Wiring Color Codes

Fig. 6 – Wiring Color Codes in Europe (IEC) for DC Supply. Wiring Color Codes in Canada. The Canadian Electrical Code (CEC) regulates electrical wiring color coding in Canada. The AC power cable color code is nearly similar to the code used in the USA except exclusion of bare copper from ground wire.

The older color codes in the table reflect the previous style which did not account for proper phase rotation. The protective ground wire (listed as green-yellow) is green with yellow stripe. Click to expand infographic . IEC (most of Europe) AC power circuit wiring color codes

IEC Color Code for most of the European Union (Including UK from 2004) Most of the European Countries follow the International Electro-technical Commission’s electrical wiring color code. United Kingdom had its own color code until 2004. But from March, 2004, the UK started following the IEC color code.

International wire color codes are often specified by law depending on your location, though most rely on common practice, below we cover Europe and Canada. Wire Color Codes for Europe (IEC) The International Electrotechnical Commission (or IEC) has established a wire color code for most European countries for AC “branch” circuits.

Types of Wire Color Codes There are quite a few different wire color code standards in place, so it is important to understand which one to follow in which situation. The standards used will vary based on what country the wiring is being done in, and the type electricity it is for, and other factors.

RE: european wiring codes ccaserta (Specifier/Regulator) 22 Feb 02 14:39 Sorry for the late reply if your still interested, there is a color code chart in EN 60204-1 Electrical requirements for machinery.

European (IEC) Wire Color Codes Most European countries follow a wire color code established by the International Electrotechnical Commission (IEC) for AC branch circuits. This standard was originally published as IEC 60446, but was merged into IEC 60445 in 2010.

Wiring Regulations saw a change to harmonise the UK wiring colours with European cable colours for consistency and to avoid confusion. The old cable plug colour codes did not account for proper phase rotation, therefore most of Europe now abides by IEC (International Electrotechnical Commission) wiring colour codes for AC circuits.

The harmonised standards for installation wiring apply to all EU countries. In my opinion they are pretty vague on control wiring, leaving it largely up to customer preference. I don't know of any published standard for control panel wiring colours, but our site standard is fairly typical for the UK:

Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure.. Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the ...
