european wiring codes

Hi,

I need a conversion chart for U.S.A to European wiring codes. Does anyone know where I can get this type of information? Thanks

Sorry for the late reply if your still interested, there is a color code chart in EN 60204-1 Electrical requirements for machinery. I would stay away from color codes if possible. It's not necessary to use color code for Europe when you get into three phase wiring. Numerical Identification is your best bet. This will keep you from trying to control the different color variations you get from your component vendors. There is no way to control what they supply you and before you know it your color code has been blown out of the water.

Identify your conductors using numbers at both ends and document the information for your service persons. Christopher Caserta

There is no such standard as such. The wiring standards in Europe differ quite widely through the countries although they are working towards harmonisation. It depends what you are looking for and which country you plan to work in

Graeme W, actually the color code is called out in EN 60204-1. EN means European Normative (EU Hanrmonized standard) it has been accepted by CENLEC and the 15 EU countries. I beleive IEC 60204-1 became an EN in 1999. IEC 60204-1 has been the accepted standard to use for manufactures CE Marking and European Licenses from the Notified Bodies even before 1995 when the Machinery Directive became mandatory. Although at the time it was not an EN standard it was still accepted and called out by the Machinery Directive as the standard to use for the Electrical requirements for Machinery for the EU. In EN 60204-1 it clearly states the color code to use I beleive in clause 14.2 "Identification of Conductors". Therfore I think it is safe to say there is a harmonised color code. Christopher Caserta

Christopher, I understand what you mean, but it depends where you are working. I have spent time working in Latvia, Bulgaria, Macedonia, Armenia etc. etc. While most are technically in Europe I find that they all use different standards. I am not sure if these countries are harmonising but for example in Macedonia they use green/yellow as phase conductor on distribution systems. When I am trying to carry out design installation work it is pretty difficult to convince the local electrical authorities when I apply UK wiring standards.

Good Point, I was speeking only of the EU and ot all of Europe. Christopher Caserta

HI I am trying to tie an apparent European motot to US standards.I have leads from the motor that are brown, blue, and yellow/green. Can any one help...what goes with our black, white and green?
Thanks, Dick

 

[ccaserta]

Hi juddsy European Brown is Line, Light Blue is neutral and Yellow/Green is Ground. Normally US Black is line, White is neutral and Green is gound. I suggest that you verify the US colors with the installation instructions. Christopher Caserta

hi,

I need a table of EU and American standard electrical color codes. Any website?

I am just reposting from other newsgroup please verify before using
*************
new colour code.
(CENELEC standard HD 308 S2:2001)

L1 - Brown
L2 - Black
L3 - Grey

For cables with earth conductor the code is:

5 - conductor
Green/Yellow, Blue, Brown, Black, Grey

4 - conductor
Green/Yellow, Brown, Black, Grey

3 - conductor
Green/Yellow, Blue, Brown

For cables without earth conductor it is:

5 - conductor
Blue, Brown, Black, Grey, Black

4 - conductor
Blue, Brown, Black, Grey

3 - conductor
Brown, Black, Grey

2 - conductor
Blue, Brown

 

We make heaters and controls for process and semiconductor industries. UL says don't use 60335 (not industrial) or 60204(for machines). TUV CEd a couple heaters used 60519(heater installations) but refernced both 60335 and 60204.

Any body got a clue what to use?

I Agree with TUV, it sounds like your customer is the guy who incorporates your component into their final design. Although you should design your product to a standard like EN 61010/A2 for process and control, it only makes sense to make sure your color code will agree with the customers end standard. By the way we're talking about color codes, it shouldn't matter what standard is referenced. The only thing EN 60204 allows you to do over and above the normal color code is to apply numerical or alphanumerical identification.

If UL has a problem with this, ask the engineer what standard he recommends. If he dosent give you an answer then call his boss and ask for a new engineer. He shouldn't have a problem with which standard your using for color codes. The only issue may be crossing US requirements with the EU. Christopher Caserta

I need a copy of EN60204, where's the best place to get one without paying a fortune?

Thanks

I am looking for color coding for a Swiss piece of equipment. The wiring on the unit is Dark Blue, Black, Green/Yellow (Ground?). How does this relate to the US wiring colors? Also this piece is 230 V 10Amp unit but the main power cable seems to be 14 gauge. This looks a little thin. Is there a code covering wire gauge?

Thanks,
