Messed up but can it still be done

[S&HB]

Hi I have just done first fix wiring in a extension and wanted to put in a two way lighting circuit, the walls have now been plastered and I have noticed that I have used an old 2c + bare earth cable between the two switches . can 2 way switching still be done.
I was thinking about using the earth core as a strap wire sleeved brown both ends and fitting a 6A RCBO
as protection....

Thanks
Steve

Welcome to the forum S&HB

Your profile doesn't show any electrical qualifications or experience and only shows an ONC in Engineering which could be one of several areas... that said and the level of question you are asking then the thread may be relocated to DIY section when admin is next on line, this will not effect any posts already made.

Using the bare earth in a standard twin and earth to be utilised as a live conductor is a definate no no, not sure which 2 way wiring method you were attempting here but the standard method is live to switch A, twin strappers between and a switch/live from switch B to light(s).

What wiring method have you done?

You might want to rethink that.!!!

No you can not use the earth as a live even if you sleeve it , mind you I have come across it a though times in installations best fix it take a switch wire from the second switch if possible if its a white plastic conservatory you might be able to get away with mini trunking depends on what your customer wants,

So your profile says your an engineer with an ONC. Hmmmmm

NO DO NOT use the cpc as a live conductor, totally against BS 7671 as well as being a dangerous installation method, saying that I have seen it done by unscrupulous Electricians, and I use the term Electrician with tongue in cheek, no self respecting sparks would do that, my advice for what it.'s worth would be to check your wiring in future before any wall finishing have been installed.

You could always install wireless switches instead.

Sell your customer one of these no need for the 2 way switch then

I hope you have public indemnity insurance.

Do not go cowboying because you've designed the install incorrectly. Front up, explain the error, destroy the plaster, and re-wire it properly.

Then, let it be a lesson for future works. Not trying to sound aggressive with you here, just saying it how it is mate.

Sorry Flanders buddy, but i don't agree with you here. He can't go selling his customers new products, that they didn't need (originally) or want because he's cocked up on the design process.

The customer has every right to take further action on him.

Who says he's a sparky? Who gave him DIY status?

EDIT: And he;s been on 1 hour ago and hasn't had the decency to update the thread with any responses....:32:

it's the OP's cock-up. fit the wireless switch at no cost to customer, after admitting he screwed up.
