Does it matter which wire goes on a lamp socket?

Quote from Youtube video: These sockets are just crimped in there so you just wiggle it a little bit in a little pull up the top cap comes off.
What happens if you wire a lamp wrong?
But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.
When rewiring a lamp which wire is hot?
If your cord is clear, the copper-colored wire is hot, and the silver wire is neutral. If the cord is white, brown, or black, the wire with the smooth surface is hot, and the one with ribs is neutral.
How do I know which wire is neutral on a lamp?
You can identify the neutral side of the wire just by looking for markings on one of the wires. The most common identifier is ribbing in the rubber insulation all along one edge, but it can also be a white wire or a white stripe (photo below).
Do old lamps need to be rewired?
Depending on the age of the lamp, you may have to bring in new wires too. This is because different bulbs may have different wiring systems and if the existing system does not perfectly fit in then you will have to rewire your antique lamp as well. Electrical faults do and can occur at any given time.

Which wire is positive and negative on a lamp?
When you’re hanging a chandelier or any other ceiling light, first find the 3 wires coming out of the hole in the ceiling where the light will go. Recognize that the black wire is the positive one, the white wire is the negative one, and the green wire is the ground.
Which side of a lamp cord is positive and which is negative?
Identify the neutral wire: How to Tell Negative and Positive Wire. You can identify the neutral side of the wire just by looking for markings on one of the wires. The most common identifier is ribbing in the rubber insulation all along one edge, but it can also be a white wire or a white stripe (photo below).
How can you tell which wire is hot and neutral on a lamp?
Quote from the video:
Quote from Youtube video: And one blade is wide the narrow blade is hot and the wide blade is neutral the insulation on the hot wire is smooth the insulation on the neutral wire is ripped.
How do you tell which wire is positive and negative on a light fixture?
Touch one probe of a voltmeter to the top of the bulb socket sleeve (not the small metal tab inside the socket) and the other probe to the circuit ground wire and have a helper turn on the power at the service panel. If the meter indicates positive voltage, the wires are reversed.
What happens if you wire live and neutral wrong in a light?
There would be a shock hazard, and some devices might not work correctly. Depending on where exactly the wires are flipped, ground fault detecting circuit breakers may become ineffective. All around, this is a bad idea.
What happens if you mix up hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.
Which wire is hot when both are black?
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.
Which is live black or white?
US AC power circuit wiring color codes
See Table below. The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.
How do you tell which wire is hot and which is load?
Quote from the video:
Quote from Youtube video: And then remember gold goes to the hot. Side so the gold terminal. And that's on my line. Set and then silver goes to neutral or the white wire.
Why are there two black wires?
Black means hot, white signifies neutral, and green indicates ground. However, if you need to rewire a light switch or a plug socket, you may occasionally come across two black wires. It’s essential that you determine which black wire is hot before proceeding.
What are the 4 wires in a light fixture?
A four-wire electrical line has a red hot wire, a black hot wire, a white common wire and a ground wire. A two-wire line is usually a black hot wire and a white common wire. The ground may be there, but it may not be connected.
