  When we used to watch blockbusters of police and gangsters, this scene often appeared: "The gangster installed a bomb in the building or somewhere, and our protagonist was ordered to defuse the bomb. After demolition and demolition, the bomb is about to explode, which often appears at this time. Two choices, choose to cut the red line or the blue line, this is a completely random choice, but the protagonist always gets it right." However, in reality, we may not have such good luck, so the color of each wire has a special meaning. Next, let the power adapter manufacturer reveal the secret of the wire color for everyone.

  Generally, there are five different colors of wires in the electric box, which correspond to:

  Yellow: L1 phase in a three-phase circuit, namely A phase; Green: L2 phase in a three-phase circuit, namely B phase

  Red: L3 phase in the three-phase circuit, namely C phase; blue: working neutral line N; yellow-green: protection neutral line PE

  according to national standards

  Phase conductor color: black, brown, red, orange, yellow, green, purple, gray, white, pink, turquoise;

  Neutral line suggested color: blue;

  Suggested color of grounding wire: yellow-green stripes (it is stipulated that this color cannot be used as other conductor colors)

  So why distinguish the colors of the wires?

  The national standard requires different cables to use different colors, mainly to correctly distinguish the phase wire, neutral wire and protective ground wire in the wire to prevent erroneous operation. In general electric power construction units, although there are strict operating specifications, in the real construction, there will always be people who make wiring errors due to carelessness or misoperation, resulting in serious power accidents. By sorting the wires by color, more operational errors can be reduced. Today's sharing of power adapter manufacturers is here, safe use of electricity, rest assured charging,
