Black, red, and blue are used for 208 VAC three-phase; brown, orange and yellow are used for 480 VAC. Single Phase, Line (Hot) – Black or Red 2. In some uncommon situations, one phase will have a higher voltage than the others. A 3 phase panel wiring is A, B, C – left to right- and top to bottom. Siemens SW3054B3200 200-Amp Outdoor Main Breaker 30 Space, 54 Circuit 3-Phase Load Center, COLOR. The blue colours in those images (the originals in the Wikipedia article, and the images above) are rather poor, particularly the dark blue. The standard colours in fixed wiring were harmonized in 2004 with the regulations in other European countries and the international IEC 60446 standard. Australian electricians will probably be familiar with it, and it is "legal" in Australia. In commercial 120/208 volt electrical systems, there are three phases – A, B, and C. Each phase is one of three colors – black, red, or blue. In Canada, wire color coding standards are set by the Canadian Electric Code (CEC). European codes usually require individual screw terminals for joining wires (not wirenuts). A number of colors are prohibited from being used for phase wires. So I would say that if your product may be dual marketed into EU countries, you should consider using the EU color codes. I think there is some social statement in this. Circuits are labeled with the odds on the left and the evens on the right. When using the rule of six you will reference the first six circuits, their phase and color. while EU uses Smirf color for neutral. Maybe the ones with the little "1" by them are the ones for three phase, black red and yellow. c) 3-phase ac — 1 red (phase A), 1 black (phase B), 1 blue (phase C), and 1 white* (where a. neutral is required).

For three phase wiring, our standard colours are: Phases: Red, White, (dark) Blue Neutral: Black Earth: Green/Yellow Ground - Ground wiring can be green or green with a yellow stripe. Conductors of a three-phase system are usually identified by a color code, to allow for balanced loading and to assure the correct phase rotation for motors. For a single-phase supply – Red or brown is used for line and black or sky blue is used for neutral. The wiring may also come with no colour code at all. For example, a two pole three phase motor has 6 nests, 3 coils per nest, and 6 leads. The following requirements on wire color codes apply in Canada: 1. It then starts over with the phases. In that standard, it is recommended that three-phase colors used in a building be red/white/dark blue. British Standard BS 7671:2001 Amendment No 2:2004 adopted the IEC 60446 colours for fixed wiring in the United Kingdom , with the extension that grey can also be used for line conductors, such that three colours are available for three-phase installations. 4) Where the midpoint of one phase of a 4-wire delta-connected secondary is grounded to supply. Phase 2 is similar to phase 1, V head start ----- Y end head. Again, the bi-colour green-and-yellow marking of protective conductors will remain unchanged. But since one of the suggested phase wire colors is dark blue, it seems that black is a better choice for neutral. 1 1 1 rg 17.76 17.76 384 559.68 re f BT 36 563.04 TD 0.349 0.349 0.349 rg /F0 10.08 Tf -0.047 Tc 0 Tw (Document) Tj 43.2 0 TD 0 Tc -0.1181 Tw ( ) Tj 34.8 0 TD 0.0121 Tc 0 Tw (Technical) Tj 38.88 0 TD 0 Tc -0.1181 Tw ( ) Tj 109.92 0 TD ( ) Tj -226.8 -12 TD 0.0973 Tc 0 Tw (Type) Tj 20.16 0 TD 0 Tc -0.1181 Tw ( ) Tj 57.84 0 TD -0.0287 Tc 0.0306 Tw (Mains Wiring Colours) Tj 89.04 0 TD 0 Tc -0.1181 Tw ( ) Tj -167.04 -13.44 TD 0 0 0 rg /F1 11.04 Tf -0.095 Tw ( ) Tj 0 -25.44 TD ( ) Tj ET q 134.4 17.76 150.48 10.32 re h W n BT 134.4 19.44 TD 0.1294 0.3451 0.4078 rg /F1 9.12 Tf -0.0498 Tc 0.0287 Tw (www.netvue.co.uk +44 \(0\)20 8567 2201) Tj ET Q q 284.88 17.76 9.6 16.8 re h W n BT 284.88 19.44 TD 0.9843 0.4 0.1333 rg /F2 15.12 Tf -0.0422 Tw ( ) Tj ET Q q 112.56 0 0 -40.8 271.68 577.44 cm /im1 Do endstream endobj 15 0 obj 851 endobj 12 0 obj << /Type /XObject /Subtype /Image /Name /im1 /Filter /DCTDecode /Width 150 /Height 54 /BitsPerComponent 8 /ColorSpace /DeviceRGB /Length 13 0 R >> stream Relevant citations From AS3000:2007+A2 Wiring Rules: It seems these are the new colour standards for equipment, based on the most recent National Electrical Standards as of 2010 thru 2017.
