SWA - earthing the steel wire?

[ipf]

My stepson is a sparky & checks all the stuff I do & signs it off. He’s coming over next week to show me how to change the consumer unit!!

Why not ask him for advice, then?...….with all this regular work that you do.

'd prefer to see it earthed at both ends. Also will reduce the loop impedance.

I agree both ends, but from design perspective either/or should be used in calculations for a cpc not both.

Do you mean an earth rod?

 

[Taylortwocities]

No he doesnt. He means that if you use the armour + one of the cores for the earth then the resistance of the earth path will be reduced.

Ok

For him to be able to legally sign anything off, he has to be there at specific points in the jobs progress, he also has to be registered under a Third Party Certification scheme, is he?

Who'll be doing the required testing before and after the job and who'll be completing the Electrical Installation Certificates and Part P to LABC notifications?

It's worrying when we hear an amateur attempting a job that can potentially cause death or injury, if not now, but in the future; who doesn't know what they're doing. (Your original question proves that).

Professional, legitimate electricians have had to invest £1,000's in training, test gear, scheme memberships and continual updating of their knowledge and resources. We're professionals for a reason, we know what we're doing, amateurs don't, and with electricity that's a dangerous situation.

Harsh but fair

The regs are there for a reason mainly to stop people and animals being killed, but why not ignore them and take a chance it's only red tape

You don't need rcd protection for the SWA cable .Have you check with your stepson that you have the correct size of cable for what you are supplying ?

The cable is for a socket is it not?

Then fit an rcd socket , the swa cable does not require rcd protection.

I'm sure the OP's stepson will tell him everything he needs to do.
Not sure why he's here, if his stepson will be signing off everything.
Maybe he's on holiday....

Seems like you're being hard headed, is your football team losing?
Every cable requires protection!
I'd stick the rcd in a dB for many reasons. If you want I could explain them.

Nothing wrong in @Flanders post. It's to the regs.

Most rcd socket can't be Ir tested. It's suboptimal at best. Outdoor socket no ability to Ir test = trouble brewing.

What I said about every cable requiring protection is true. He said the cable did not require rcd - very misleading

I misread or he edited his comment. I thought it said cable did not require protection. Not rcd protection

Yes there are good reasons for both and im not saying you are wrong . Some cases it may be cheaper to fit an rcd socket than fit rcbo , or there no room in the board to fit an rcd , the list go on , or it could be easier and cheaper to fit an rcbo in the board .I was just pointing out that a SWA cable does not require rcd protection , O and I don't follow the football ☺

I've posted why rcd socket is a bad idea. Feel free to disagree.
I apologise for being harsh on you. I'll make an effort to to be nicer

That what I'm saying i don't disagree you can put the rcd where you like ☺ Just read my post properly in the future ☺ps i did not edit it .
