Colour-code according to IEC Colour of. The following IEC DC wiring color codes are used for Two-Wire Grounded, Two-Wire ungrounded and Three Wire grounded DC power systems. These are listed in Table below. In Partnership with Omron Electronic Components. The IEC color standard for DC power cables is listed in Table below, adapted from Table 2, Cook. BLUE - DC CONTROL CIRCUITS (+24V DC) That would be the norm, although most copanies have 'their' standard colours, that combination I would say is the most common. The colors adopted as local practice are shown in Table below. Published under the terms and conditions of the, Drones Dispatched to Measure the Intensity of Hurricane Matthew, Op-Amps as Active Band-Pass and Active Band-Reject Filters, Positive (of a negative grounded) circuit, Negative (of a negative grounded) circuit, Positive (of a positive grounded) circuit, Negative (of a positive grounded) circuit. US, AC:The US National Electrical Code only mandates white (or grey) for the neutral power conductor and bare copper, green, or green with yellow stripe for the protective ground. See Table below. But from March, 2004, the UK started following the IEC color code. Three-phase lines are red, black, and blue. UK, AC: The United Kingdom now follows the IEC AC wiring color codes. The standard has been withdrawn; the fourth edition (IEC ) was 2: adopted the IEC colours for fixed wiring in the United Kingdom [1]. Hot (active) wires may be any other colors except these. This standard was originally published as IEC , but was merged into IEC. Table below lists these along with the obsolete domestic color codes. For example, what would the colors be for these voltage levels: 125VDC 48VDC 24VDC 12VDC I'll admit that the issue of wire colors as stated in the IEC are a bit confusing to me. For adding new colored wiring to existing old colored wiring see Cook. In the old IEC color code, all the lines in three phase supply are either brown or black.

Learn what each of the various colors mean in wire color coding standards. In that case, local custom dictates the “optional” wire colors. Personally do not like that. In some jurisdictions all wire colors are specified in legal documents. Create one now. IEC, DC: DC power installations, for example, solar power and computer data centers, use color coding which follows the AC standards.

Black, red, and blue are used for 208 VAC three-phase; brown, orange and yellow are used for 480 VAC. In that case, local custom dictates the “optional” wire colors. International conductor color coding per EN 60445 Section 6 and IEC 60227-1 Section 4.1.2 North American conductor color coding per UL 62 and CSA C22.2 No. Usage of the ungrounded system is discouraged for safety. In principle any other colors except these may be used for the power conductors. 49 Japanese conductor color coding per JIS C 3306 Note on Flexible Cable: Color codes listed on this chart are typical for what is seen in flexible cable. The older color codes in the table reflect the previous style which did not account for proper phase rotation. IEC, AC: Most of Europe abides by IEC (International Electrotechnical Commission) wiring color codes for AC branch circuits. Canada: Canadian wiring is governed by the CEC (Canadian Electric Code).
