Cable Calculations?!

[Ian1981]

Cs is the soil thermal resistivity, this is a completely different thing to soil resistivity.
Resistivity (rho) is the electrical resistance per unit area of a material.
Thermal resistivity is the reciprocal of the thermal resistance of a material.

These two physical properties are very different things,

Dave I was mentioning a correction factor based on cables in soil cs which you say doesn't exist! And you've tried to turn it round

you stated that soil resistivity affects cable calculations, it does not.

What all because I missed the word thermal nice try

 

[gazdkw82]

Think we know what it is you meant

Get or borrow a copy of BS7671

I'm not trying anything.
Missing the word out made it a completely different thing

Now now children.... play nice.

I would like to point out that I did mention correction factors in my original post. But as you've elaborated on that a bit more than my generic terminology of CF are correction factors, so be it.

And not one to really sit on a fence, i think dave is right

Jesus you know full well what he meant. What is wrong with you?
