SWA Fly lead

[SimpleSimon]

But it's not supplementary bonding.

Why can't you understand that?? The steel wire is not an extraneous part. For starters it's not part of a non-electrical condition because it's part of a cable!! Your not using the fly to bring it to the same potential your using it to earth the cable.

It's the same concept as having an earth wire in a bit of twin and earth. Can't get clearer than that.

 

[pblec]

so your latest presumption is the sheath is part of the cable,

now thats where i'm going wrong i'm saying the sheath is not part of the cable the cable is the cores the sheath is the armour protecting these cores, and with this being a metal part which will only become live under a fault condition will require supplementory bonding,

i was sure that bit of copper in T&E was the CPC and therefore part of the circuit.

are you now saying you presumed the sheath was being used as a CPC

 

[Engineer54]

Your wasting your breath Simon, ....Really!!!

 

[SimpleSimon]

Course it's part of the bloody cable!! Why do you think we're advised to use it as earth for the cable?!?

 

[pblec]

no please 54 when i get proved wrong i have to correct it so it can only improve me.

i'd guess there are plenty of people out there who don't know these things so its an educational process, we have to stay current and if it turns out i am correct with my assumptions then that can't be a bad thing as it shows some of you old timers on these boards have to be prepared to back up your statements rather than confuse us all with general coments

 

[pblec]

are you using its as the CPC or are you earthing it?

 

[pblec]

who's advising you to use that and why

 

[Silly Sausage]

I got accused of trolling earlier, I'm just an amateur next to this geezer

 

[SimpleSimon]

Are you telling me that in all your time you have never used the STeel wire of SWA cable as a CPC?

I'm going to get my book out in the morning and quote all the regs back to you till it's coming out of your ears.

 

[SimpleSimon]

are you using its as the CPC or are you earthing it?

Don't matter of the two I still ain't bleedin' bonding it!!!

 

[pblec]

Archy its not trolling please feel free to jump in, but be aware whats tripping everyone up is termanology on this.

a question was asked i answered but the question is terminology is the connection to the armour on SWA earthing or bonding, because earthing doesn't exost according to the regs but bonding does and i beleive this bonding is supplementory or aditional

I reckon this thread was more industrial than house basher so as you said earlier " pblec " to Mark on another thread best you get back in your box !

It's your terminology that's mixed here mate.

So the term earthing don't exist? What is it called when you connect the CPC of a circuit to the earth bar than??

pblec,

After 28 years in the industry as an electrician, you shouldn't really be having this conversation, ...but You are!!!

 

[pblec]

i have used the outer core of swa as a cpc but that wasn't the question

i couldn't use it as CPC when i first qualified as the firm i worked for didn't allow it and even now i won't - but that doesn't mean its wrong.

i'm sorry but what it does mean is you need to get your head in a regs book and refresh your knowladge a little, its not an insult i've just opened my green book tonight because of these forums.
