Finding the correct cable table

[rich3009]

A lot of these mock exam questions are not specific about armoured or non armoured multicore cables, flat twin or not etc, the correct table to use can be a bit of trial and error until you get the correct answer for Volt drop for example.

You been doing these questions for weeks

 

[rich3009]

On and off

 

[JAWS]

What are all these questions for mate? Are you doing some sort of course

 

[littlespark]

Nah. He’s writing questions for the new 18th ed courses

 

[Taylortwocities]

Maybe he does GCSE English lit questions for OCR?

Typical sarcastic electricians nothing changes

Problem is Rich we find the questions too difficult

Volt drop for 70°C cable is the same for the same csa and 90°C cables all have the same volt drop for a given csa, type of cable and installation method does not make a difference.
Only CCC is affected by the cable type and installation method.

shirley, though, with the heavier cables, the volts will drop more due to gravity????? .

No, No, No, the volts like copper and stick to it, so volts do not drop with gravity, that is why bigger cables have less volt drop, more copper to stick to so they do not slip out!

my bad. must be the electrons that suffer from gravity drop. or does centrifugal force keep them snug with all that orbiting around their respective nucleii.
