Because the resistance per meter values of the conductors are given at an assumed temperature of 20

I'm not aware that Appendix 4 contains resistance per meter figures?

I'm not aware that Appendix 4 contains resistance per meter figures?

The resistance figures in appendix 4 are based in an operating temp of 70 C spin, so no need to apply a factor.

 

[spinlondon]

What resistance figures in Appendix 4?

Could you give a page number?

 

[Chr!s]

273 to 317

 

[spinlondon]

Those figures are not resistance per meter.

They are current carrying capacity and voltage drop figures.

 

[spinlondon]

Never even considered looking at those.

Was taught to use the Tables in GN3 for some reason.

I agree that you may have been mislead, you apply the 0.8 or 1.2 factors when calculating R1+R2 values, not on the current carrying capacity
