (hot) one, a ribbed (neutral) one and a green (ground) wire. Although you can't see the ground wire when the plugs are on the cord, it is always between the hot and neutral wires.Which wire is negative smooth or ribbed?
Ribbed is the neutral (negative) side and smooth is the line (positive). AC is not "positive / negative" but rather "line / neutral" (there can be multiple 'line… see more. As one person indicated, if using traditional lamp wire, one side is ribbed and the other is smooth.Which wire on cord is hot?
Here's a rundown of electrical wires: The black wire is the "hot" wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the "neutral" wire, it takes any unused electricity and current and sends it back to the breaker panel.2 Brown Wires Which is Hot | Light Fixture Wiring
Is the ribbed wire positive?
Note that a ribbed wire is usually the negative wire on an extension cord. If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire.Does the ribbed wire go to brass or silver?
The large blade of the polarized plug is connected to a marked conductor in the cord (often ribbed). It goes the the silver screw that is connected to the shell of the socket. The small blade (no marking on cord) goes to the brass colored screw connected to the button in the bottom of the socket.Which wire is smooth?
Two-Wire Flat CordsThe hot wire is always smooth on the outside of the cord, while the neutral wire is ribbed on the outside. For flat cords with polarized plugs on the end, the larger prong (or terminal) is the neutral wire.
