Indian electrical regulations are based on UK regulations and practice.
Installations often use UK type materials.
TT earthing is permitted, as it is in the UK, this being specificly prohibited by the USA NEC.
The usual supply to domestic and other small properties is single phase, 2 wire, 240 volts, 50 cycles.
Larger premises would have a 3 phase, 4 wire supply at 240/415 volts.
Colour codes are generally black for neutral and red for live on single phase circuits.
3 phase would use red, yellow, and blue for the phases with black for neutral.
Earth is green or green/yellow.
Enforcement of regulations is patchy, and standards of material and workmanship very variable.

But I have a notion the wit was wasted...........

You may be aware the the colour coding was changed in UK a few years ago.
I don't know if India followed suit.
The voltage is now nominally 400/230.

Gee whiz, we are actually gonna talk about electrical in this thread?
Okay, now I have a serious question:
If India's codes are based off the UK's, are the UK's based off the IEC or were they developed separately?

So the Britain completed the transition period from 240/415 V to 230/400 V per IEC recommendation. But still not so for India.

You can become an expert in any field with an online training course. Becoming licensed where you live is another issue.
You need to be an expert to work on that. The rest just use trial and error until they get things to work.Maybe because your installations would end up looking like this?

Yes I am aware of the new UK colours which we have been using for some years now.
AFAIK however India still uses the old UK colors.
The nominal voltage in the UK was indeed reduced from 240/415 down to 230/400, though the actual voltage supplied tends be still 240/415.
India however still uses 240/415 nominal.
It was a fudge in the name of "harmonisation".
The nominal voltage changed as were the tolerances.
In real terms, nothing much actually changed.
India was part of the British Empire so it was natural to for India to adopt British customs and practices. I think some British cars are still made in India that were superseded here a generation ago. I was thinking of the Morris Oxford but there it is called the Hindustan Ambassador and has been in production since 1958.Gee whiz, we are actually gonna talk about electrical in this thread?

Or a degree of insanity........

One reason we don't have any installations like that here is because of copper thieves:happyyes:

I think the OP was hoping you might have a copy of the Indian electrical standards.

I think
Section 8.2.2 & 8.2.3 on page no.73 & 74 of
http://cpwd.gov.in/Publication/GenSpec_ElectPt1Internal2005.pdf
may be helpful in this respect.

I see no maximum, but I do notice that copper strip 20mm x 3mm is allowed.
Look on page 79. Required materials are 'solid or flat copper strip'.

How do you know that any of that mess is copper?

The line is there that in case of copper earth conductor, it is not necessary to use more than 100 Sq.mm.
