rcd protection

[rdelectrical]

hi guys I've recently installed an saw cable from mains incommer to ccu which moved from old position in a property as i said I've used swa from outside electricity box into loft in bungalow then swapped to pvc 16mm via proper terminations enclosed ran it along onto of insulation in loft away from everything then into trunking in hallway cupboard in to new ccu this was brought about because firstly i came thru from outside into zone in kitchen up a zone properly chopped in and capped came up where extractor was to be we agreed before no vent and steel splash this was so i didn't have more than a metre of metre tails going up wall the diy ers decided when installing cooker hood to remove cables from skt outlet which fell under vent hole they dug them out then chopped a 2 brick hole found buried 16mm took off capping thought it was cooker cable proceeded to cut and yes they blew main fuse i got call being accused of **** work so i installed the above swa to which they now are saying is wrong now i know I'm right does anyone agree sorry its a long post i would usually just have run swa all way to ccu without changing but the diy ers wouldn't pay and i didn't want to leave the elderly couple who they where doing it up for without power they basically want cable back where it was i refused as theres now a huge hole where it was cheers for your answers and patience

Would you like to edit your post, adding punctuation? paragraphs? and make it readable?

 

[IzzyS]

My keyboard has a button that does this . . . . . . .


I can't make any sense of your post. Sorry.

Fill the hole, Put the cable back where it was, add the required rcd.
Now the swa is a longer run have you put in a switch fuse? If not that maybe what they are saying is wrong.

what i meant was due to old consumer unit being moved due to new kitchen i ran 16mm pvc from mains income cupboard outside through wall which came out in 2 zones it went up wall 50 mm deep in capping vertically behind cooker hood run was about a metre then into loft across then down trunking to new board the 16mm was in zone with skt outlet to plug in hood which would be behind the vertical vent cover the people doing the kitchen knew it was there agreed to use grease filters and not vent outside as vent would be higher than the skt for hood they after id gone dug out ring main for hood along with 16mm cut a 2 brick hole for vent leaving no where for cables to go then cut mains thinking it was cooker cable with the intention of reconnecting themselves when it went bang i got blame so as to try to help i had no choice to but to go in swa outside upto loft height then back in and swapped back to 16mm pvc they now are saying this is wrong i believe I've done it correctly as it was in first place

That now makes better reading.
Tell them what you have done is fine (personally id have binned the t/e and just used swa) and invoice them for repair work.

cheers not clever i told them they should pay they refused i didn't want to see old couple without power so hence only used swa for short run besides ccu is plastic mad thing is i didn't want to run the the cable inside in first place as i don't like long metre cable runs especially in wall but they didn't want swa cable outside the very thing they ended up with they wanting cable back in wall after they dug it and cut it thinking it was cooker cable i refused point blank and they destroy it yourself ers and may do it again they said been onto niceic but to me it was right first time and is right second time

I'm trying to catch me breath after reading that.(full stop).(twice)

 

[rdelectrical]

lol too make it short some muppets dug out a cable cut it thought oops ill blame sparks

 

[davesparks]

But what is your question?

I don't understand how they blew the company fuse? Why did the RCD you installed to protect the buried PVC cable not operate first?

And how did you get around the requirement to not have the whole house on one RCD?

What protection have you installed for this distribution circuit?

 

[rdelectrical]

the original ccu was located just the other side of the wall from the mains box due to new kitchen a new ccu in same place would have ended up low level inside kitchen cupboard which the cupboard is pull out type so had to be moved so i installed new metre tails 16mm pvc pvc cable 50mm in wall and capped they dug it out because wanted to put vent in wall assumed was cooker cable it ran up wall in zone into loft and to new position for new duel rcd board i didn't add rcd for this circuit as its a distribution circuit i believed at 50 mm in wall capped was ok they now disagree because now have swa on outside and want original put back but because they dug out a vent in its place can't happen

I hope you used 3 core SWA from the DNO cupboard, or 2 core with an additional suitably sized earth conductor and Didn't use the steel armour of the SWA cable as your main earth??

 

[rdelectrical]

plus for the metre in the wall it ran a cooker hood was going there plus steel splash back

 

[rdelectrical]

no i used 3 core i even earthed the armouring which is what i wanted to do in the first place they just upset cos now cable is on outside they was going to cut cable and reconnect without telling me
