Pyro Help Please

[trev]

As it's pyro, if this fault is anywhere other than at an accessory I'll show my bum in Primark window.
Once installed pyro will just sit there for years quietly chugging away and will outlast by many many years a T+E installation. My money is on something being disturbed at a fitting or switch, find that and it's good for flippin years to come

As said above. If they refuse to pay for upgrade and what you have done is not less safe than before. Note it on the cert and Job done
I think the ESC deem this an acceptable method Also.

Hi all

Changed a consumer unit today, Advised customer on PIR first but to no avail, so i changed the old consumer unit for a 17th edition dual rcd one, All circuits fine apart from the lighting circuit which trips instantly, Did the standard tests and found allsorts of problems with the neutrals and earths throughout the circuit , Now the problem i have is the entire installation is Pyro , Theirs no loft or floorboards ( second floor flat) so i have no minimal access to cabling, Advised the customer the lighting circuit needs rewiring, But they dont want to go for it and keep explaining to me " It worked before" ( May i also add the customer is polish!!) Now as a temporary measure until i get back their next week ive put the lighting circuit on the mainswitch side of the consumer unit , to atleast give the tenant lighting, Can anybody advise me on the best way to go about this as this work has to be certificated and i dont want to put my name anywere near this lighting circuit !

Many thanks

be it pyro or t&e theres a fault,just trace it and fix it,as has been said many times mention the word pyro and people panic,its just a cable,too many people rewire to get rid of a basic fault,if it was t&e would you rewire the circuit or fix the faulty leg

Is it acceptable to leave the Circuit on the main switch side of the consumer unit though?

Thank you

No its not I hope you fitted a FCU with a 5 amp fuse please say you did if not then you have a 60-100 amp fuse protecting the circuit

I interpreted this as on a cb on main switch. Could be wrong. If no cb I take back what I said lol

Well if he has configured it this way the circuit is now being protected via a CB instead of a 3036

Silly question but are you sure you haven't damaged the pot when changing cu?

 

[Guitarist]

If nothing else, always check LN-E IR before accepting a CU change. No good to u now, but any lesson learned is a good one

As i see it, you need to progress a testing exercise through the circuit, marking and inspecting each core as you go. As others have stated this sounds more like something has been disturbed, a pinched cable, or a previously damaged sleeve that's now allowing the conductor to come into contact with something. It's a bummer i know, but it needs to be fixed at the end of the day.... lol!!
