I was expecting a bit more flack to be fair .  :)  There is also a massive difference to late 70's early 80s wiring than 60s. Although the standard of installation for a lot of the 60's stuff was excellent. The work that went into the wooden boxes and much of it installed in a form of metal conduit or tube..

Hi all. I hope this makes it more clear.

Oh deary me!


3.3 How could the absence of a label possibly be C2?


4.18 I assume that this is a TN installation so RCD is for additional and not fault protection.


5.13 This is domestic, not industrial.


Max permitted Zs column isn't right. Max Zs for a 30 A BS 3036 fuse is 1.04 Ω (Table 41.2). Where have the R1+R2 figures come from in respect of the socket circuits when end to end tests appear to have been omitted? Could it be Zs - Ze? Insulation resistance is low for PVC cables and why test at 200 V?

looks like it has already been rewired looking at the cable sizes.  ?

Can you get a 10kA rated BS3036 fuse?

There are a number of odd things here, suggesting the chap filling it out may not be the most experienced at this inspection lark, however even if half of it is a bit off, buried  in the details there are indicators the gist is right and this installation is getting a bit past it.

Roughly how old is the installation, or do you have pictures of the sockets flagged as overheated or the wiring in the airing cupboard?

The schedule of inspections, the observations and the test results don’t tally.


There are a considerable number of possible errors. It may need the complete installation replacing, however I suspect parts of the installation can be retained with a new consumer unit being installed and remedial work carried out.


You need to get an opinion from an electrician who can actually have a look at the installation, I don’t know what to suggest regards finding an electrician to do do.

It would take at least a hour to review the report and write a review of it.

Another fiasco born out of yet another "throw an idea at them (electricians) and let them sort it out" from the  "wiring regulations" The clue is of course, the IET have not themselves published their own "codebreaker" book, simply because there are, apart from exposed bare wires etc C1 no definitive answers. So causing havoc in the rental sector. The same with the steel fuse boards, throw an idea but dont define a solution. 


Ive read some of the codes, laughable, he has paid for, and that is what he has got.

Max permitted Zs column isn't right. Max Zs for a 30 A BS 3036 fuse is 1.04 Ω (Table 41.2).

That's 'cos they've decided that 5s disconnection times are appropriate for all the final circuits ?


It's complete nonsense (he said politely).
