Can you please advise where in BS7671 I find the colour coding for the outter sheath of cables carrying various voltages?
I believe the colours are 25V Violet 50V White 110V Yellow 230V Blue 400V Red Many thanks, John Jackson TMIET |

Those colours you refer to are the plug/socket colours as per BS EN 60309
Each voltage grouping has its own distinct colour coding for mating compatibility. regards ------------------------- "Take nothing but a picture, leave nothing but footprints!" ------------------------- "Oh!

Thanks but this section does not advise the industry known standard colours for the various power extension leads e.g. construction sites 110 volt is Yellow.
Any ideas? |

They do a plug where you can turn two of the pins to swop over phases, excelent idea.

We've found them on a lot of door control gear Spin, I guess it makes it simple for the door installers to change the rotation.
