The white line on a black wire typically indicates that the wire is a hot wire that has been re-identified for use as a different phase or conductor in a circuit, often in situations where the wiring color code needs to be modified for clarity or safety. In electrical wiring, black is usually used for hot wires, while white is reserved for neutral wires. The marking helps ensure proper identification and prevents confusion during installation or maintenance. Always consult local electrical codes and standards for specific guidance.
Black is the hot side of the line, white the neutral side, green (or rarely bare) wire is the ground.
Some light fixtures do not have a grounding wire. In such cases the two wire going to the light may both be black. You can connect black supply to either black light wire and white supply to the other black wire.
If both wires are black, the one that connects to your white wire is the one that should have little writing on it. Black to the plain black wire, white to the wire with writing.
Wall receptacles are wired in parallel. black to black, white to white, ground to ground.
the black wire is the hot wire
House wire is "line" Black & White house goes to Black & White of Timer; the "load" (e.g. Pond Pump, etc.) is connected to the Red & White. Specifically, put all 3 whites together (nut or terminal); House (source)(line) Black to Timer Black; and "load" Black to Timer Red. The Red wire is the "Timed" (switched) hot wire.
The Load wire is always hot (black or red wire) and the Line wire is the one that returns to your fusebox (usually white). Answer above is absolutely wrong written by someone who does not know electricity and will get you electrocuted. The white wire is your neutral wire. The black or red coming from the electrical panel is the line wire. the black or red wire going to the next outlet or light fixture is your load wire. in some cases a white wire will be a line or load and should be indicated with black tape on it denoting it is not a neutral. quick recap is Line = power in, load = power out.
the thermostat has a black(line) wire to it, and a red wire going to it. the red wire then connects to the neutral wire. the black and red are like a leg switch.
Black is the hot side of the line, white the neutral side, green (or rarely bare) wire is the ground.
The white wire is typically neutral, the black wire is usually hot or live, the red wire may be a secondary live wire or used for a separate function, and the bare wire is typically the ground wire for safety purposes in an electrical circuit.
It will be the wire without the black line on it. Usualy the black line on a solid color will mean negative (-)
Means it's positive
Connect them in parallel. The black wire from the ballast to the black line wire. The white wire from the ballast to the line neutral. Connect the ground wire to the ground screw which is located in the body of the fixture. Grounding of the fixtures is essential.
The black wire is typically hot, while the white wire is neutral.
In a standard electrical wiring setup, the black wire is typically the hot wire, while the white wire is the neutral wire.
The red wire typically goes to the black wire.
The red wire typically connects to the black wire.
