1mm or 1.5mm T&E for standard lighting circuit in your average house.

[Leesparkykent]

Out of interest what's most commonly used?

 

[Midwest]

You haven't included bell wire?

 

[rolyberkin]

Use both 1.5 as standard but now starting to question why I do as most houses are LED now, I use 1.0 when on a rewire as it is easier to feed switches in old conduit.

Shirley (!) you use a cable suitable for the design, not 'cos of its physical size?

 

[AJshep]

1mm unless there is loads of Insulation surrounding my cables e.g. Celotex, Kingspan

Even if you halved 1mm's ccc (method C), it would still be 8A.

1.5mm2 don't know what Shirley used

If it satisfies the design then using size as a consideration is legit Shirley ?
I use 1.0mm almost exclusively, and the reduced size helps considerably on most rewires. Never have a problem with design considerations.

Me thinks you misunderstood my post?

Possibly ?

Sure about that ?

No but go on......

 

[Andy78]

I think 6A is the most onerous ref method in the OSG for 1.0mm

I'm misunderstanding yours now

Nah, just checked, it's 8A
