Answer for USA, Canada and countries running a 60 Hz supply service.
Equipment grounding conductors are not based on the size of the live and neutral conductors. Equipment grounding conductors are based on the amp rating of the circuit, which may or may not be the same ampacity of the conductors of the circuit.
However, working backwards, a 16mm conductor is the same as a 3/0 conductor, which is rated for 200amps, which requires an equipment grounding conductor (earth) of at least 6 AWG copper / 4 AWG aluminum. If your circuit is rated higher (usually the breaker size) than 200 amps a larger conductor may be required.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What are live and neutral and earth wires for?
The correct term for the 'live' conductor is the 'line' conductor. The line conductor has a potential of 230 V (in UK) with respect to the neutral conductor which is at approximately the same potential as earth. This potential difference provides the 'driving force' for the current drawn by the load.
Does a toaster use a neutral phase?
There is no such thing as a 'neutral phase'. 'Live' or 'hot' conductors are called 'lines', whereas the neutralconductor is at approximately earth (ground) potential.So, a toaster would be connected between a line and a neutral conductor.
Your wall cooker socket wires are black green and red which is which?
Red - active, (commonly known as your live cable) Black - Neutral Green - Earth
Is red neutral or live in a 240 volt system?
The colour red designates that the wire is used as a live wire. The neutral wire is identified as white in colour.
In the UK what cable should you use for a domestic ring main?
The cable usually used is 2.5mm2 three core (live, neutral and earth). In circumstances where the cable runs are long or derating is required due to temperature 4mm2 is used. The ring main is usually protected by a 32A circuit breaker. In older installations a 30A fuse was used.
What colour earth neutral and live in armoued cable?
All depends on what country you are in, wiring standards and cable type. Industrial cable in the UK is. :- Red = Live Black = Neutral Copper wire = earth. (add Green/Yellow striped sleeve at junctions.) Domestic is:- Brown = Live Blue = neutral Green/yellow stripe = Earth Europe Black = Live Blue = Neutral Brown = Earth
Can there be 230 volt potential drop in both neutral and live socket practically?
This question is not quite clear but I will try it somehow. The voltage drop between the live and neutral, and live and earth will both be 230v, but the voltage drop between the neutral and earth is almost zero due to the fact that the neutral and earth is basically one conductor split.
Why do outlets have 3 holes?
Live, neutral and earth. The supply is carried on the live and neutral, and the earth normally carries no current, but if there is a fault the earth is there as a safety factor and in some conditions it carries enough current to blow the fuse and make the circuit safe.
How many conductoers are there in single phase line?
Three: Live, Neutral and Earth
Why are there 2 prongs on a plug?
It is the minimum required to complete a circuit. You need a live and neutral. A two pronged plug does not have a saftey Earth connection. The device operated must be double insulated and have no metal parts visible, that could become live.
What is the neutral current?
I think you mean "what is the permissible imbalance between live and neutral current" All current supplied by the live wire should exit via the neutral. Any imbalance leaving via Earth is detected by an earth leakage circuit breaker . They trip at about 30 mA.
What is the permissible neutral current?
I think you mean "what is the permissible imbalance between live and neutral current" All current supplied by the live wire should exit via the neutral. Any imbalance leaving via Earth is detected by an earth leakage circuit breaker . They trip at about 30 mA.
What are the three wires in a plug called?
The green and yellow is the earth wire The brown is the live wire The blue is the neutral wire A poem to help is: The brown live cow drinks from the blue neutral water and eats the green grass from earth
What are the names of the three wires in a plug?
The three wires in a plug are typically called live, neutral, and earth wires. The live wire carries the current to the appliance, the neutral wire completes the circuit and carries the current back, and the earth wire is a safety feature to prevent electric shocks.
Can a live and earth wire be joined together in a light switch?
Physically yes, but to no avail. The breaker will trip instantaneously as a short circuit will have been introduced into the circuit with this action. In all wiring the live must never be connected directly to earth. The only place where the neutral and earth are connected together is at the distribution panel where the utility's supply neutral joins the system earth on the distribution panel's neutral bus bar.
What color is live wire in old plugs?
In the UK, the old wiring colours were... Live = red, Neutral = black, Earth = green.
What position would you find live electrical wire?
You would find a live electric wire, with a neutral and usually also an earth wire, in any place where electricity is used. The wires are colour coded differently in different areas but in Europe live is brown, neutral is blue and earth is green/yellow.
