Wire we know that it is divided into fire line, neutral line, ground line, in the wiring process, we must be clear it to avoid the wrong connection in the wiring process, bringing unnecessary trouble. The following Xiaobian will introduce you to the brown line is the fire line or the zero line.
The brown line is the live line or the zero line
Brown wire is a firewire, when the family uses wires, usually the two colors of red and brown, the neutral line will use blue, green and black wires of these colors, and the color of the ground line will use yellow and green two-color lines. If the three-phase electricity uses the wire, its fire line will use yellow, green, red this several colors.
How to distinguish the zero line from the live line
1. Distinguish by wire color
In order to facilitate installation and maintenance in the future, normal construction personnel will use the same color wire to represent the same loop, for example, the firewire loop will use red, the neutral line will use blue, or use black, and the ground line will usually use yellow and green wires.
2, through the test pen to distinguish
If you want to accurately distinguish the neutral line from the live line, use a test pen to distinguish. When detecting, one hand grasp the electric pen, the other finger to touch the metal sheet at the end of the electric pen, contact the exposed part of the wire, if the light indicates that it is the fire line, not the light indicates that it is the zero line.
3. Distinguish by multimeter
If the user has electrical expertise, it can be distinguished by a multimeter. When testing, the meter should be adjusted to the AC voltage gear, and then use the stylus of the multimeter to contact the exposed part of the wire, if the voltage value is less than 5 volts, it means that this is the neutral line, greater than 10 volts, it means that it is the fire line.
In SUMMARY: About whether the brown line is the fire line or the neutral line related content is introduced to this, the brown line is the fire line, when the family uses the wire, it usually uses the two colors of red and brown, the neutral line will use the blue, green and black of these colors of the wire, the color of the ground line will use the yellow and green two-color line, when wiring, be sure to separate them clearly to avoid the phenomenon of wrong connection. Cause unnecessary trouble.
