3 core twin and earths

[Thebeast27]

Came accross a re wire were the sparks first fixing had used 3 core cables down to every switch baffled as to why on 1 ways etc supervisor called it smart wiring ? Anyome else come accross this ?

 

[westward10]

It is for future smart switching which may require a neutral conductor.

The reg that asks this method be considered is 559.5.1.208

Providing a neutral to the switching point.

 

[Baddegg]

Future proofing man ?

 

[MJPD29]

Its 3 core and earth, twin and earth is 2 cables and earth. Hence twin.

Drives me bonkers too when people call it "3 core twin" - FFS twin means two!

sorry my mistake didnt realise i called it twin and earth in the title but no need to shaart abarrt it ?

 

[telectrix]

i install 3c/E to switch as standard these days, for the very samereason... future proof for smart switches.

I have worked with loads of sparks who call it 3 core twin

If it's a three core then it's not a twin is it? But technically it's a four core...

I call it triple

It's not four core, it's three core and earth. The earth is not counted as one of the cores, the exception to this being flex where we usually refer to a 3G flex as being three core.

Or to be more with the times, three core and CPC.

I was being pedantic... ??

Its not the earth its the cpc ? always used to kill me when my college tutor used to say that with an old croaky voice after 40 smokes a day

 

[Andy78]

It's only a cpc if connected as such. The ones that have been chopped out years ago aren't cpcs.

 

[Dave OCD]

Yes they are, in those situations they're just having a rest.

 

[Gavin John Hyde]

i wouldn't be surprised if in a future amendment that it becomes a regulation that light circuits be wired in 3 core and earth for this very reason, so that every point has a at minimum a perm live, neutral and cpc, and a switched live where required.

 

[Pete999]

I call it triple

Better still 3 core and Earth!!
