Talk:Lighting Circuits Without an Earth
Metal fttings
There are also plenty of Class II metal fittings around that are perfectly compliant. These are no less safe on 2 core cable than on 3 core. I might not be a big fan of unearthed metal fittings, but they do comply. NT 15:19, 26 February 2011 (UTC)
I have updated the article. But don't call it 3 core:-) it makes you sound like a plumber --ARWadsworth 16:58, 26 February 2011 (UTC).
Well, its the term most diyers will understand. Same reason I avoid saying CPC, if someone needs to read a basic article they usually dont know what a CPC is. NT 23:03, 26 February 2011 (UTC)
There is nothing wrong with using the correct terminology. I specifically choose the article name to include the word earth NOT cpc to make it clear to non-electricians what the article was about, However the rest of the article should then use the word cpc where appropriate.--ARWadsworth 14:31, 27 February 2011 (UTC)
But there isn't really anything more correct about either term, earth wire or CPC. Both describe the same thing, one is widely understood, the other isn't. NT 15:43, 27 February 2011 (UTC)
Extensions
Actually extending 2 core circuits is quite safe as long as all accessories/luminaries are class II. Its just not regs compliant. NT 23:03, 26 February 2011 (UTC)
Right up until someone swaps a fitting. --ARWadsworth 14:31, 27 February 2011 (UTC)
Modern unearthed circuits
There's also much more modern earthless wiring here and there. I've seen some eyeopening wiring, I thought bellwire lighting circuits was bad enough till I saw assorted offcuts of 2 core flex twisted together and strung overhead, literally.
So I wonder if a small section suggesting checking the wiring type might be of use. Ie if its bellwire or speaker flex, its time to probe further. NT 23:03, 26 February 2011 (UTC)
Safety
Most of the safety section ought to be in a different place, eg Electrical Safety > Mainainance (or suggestions please) with a link to it from this article as it is applies to all older installations including ones that have an earth on the lighting circuits.--ARWadsworth 14:31, 27 February 2011 (UTC)
It could be. It seems to me to make sense though to include in the article a description of what the problem with earthless lighting is. Why not have the content in both places, it applies to both. NT 15:41, 27 February 2011 (UTC)
