The rule of thumb is 1mm square=6Amp so 10mm square will,for safety reasons and for a copper conductor, carry 50Amps.

How much load for 50mm2 cable?
There's no such word as "'Ampacity". The current carrying capacity of 50mm cable is around 300A continuous or 365amps @ 60% duty cycle. It's generally used for engine starter circuits or high current welders.Answer'Ampacity' is a North American term for the 'current-carrying capacity' of a cable. It is not used in most other English-speaking countries.
Would 10mm sq cable suit an 18kw 3 phase 415 volt motor over 25mt length?
The motor would draw about 24 kVA which is 35 amps. For this you would need 10 mm2 cable.
What is 10 french tubing?
It is a medical tube that 10mm in diameter.
What is the per meter weight of a 10mm deformed bar?
0.618
If ther are more than conductors in the raceway the ampacity of the conductors must be derated?
Ampacity must be derated depending on the number of conductors and the ambient temperature. In the Canadian Electrical Code Table 5C denotes derating for the number of conductors. 1-3 conductors = 100% load 4-6 conductors = 80% 7-24 conductors = 70% 25-42 conductors = 60% 43 or more conductors = 50%
What is the ampacity of a NM-B cable?
Allowable ampacity for 10-2 copper NM-B is 30 A.http://www.cerrowire.com/default.aspx?id=46
Is 10mm cable safe for 50a breaker?
10mm cable is overkill for a 50 amp breaker. You can definitely use it.
What is the ampacity of 70mm cable?
Capacity for cable 70mm (143-212 amp) and may vary depending on installation method used.
What is the ampacity of a 10-2 NM-B cable?
Allowable ampacity for 10-2 copper NM-B is 30 A.http://www.cerrowire.com/default.aspx?id=46
What is Wire ampacity?
It is a North American electrical term. It is a combination the words amp and capacity rolled into one word "ampacity". When talking about how much amperage a wire can legally draw, it is referred to as the wire's "ampacity".
How do you calculate the requirement of cable size for a given load?
If you know the size of the load to be served, multiply it by 125% ( times 1.25) and choose a conductor that is rated for that ampacity or higher.
Can you use aluminum service cable to feed a sub panel?
Yes, as long as it has the necessary ampacity for the load and is properly fastened at each terminal. For example, we have a 4/0 aluminum cable feeding our 200 A subpanel 120 feet away.

What determines the ampacity of wire?
Conductors must have an ampacity not less than the maximum load that they are supplying.
What determine the ampacity of a wire?
Conductors must have an ampacity not less than the maximum load that they are supplying.
What is an ampacity?
An ampacity is the root mean square of the electrical current which a device can carry within a specific environment, measured in amperes.
What is the ampacity of gold silver copper and aluminum?
The ampacity for copper is 1000A per square inch, in some places is 700A psi.
