If I would want to know which cable size I have to use, I would try Google or some electric expert site.

AN is not the place to search for this kind of information.

Actually a "useful electrical sites" thread might be a good idea, possibly include places to get those unusual items (such as "intermediate" switches).

 

I too use Doncaster Cables calculator as it's pretty idiot-proof and gives results in metric rather than AWG which many others do being US-centric. Unfortunately, it doesn't calculate for aluminium cable, although simply going one size larger for Al seems to be a pretty general rule.

 

One problem which we're sure to encounter is regulations do vary around the world.

 

Let me apply my (small and aging) brain. We've tried similar in DIY and it got to be unmanageable.

The following calculator is based on Aus/NZ standards annd  allows for many factors including type of cable conductor, insulation, voltage drop, and installation conditions.

i mentioned this the other day, might be worth asking the boss if you can do it
but i think some mods here are very knowledgeable on specific topics
it would be nice to have threads on specific topics that certain mods have knowledge on, created by said mod
and HEAVILY moderate them, removing all low or no value comments
so the thread is basically owned by the mod that creates it, to provide useful info.

Please pin also a sentence like this:

 

Don't mess around with mains if you don't know what you are doing. It could kill you.

 

That will answer at least half the questions in this forum.

Image added to the pinned Local Forum Rules thread which already had said warning.

 

Take care out there.

After seeing thai builders only insist on certain brands of cables, I've noticed that the actual cross section of certain *off brand* cables are smaller than the more expensive brands
