In North America the neutral has to be identified as such. On a lamp cord the ribbed insulation side is the identification of the neutral wire. The "hot" conductor of the lamp cord is the smooth insulation.
No. Screw material is no safe indicator because they would be too easy to swap round.

Is hot wire on the extension cord ribbed or smooth?
The hot wire on an extension cord is typically smooth. The ribbed wire is usually the neutral wire. Make sure to check the cord carefully to confirm the proper identification of wires before handling or using it.
Do yo connect black wire to smooth wire or ribbed?
Connect the black wire to the smooth wire. The ribbed wire is the identifier for the neutral wire which is connected to the shell of the lamp holder. The smooth wire connects to the center pin in the lamp holder. Using this configuration the hot wire is kept away from your fingers as far as possible when changing out the light bulb.
What color is polarized wire?
Polarized wire typically has one wire with a ribbed or textured surface to indicate polarity, while the other wire is smooth. The colors of the wire insulation itself can vary, but the ribbed wire is commonly white or silver, while the smooth wire is usually black.
Is ribbed wire hot?
Ribbed wire typically refers to a type of reinforcement wire used in concrete construction and is not typically hot. However, if an electrical current is passing through the wire or it is being used in a high-temperature environment, then it could become hot.
Is the ribbed wire on a extension cord the black?
The ribbed wire on an extension cord is typically the neutral wire. The black wire is usually the hot wire. It's important to check the manufacturer's instructions or consult a professional if you are unsure.
How is the non-ridged smooth-sided parallel wire attached to a chandelier light fixture coded to determine which wire is hot and should be connected to the black?
The ribbed sheathing always denotes the neutral conductor and should be connected to the neutral incoming power conductor (usually white). The non-ribbed sheathing is the hot conductor and should be connected to the hot incoming power conductor (generally black). It will work if wired backward (reverse polarity), but if the appliance is polarized, you should wire it accordingly. For example, a light socket is generally polarized to make the ribbed socket part (which human hands will likely come in contact with) neutral. Wiring with reverse polarity would make this socket hot (not safe).
Do the ribs on one side of a wire mean neutral or hot?
Standard 115 extension cords have three wires but sometimes the ground is the only wire that is color coded. If you cut off the plug, you can lose a sense of which wire is NEUTRAL (white) and which is HOT (black). Its easy if you THINK. Look at the plug as and a receptacle as if you were going to push it in. The ground wire (green) is on the bottom. The ribbed side is on the left of the plug. If you look at a receptacle, you will see that side is NEUTRAL. The smooth wire side is on the right of the plug and would connect to the BLACK side of the receptacle. Got it? Most 3-wire cords use color coding. Most 2-wire cords use the "ribbed" method. The RIBBED side is supposed to be the "identified wire" which is the neutral. Be careful with thinking "right" or "left" because some 3-wire receptacles are installed horizontally or with the ground up. Further, don't assume the ribbed side is neutral on an existing installation unless you test and confirm it.
Electrical wire with clear insulation which wire is hot?
In standard electrical wiring, the black wire is typically the "hot" wire carrying the current, while the white wire is the neutral wire returning the current. If the wire has clear insulation, it may be difficult to distinguish between the two visually. It is best to use a voltage tester to determine which wire is hot.
What are the differences between ribbed wire in black and white colors?
The main difference between ribbed wire in black and white colors is their appearance. Black ribbed wire is darker in color, while white ribbed wire is lighter. This color variation can affect how the wire blends in with its surroundings and may impact visibility in different environments.
Is the ribbed wire positive or negative in terms of its impact on the electrical circuit?
The ribbed wire is negative in terms of its impact on the electrical circuit.
What are the differences between ribbed wire in black and white?
The main difference between ribbed wire in black and white is the color. Black ribbed wire is typically used for outdoor applications as it is more resistant to UV rays and weathering. White ribbed wire is often used for indoor applications and is more visible in low-light conditions.
What are the differences between ribbed wire in white and black colors?
The main difference between ribbed wire in white and black colors is the color itself. The ribbed wire in white color is more visible and stands out against most backgrounds, while the black ribbed wire is less noticeable and blends in with dark surfaces. This can affect the aesthetics and visibility of the wire in different environments.
