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)
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)
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)
