The wire on a lamp cord that is known as the hot wire is typically the black wire.
The wire that is hot on a lamp cord is typically the one that is black or red in color.
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.
The wire that is hot on an extension cord is typically the black wire.
The type of wire you are looking for is called lamp cord. It comes in different colours usually to match the fixture. Fixtures hanging from chains use a clear insulation so as to blend in with the fixture chain colour. Remember that the smooth wire of the lamp cord connects to the hot wire and the ribbed wire on the lamp cord connects to the neutral wire in the ceiling junction box.
The hot wire's cover is smooth and connected to what I call the "button" at the bottom of the socket. The neutral wire's cover has ridges and is connected to the screw shell of the socket.
If you are referring to lamp cord type wire where both wires are brown then yes, connect the wire with the groves to the white neutral and the smooth wire to the black hot wire.
The lamp wire is hot because electrical current flowing through it encounters resistance, which causes the wire to heat up.
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.
When checking for electrical connections, the wire that is hot is typically the black wire.
The best way to find the neutral wire on any lamp is to ring the wire out. Before there were polarized plugs and receptacles a lamp could be plugged in either way. All new lamps have polarized plugs where the neutral is connected to the shell of the lamp holder and the "hot" wire is connected to the center pin deep in the lamp socket. Back to your goose neck lamp, you will need a meter that reads resistance and use it as a continuity meter. With the lamp unplugged and the lamp's switch in the off position connect one lead of the meter to the shell of the lamp holder. Take the other lead and touch it to one of the plug cap blades. If the meter gives a reading it is that blade that is the neutral wire. If there is no reading then that blade is considered the "hot" wire. If you are changing the plug (cap) out for a new one connect the newly established neutral wire to the silver coloured screw and the newly established "hot" wire to the gold coloured screw. Now when ever and where ever the lamp is plugged into a voltage source the polarity will be correct and the lamp will be much safer to use.
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.
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.
