ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Square Switch Plates?

Aussie,
Good on ya mate!.
Yeah I found it,
What I failed to mention was the fact that these older type switches had thier own boxes.
Usually they'd be screwed to a dwang(nogging) on it's edge through the back of the box.
If you wanted to change it, you'd have to open the wall around the box, to take the dwang out.
You can't get a standard flushbox in there with a dwang in the way.
Great to have experience in these sorts of things though.

All part of the new scheme of things. Previously regular cables were:

2-core: red, black
3-core: red, yellow, blue
4-core: red, yellow, blue, black.

(Substitute white for yellow before 1965.)

With the the new color code the cores have just been replaced one-for-one, so:

2-core: brown, blue
3-core: brown, black, gray
4-core: brown, black, gray, blue.



There has already been one report on the IEE website of someone getting confused between the old and new colors and cross-connecting a phase and neutral on a 3-ph system.


I don't recall ever seeing anything like that here.
