N & L stands for neutral and fiscal. Along with the power cord, you should have three cables. Neutral, Charge and Ground. If your wires are color coded for the United States, the black wire is Load or Warm, the white wire is neutral, and the green wire is grounded.
L, or Line, is a live conductor. Sometimes there is more than one. L1, L2 or even L3. The line is designed to carry electricity to the electrical load. N is neutral and leads the current back to where it comes from a box which is the main panel or fuse box.
know what each color of wire in the circuit is for
- The black wire is the hot wire that carries electricity from the electrical panel to the switch or light source.
- The white wire is the neutral conductor that takes the unused power and current and sends them back to the control panel.
Neutral (N) Earth or zero mean line and Bærestrøm line (L).
There are no positive or negative connections in AC, but line or phase (L) or (P) and neutral (N). They are important and one of the reasons is human safety.
Chapter 2 Color Codes
The meaning of (L) (L) stands for Love Heart (MSN)
The active (high potential) wire is brown (formerly red). The neutral conductor (low potential) is blue (previously black). The ground wire is green and yellow striped (previously it was only green).
There are two different names, L (Live) and N (Neutral) on the AC input. The L terminal must be connected to the non-grounded conductive part of the AC power supply and the N terminal must be connected to the grounded conductive part of the AC power supply to be approved by safety authorities.
Line (L preceding, live or in phase) Core / wire live in a typical home or low voltage installation with color coding. brown (before 2004: red). Neutral (N) Live core / wire in a typical low voltage or domestic installation, usually connected to ground voltage from the supplier, color coded.
The 3-wire cable changed from hot red to warm brown, from neutral blue to neutral gray, added from yellow to black with ground bar or green / yellow.
The old wire colors used in the UK for household appliances and appliances were previously three colors - black, red and green with yellow stripes. Black. The black electrical wire was the color of the neutral conductor.
A ground symbol (IEC 5017 symbol) indicates a ground terminal. It can be used for a potential-free reference point from which to measure current. It is also used for protection against electric shock.
The red electrical wire indicates the secondary power wires on a 220 volt circuit used in some types of switches and in the interconnection between smoke detectors connected to the electrical system. You can connect a red wire to another red wire or to a black wire.
The earth symbol is sadly used in many electronics and electrical engineering applications and often means different things to different people, so it can be a bit confusing for some beginners. For example, the earth symbol is also used as a regular base symbol or as a 0V reference.
Blue is negative and white is positive.
In 1999 it became clear that due to a new European standard for wire and cable colors, the UK needed to change the colors of the insulation insulation. As a result, it took the old British wire colors to replace the red power wire and a black neutral wire.
