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
What would happen if the live and neutral wires were crossed in a 3 pin household plug?
Current in a standard house is AC (alternate) so it doesnt matter if the live and neutral are crossed. Should the earth and live be crossed then the earth leakage would trip
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.
Is brown live and blue neutral?
yes,because its a primary color
What is the blue wire for in a three pin plug?
In the UK Brown is the live, blue is the neutral and green/yellow is the earth. The live and neutral are the two wires that normally carry the current.
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 is the total of a phase to earth voltage on 11000 volts?
An 11,000 volt three-phase supply has a voltage of 6351 from live to neutral, when there is a neutral wire.
