A couple of testing questions

[Guest55]

and 16mm swa only holds 80 ish amps clipped direct so i hope the dno fuse isn't 100a.

Cheers Biff, at someone agrees:smug:

Sorry the word aggressive may have been a bit strong but to end replies with 'personally I think you're taking the ****, ' 'wrong sooo wrong (without explaining why I am wrong sooo wrong)' and 'just who the hell taught you anyhow' are a bit out of order when all I am trying to do is get some advice.

Your last reply 'If you can't be bothered to terminate and earth your selected cables properly or find testing a simple sub main like to much graft, that's fine, I hold any future comments and replies back' just completley enforced the point I was trying to make in my last post, I CAN be bothered to do it, thats why I spent all last night trying to get some info on the CORRECT way of doing it, that's the whole purpose of me posting on this forum. If you look at my posts I am repeatably asking how to test a sub main, why would i be doing this if I found it too much graft?

I really don't understand this forum..surely it should be a simple format such as..

a) a person posts a question they don't know the answer to
b) someone reading the post who knows the answer, replies back

Hallelujah.. thanks Biff..finally get an answer I was looking for.

 

[dtec dave]

..but still don't have an answer to my original question in post#1..but will probably look for the answer elsewhere before I top myself!

The cable feeding CU2 would be included on the test sheets for CU1 as it's a circuit fed from there. At CU2 instead of a Ze for it you would record Zdb.

Evening all

I am in the process of re-wiring a 4 storey property and have 2 c/units, 1 in the cellar and 1 on the 2nd floor. I have run a cable from the henley box up to the 2nd c/unit on the 2nd floor and I'm wondering if I need to provide test results for this cable on the schedule?

Also the job is being done in stages over the next year so do I need to provide an EIC for every stage and then at the end of the job rip all these up and provide just one EIC for the whole installation?

Cheers

you will have a total of 3 EIC's at the end of the job.
1. basement CU
2. 2nd fl CU
3. submains to 2nd fl CU. ( if you fit a switchfuse at the mains )
write out each cert as each stage is completed.

Trev..I haven't fed cu2 from cu1..cu2 is fed dierct from the main incoming tails via a Henley box.

Trev..I haven't fed cu2 from cu1..cu2 is fed dierct from the main incoming tails via a Henley box.

My apologies, I think I'd treat it as two separate installations then. As I said in an earlier post you don't have to have 1 test sheet for one installation, number them sequentially and cross reference them if necessary.

Thanks Biff..I get it now, I'll get to work adding a switch fuse.

 

[Guest55]

thinking about it , you could just do 2 EIC's as trev suggests , combine submains and 2nd fl on 1 cert with 2 circuit shedules.

Sorry to butt in, but you got the answer you were looking for early on in the thread...just seemed you didn't like that answer. Just an outsiders' perspective. Anyway....pretty basic stuff that you can't just feed a long distribution circuit by splitting the tails in a Henley Block!

By this I assume you mean post 14..yes this was the post that got me thinking I'd done it wrong so when I tried to get more info about it I was just told 'i was taking the ****'

This SWA submain you have put in needs taking out of the 'Henley box' and terminating into a suitable switch fuse. Feed said switch fuse from your Henley with tails.

Its a circuit so requires testing, same as every other circuit.

Your Ze is at the origin it will be Zdb at CU 2.

You will still need list this sub main as a circuit on your STR along with all the boxes completed.

You are allowed to use more than one test sheet you know.

Who the hell has taught you the game anyhow?

You're making life hard for yourself.

Why fart about doing what you've done.

SWA needs fusing so gland off into a meta lclad switch fuse and feed it with suitably sized tails, job done.

If the SWA sub isn't glanded off properly then its not safe and you can't properly complete your cert.

Personally now think your taking the ****

direct from the service fuse ?
should be fused down and switched if more than 3mtrs from meter , which it clearly is.

Ha Ha, don't just think it was one single post that gave good info on this situation :sad_smile:
