What does UL mean on wire?

Underwriters Laboratory (UL) is a third-party testing laboratory that certifies and tests products. UL assigns a different style number for each approved AWM construction and creates a style page that lists a few specifications, such as gauge size range, insulation material, temperature rating and voltage rating.

What colour wire is L and N?

Function	label	Color, common
Protective ground	PG	bare, green, or green-yellow
Neutral	N	white
Line, single phase	L	black or red (2nd hot)
Line, 3-phase	L1	black

Which wire is positive L or N?

A: N is neutral ( white wire) L is line or the hot side (black wire).

What are the 3 types of wires?

Three types of wire used are :

live wire ( Red colour)
neutral wire(Black colour)
earth wire (Green colour)

Which color wire is positive?

The positive current must be red. The negative current must be black. The ground wire, if present, must be white or grey.

Is black or white L or N?

Line (L) = black. Neutral (N) = white. Protective earth (PE) = green, green-yellow striped.

Is blue wire L or N?

The blue wire is known as the neutral wire, and its job is to take electricity away from an appliance, and back to the power supply.

Is L or N positive or negative?

Positive (labeled as “N”): White* Negative (labeled as “L-“): Black*

What is N and L in wiring?

There are two different name, L (Live) and N (Neutral) on the AC input terminal.

What are the 3 colored wires?

3-Phase Wire Color Codes

Phase 1 – Black wire.
Phase 2 – Red wire.
Phase 3 – Blue wire.
Neutral – White wire.
Ground – Green, Green with a Yellow Stripe, or Bare Wire.

How do I identify 3 wires?

The switch wiring for three-ways is normally Red, Black, and White. If the White is correctly used for neutral, the connected switching wires are Red and Black. The White (neutral) is often referred to as Common, but the colored wires are both used as Hot wires, alternately as the possible switch positions are made.

How do I identify a wire?

If you don't get a voltage reading the wire is neutral. If you get a reading the wire is hot you can

How do I tell which wire is positive?

On a standard wire used for things like speakers and amps, the silver strand is the negative wire and the copper-colored strand is the positive wire. These wires are often held together by a clear casing, but you can see through that (or look at the exposed wiring on the end).

What color is a live wire?

Wire	Colour
Live	Brown
Neutral	Blue
Earth	Yellow and Green

Which wire is usually positive?

The positive wire, also commonly called the hot wire, will typically be black in color. It is the source of the electricity. The electrical current travels from the outlet or other power source on the positive wire, so if it is plugged in anywhere, it should be considered a live (and dangerous) wire.

Which is L or N?

The N & L stand for Neutral and Load. With your AC line in you should have three wires. Neutral, Load, and Ground. If your wires are color coded for the US then the black wire is Load or Hot, the white wire is Neutral, and the green wire is Ground.

Is black L or R?

Following the logic from the DAC (black is L and red is R) I hooked my head amp up the same way and it was wrong (right was left and left was right in audio/games) so I swapped them on the back of the head amp and everything worked correctly.

Which wire is white and black?

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.

Is L1 live or neutral?

The faceplate of a single, one-way switch has two terminals: "L1" is the terminal to which the neutral core wire is attached - the blue wire (traditionally black, before the change). "COM" or "Common" is the terminal to which the live core wire is attached - this is the brown wire (formerly red).
