[Amp David]

Come on Malc, whats that in English lol

 

[Amp David]

[Paul.M]

Special order (at the time) of 5mm? Where has it come from.

 

[malcolmsanford]

ahhhhhhhhh should be AWG 12 then but not bad without the conversion books, I hate AWG it's the cheapiests nastiest stuff in gods green earth.

Special order (at the time) of 5mm? Where has it come from.

Its from a supply to a garage. 2 core. Was installed in 1989.

Why isn't it a standard mm squared?

 

[rocker]

Because they're yanks mate, they only have inches

 

[Paul.M]

I've been told by the old boys that it is possible to order any size, any colour, any core you want from a manufacturer. Why they would go for this in-between size is any ones guess. I think it may have been a bad batch of what should be 6mm, sold cheap and still used. How many strands does it have? (how much can we debate this 2 inch of cable?)

1989 ........................could be a bit of old 7/044 or 7/036 that a sparks found in a bottom of an old pile.

Its made up of seven strands.

Yeah, I know that. What I was meaning is why is it being used here in the UK, would of thought that in 1989 it would of been metric.

Can't see it being an odd off cut either, as there are 11 houses with the same install into the garage, all with a run of 12 meters.

 

[telectrix]

try measuring the resistance. and swg is english, it's them damn meters that are foreign. meters are for putting shillings in to make the lights work

 

[Amp David]

Whats SWG saint?

 

[telectrix]

standard wire gauge. as on 7/029, now replaced by 2.5mm. the 7/029 was far superior. just done a CU change where most was 7/029 for ring finals. 3/029 for lighting. all readings well perfect and it's 40 years old.st on case you don't know already. the 029 is the swg of each strand, and the 3 and 7 are the no. of strands.
