What are the red, blue, and green wires? Want to learn under the thank you Oh
Others asked the red, blue, green and black four lines, and now some people back some shit. General yellow red green for the ABC phase line (FireWire), blue for the N line (zero line), black for the PE ground (yellow and green color line), no, do not casually misleading.
(L1), green B phase (L2), red C phase (L3), black for the zero line (N), yellow and green double color line for the Ground protection line. If it is pure three-phase load of three-phase electrical lines, black wire can be used as a ground protection line. International standard is: red A phase (L1), yellow B phase (L2), green (or basket) color C phase (L3), black for the zero line (N), yellow and green two-color line for the ground protection line. Where the three-phase plug or socket should be four-core, plug or socket terminals have obvious mark, usually the middle of the thick, big point of the terminal is connected to the protection line, and then from left to right respectively Then A, B, C phase line. If your load is three-phase four-wire system, then the middle of the middle thick, big point of the terminal connected to the zero line.
Yellow A phase (L1), green B phase (L2), red C phase (L3), black is zero line (N)
If it is the wire then remove the black line is the ground, the other three are FireWire.
