Dc power cable which is positive. Compared to domestic ac power plugs and sockets dc connectors have many more standard types that are not interchangeable the dimensions and arrangement of dc connectors can be chosen to prevent accidental interconnection of incompatible sources and loads. Dc power circuit wiring color codes. If your multimeter has any reading that s a positive number like 9 2 for example the leads are connected correctly. A dc connector or dc plug for one common type of connector is an electrical connector for supplying direct current dc power.

Dc power installations for example solar power and computer data centers use color coding which follows the ac standards. The system used is different. This means that the wire hooked to the red lead is positive and the wire hooked to the black lead is negative. The other wire is negative and can go to the negative terminal of the battery or otherwise grounded to anything metal on the car.

Note that the wire on the red lead is positive if the reading is positive. The iec color standard for dc power cables is listed in table below adapted from table 2 cook. Just a quick tutorial video. The dc cable has the following characteristics compared with the ac cable.

Iec dc power circuit wiring color codes. Color coding for dc power circuit wiring depends on the function and the location country of the wiring. That wire is your positive. Many computer systems solar power systems electronics automotive applications and telecommunications systems run off of dc direct current power supply.

Compared with the ac cable the power loss during the transmission of the dc cable is small. Words alone are not a marking. There will be ribs lines dashes or some form of clear marking.
