Bespoke installs

[kerching]

I actually have a 20mm one.....made by GB benders I think ( A Barrymore Company!)

must have had it 20 years

also got a set of RIDGID USA zones but obviously they are Imperial

will try to post a pic tomorrow

Complete with the instructions for offset and shrinkage imsellotaped onto the handle...posssibly some 25/30 years ago

very handy bit of kit and a doddle to,use when you get used to it

Flanged coulings with lead washer on outside and  serrated washer under the bush were fitted always on BT jobs . I worked on loads of exchanges from 77 to 87. We also had to wire ALL circuits with the next size larger cable, ie 1.5mm lighting  was 2.5, 2.5 rings were 4.0mm.

Also (and since i have learned has never been to BS) was the L was wired in the phase colour .

Oooooh ! I remember doing that Slippery but just for a short period , way back.       Red &Black .....Yell & Black.....Blue & Black  for single phase circuits ...can't remember on whose jobs now though . 

May have been pre- BT jobs  as in the old GPO , we did a lot of work for them .

I think it was once permitted for distribution circuits but not finals.

A company can determine its own specification outside the remit of BS7671. Finals with the phase colours are useful when you have 100’s of circuits.

BS7671 is advisory, not statute.

Yeah I meant under BS7671.

Correct.

imagine if it was still done today... remove socket A and you have blue & black. socket B and you have black & blue...

 

[Lurch]

It'd be OK as long as you put a sticker on the board!

Most installs using phase colours were conduit not T+E. Extending a circuit common sense would say stick to the original colours.
