Plant Automation/Controls / wire color code
What you are asking for is covered in NFPA 79.
你真的应该有一个副本，如果你是布线实业控制面板或机器。
You should really have a copy if you are wiring industial control panels or machinery.
颜色编码是为NEC如下。
The color coding is as follows for NEC.
请注意，符合IEC接线是不同的，是你在棕色，蓝色，黑色，白色传感器线路找到。
Note that IEC wiring is different and is what you find on the brown, blue, black, white sensor wires.
符合NFPA 79工业机械电气标准 - 接线方法与实践： NFPA 79 Electrical Standard for Industrial Machinery - Wiring Methods and Practices:
绿色或绿黄色与一个或多个叶柄 - isulated设备接地conducor。 Green or Green with one or more Yellow Stipes - isulated equipment grounding conducor. 符合IEC要求双色导线。 IEC requires the Bi-Color conductor.
黑色 - 线电压 - EA. 120VAC, 230, 480.
红色 - 在比线电压，从四百八十〇分之二百三十○伏主变压器120伏交流电控制交流少导体。
Red - AC conductors at less than line voltage, 120vac from a 230/480 vac primary control transformer.
白色或灰色自然 - 电路接地导体。
White or Natural Gray - Grounded circuit conductor.
从接地变压器中性导体。
The grounded neutral conductor from the transformer. （符合IEC采用淡蓝色。） (IEC uses light blue.)
蓝色 - 不接地导体直流电流进行，对于我们大家一般都24V直流控制，所有的信号线和不属于特区的COM。
Blue - Ungrounded DC current carrying conductors, for us controls guys usually 24vdc, and ALL signal wires that are not DC Com.
迪的，DO的，大赦国际的，敖的，脉冲直流，任何载流导体直流。
DI's, DO's, AI's, AO's, pulsed DC, any DC current carrying conductor.
白蓝条纹 - 接地电流承载直流电路导线。
White with Blue Stripe - Grounded current carrying DC circuit conductors.
直流接地常见。
DC grounded Common.
这是不完全说明该做些什么一浮直流常见，但是，如果直流常见的是毫无根据，它是一个载流导体直流，所以我总是用上面的接地直流共接线蓝。
It is not exactly stated what to do for an ungrounded DC common, however, if the DC common is ungrounded, it is a DC current carrying conductor, so I always use Blue as above for ungrounded DC common wiring.
当我命令白/蓝条线，我指定50％的安全条纹覆盖。
When I order the White/Blue stripe wire, I specify 50% stripe coverage for safety.
我认为，这使得更多的白色面板中的中性线distingushable。
I think that this makes it more distingushable from the white neutral wire in the panel.
有没有多宽的条纹需要的代码。
There is no code for how wide the stripe needs to be.
黄色 - 不接地控制电路，通电时保持手段是主要的切断电
源关闭导体。
Yellow - Ungrounded control circuit conductors that remain energized when the main disconnecting means is OFF.
售票员必须在整个在面板和外部现场布线，包括电路黄色。
The conductor needs to be Yellow throughout the entire circuit including in the panel and in the external field wiring. （符合IEC使用该接线橙色。） (IEC uses orange for this wiring.)
例外情况： Exceptions:
在这里您可以运行multiconducor电缆。
Where you may run multiconducor cable.
从PLC电针的接线端子。
ea from the PLC to the terminal blocks.
对个别设备的内部配线的购买完全有线。
Internal wiring on individual devices are purchased completely wired.
凡不保温所需的颜色电针高温，耐化学品性接线可用。
Where the insulation is not available in the required colors ea High Temp, Chemical resistant wiring.
导线需要加贴标签，并在每个终端上的对应原理图和接线端子鉴定。
Conductors need to be labeled at each termination and correspond with the identification on the schematics and terminal block.
导线需要为电源电路14awg。
Conductors need to be 14awg for power circuits.
16awg照明和控制电路的机器上或在跑道。
16awg lighting and control circuits on a machine or in a raceway.
在护套多芯电缆18awg是允许的。
In a jacketed multi-conductor cable 18awg is permitted.
控制电路18awg在一个外壳或操作员站。
18awg for control circuits within an enclosure or operator station.
24awg电子可编程控制I / O和水道静态控制导线，30 AWG的多芯电缆护套在大会或更大。
24awg Electronic programmable control I/O and static control conductors in raceways, 30 awg or larger in a jacketed multiconductor cable assembly.
26awg控制机箱内导体。
26awg for conductors within control enclosures.
使你的特设工作组的选择是由载流量表规定：
The stipulation of your choice of awg is by ampacity table:
24awg - 2A
22awg - 3A
20awg - 5A
18awg - 7A
16awg - 10A
14awg - 15A条，20A条在控制机柜
14awg - 15A, 20A in a control enclosure
12awg - 20A条，第25A条在控制机柜
12awg - 20A, 25A in a control enclosure
10awg - 30A条，40A条在控制机柜
10awg - 30A, 40A in a control enclosure
希望这会有所帮助..
Hope this helps..
