Odd wiring colours

My fan heater packed up, so I checked the plug fuse. It was ok, but the power cord has two wires, a green insulated one to neutral and a white insulated one to live. Double insulated so no earth.



Where is that used? I guess the heater was from Lidl being branded 'Silvercrest'.



BTW, it's working again now - sticky tilt switch.


Nowhere that I know of, but rules are ignored in many far-flung places. The one thing it establishes is that the heater does not comply with UK safety rules. If it were mine I'd be taking a much closer look.

I wish they had some kind of tactile way to identify wires. Not just for us blind people but in very hard to reach places it would make identification much easier by feel. Brian

Not sure Lidl were selling in the UK before the standard flex colours came in.

White is used for the live side in US mains cables.

And red is used for earth in Japanese cables. I kid you not.

Nah, black is live, white is neutral IIRC.

Well, in nature green things are generally alive, and earth is usually brown. I suppose grey is fairly neutral.

Anyway, the cable in question has all the right markings and seems to be good quality.

It used to be in Germany, too - beofre harmonisation.

Indeed - think 'black death' and white is a neutral colour. Green is grass - which grows on the ground.

But it is very easy to differentiate by feel.

110V and up isn't a problem.

50-100V would need Ones pinkies dipped in salt solution.

Its probably safer not to. Do dymo do embossed labels you can read?

Dymo don't, but another manufacturer does

You sure about that? I thought US domestic supplies where 110 V biphase. ie 110 - 0 - 110. Normal appliances where connected between

0 and one of the phases. Big loads like washers connected between the phases and ran off 220 V and thus half the current for the same power @ 110 V.

Where? The USA's common system is 120V-0-120V with phase-phase being used for high load devices.

You're not confusing this with "yellow" building site transformers and tools are you?

He'd already owned up to the mistake nine hours berfore your post!

I reckon the colours should be blue for live "electric blue", magnolia for neutral (because it is) & brown for earth (because it is).

No the Earth is a blueish colour from space :-D

Anyway I think we should convert to Red white and Blue in honour of Brexit or of course let Boris decide once his PM. 8-{}

most live stuff on this planet is green. Or perhaps we should appease some political faction by permitting anything from cream to pink to brown to black.

Trouble is our colours are the same as the French, even the RAF insignia is based on the French one.

3 core and earth was red white and blue until the 14th edition.
