the same as in the USA except
it will say 2.5mm instead of #10
or 25MM instead of 1000MCM
The frequency has no direct relationship to the size of wire. Wire is sized as to the amount of current a load draws in a circuit.
Not if it is secured and tightened properly and has the correct size breaker installed for the wire size used.
For accommodating 4/3 wire, a 1-inch conduit size should be used.
The minimum size wire that engineers spec for industrial and commercial installations is #12 and it usually is stranded not solid wire.
For a 100 amp service in copper, a wire size of 3/0 AWG should be used.
For a 100 amp breaker, a wire size of 2 AWG (American Wire Gauge) should be used to ensure proper electrical safety and performance.
For a 50 amp breaker, a wire size of at least 6 AWG (American Wire Gauge) should be used to safely handle the electrical load.
For a 50 amp breaker, a wire size of at least 6 AWG (American Wire Gauge) should be used to safely handle the electrical load.
For a 30 amp circuit, a wire size of 10 AWG (American Wire Gauge) should be used to ensure safety and proper electrical conductivity.
A conduit size chart for wire provides information on the recommended conduit size based on the wire gauge and the number of wires being used. It helps in determining the appropriate conduit size for safe and efficient wire installation.
As with any electrical installation, the wire size used depends on the expected maximum current the wire will carry. That cannot be determined by voltage alone.
For a 40 amp breaker, a wire size of at least 8 AWG (American Wire Gauge) should be used to ensure safe and proper electrical conductivity.
