A new world record, well for me

[trev]

Got a call a couple of days ago to a boiler which had been looked at by a gas guy who advised of an earth fault and that he had isolated it. So I bowled up today, there was a VOELCB right by the BS3036 CU which had excessive charring on it, some fuse carriers were crumbling others were cracked and in several bits. No cover for the fuses of course and the carcass was falling apart, the only saving grace was that it was up a height.
Obviously alarm bells are ringing quite loud so I looked a bit further, not a scrap of bonding anywhere in the place IP ratings severely compromised so I thought lets get the test gear out, IR really low RFC continuity non existent etc etc. The owner of the place turns up and so I start talking to him about a rewire which he told me to prep a price for, I thought now is a good time to check the EFLI, now it's a TT so I expected something fairly high but not as high as 1356 ohms.
It's a new record for me guys but I'm sure one of you can beat it

well now ive read this , i will let you know, il even test houses when just visiting someone in countryside. trev will beat it

 

[DurhamSparky]

this is the best ive had...!

Eng54 has been warning about those twigs for years!!!

1061 ohms is my best so far, can't beat 1356 ohms, sounds like you are onto a fun job there!

Only about circa 500 and odd ohms for me,
This one had no rod and no bonding, I think it was reading through the CPC via the supply cable to the combi boiler.

Iam sure I will come across a higher one sooner or later, lol

Cant remember if it was 1240 or 1420. It's in a thread on here somewhere, I'll see if I can find it.

Thing is Richard I know for a fact with a bit of work and some big fat rods I can get that way way below 50 ohms and that'll be stable so that's not the problem. I just did some rough sums and the we're looking at £2.5k ish for the rewire which I'm pretty sure my client won't go for, I've done an EDN because what I found scared me but he has tenants in there and he's already ringing me and asking can I not just change the CU and dig into the existing problems and put them right as I find them.
I've got a feeling this client is going to be a total pain in the bum.

If the customer is a landlord and the property is rented i would cut him no slack whatsoever lol.
The fact the install still has an veolcb suggests its as old as the dinosaurs and has simply come to the end of its useful life.
What type of cables Trev ?

 

[trev]

It's all T&E as far as I've seen Biff but the IRs were terrible and it's all just crap. I reckon there's been some DIY over the years by the standard of it, no CPCs sleeved anywhere, some CPCs missing etc etc you know how it goes.
He's getting no slack from me whatsoever mate, he'll get my price Monday or Tuesday if he wants to go ahead then fine. If not he can find a cowboy. Either way I don't mind

and i'd make sure the quote was at least 3K. he'll get that back in 9 months rent anyway.

it's a TT so I expected something fairly high but not as high as 1356 ohms.

If we go by what others have clearly stated here on the forum, all you need to do is just bung an RCD on it and the jobs a good-un ...Your allowed 1766 ohms for a 30mA Rcd don't you know!! LOL!!!

 

[telectrix]

with ref. to all the TT posts that have been flying around lately, i've decided to perform an experiment. we are built on sand. don't know how deep it is, but i'm going to try for a sub 10 ohm Ra. if i go deep enough and hit oil, that will be a bonus.

Oh well, maybe I'll just shove an RCD in and forget about all the problems and walk away

 

[telectrix]

think eng54 was being sarcastic, there. i'm going to bang in rods till i hit bedrock, pi$$ on ot , and see if i can get a TN equivalent reading.
