Interesting bit of DIY

[springcrocus]

This photo View attachment 872 was taken from the rewire I am currently working on.

Here View attachment 873 is a close-up of the Henley block.

The T&E (7/029+3/036) running to the fused switch (switch fuse? never could remember which is which!) at bottom left is protected by the 100A service fuse. Bit of a bang if a fault ever occurred on the cable. :|

Needless to say, it has been disconnected.

TBH there's not a lot in those photos that I like

looking good. appart from that excellent install someones mum must be very proud of them hehe

That's why I'm doing a full rewire

The whole of the lighting circuit is in lead - you can just see two singles, heavily taped, going into the top left of the CU. The insulation has become very brittle and is flaking away.

This View attachment 874 is one of the lighting circuit jb's.

The rest of the circuits are imperial T&E, so date back to the sixties.

I'll post a couple more piccy's when it's finished

Great photos Sprincrocus, nice old wirings on the lights!

Thank You Spring,

I look forward to seeing those pics on completion, and possibly more of them, BEFORE completion.

Don't forget to pull all the old lead cable out and weight it in:run

 

[bengie]

forgive me if i am wrong but if that twin coming from the henley block only goes 2ft and into an isolater with an appropriately sized fuse whats the problem?

not as bad as this

29Kgms and still counting...

Bengie, I prefer to see a bit of cable protected at the front end rather than the back end. OK, accidental damage is unlikely but I still think that the near equivalent of 2.5 T&E on a 100A fuse is a bit too risky.

Would make a helluva bang if some twit chopped the cable. ]

Another interesting bit of wiring I found here. The socket outlet circuit was wired as a ring, covering both floors, BUT every socket was wired as a spur.

Eleven sockets and eleven JB's.... :_|

 

[bengie]

no arguments here, i personally wouldn't dream of doing that, all I'm saying is is there actually anything technically wrong with it?

this question only pops into my head as a similar question was asked before and it was pointed out that in the case of a spur from a ring you have a length of 2.5mm T&E protected by a 32A MCB when the cable's max load(without correction factors) is only 27A but its OK due to the fusing down at the load end of the cable.

i hate when people do that, be lighting or sockets.

oh yeah, the rating of the fuse will have no affect on the size of the bang will it?

overload protection can be omitted under certain circumstances

Funnily enough if all tests are ok there is technicaly no reason to replace lead cables.

I personaly would not like them but if IR and continuity is ok along with RCD additional protection they do not have to be replaced.

I was shocked when I first heard this. I am of course speaking in respect of any code you could give on a periodic rather than expert or informed advise on a rewire etc.

Just to finish this off, View attachment 885 is a picture of one of the JB's under the floor. The water pipe had leaked at some time and this JB was left sitting in a puddle. The pipe was fixed but the JB was left alone.

And View attachment 886 is one of the area tidied up. Then I remembered to fit the busbar cover :innocent

nice work
