18 AWG copper wire is equivalent to 0.75mm2 nominal. The resistance of a particular copper wire depends on a number of factors like ambient temperature, the type and number of strands of conductor, when plated, the type of plating metal (e.g. tin, silver), etc.
A good value to use for solid #18 AWG copper is 21.8 ohms/km.

What is the required wire size for 100?
A 100 amp service requires that you use AWG 4 copper wire or AWG 2 aluminum wire.
What does AWG mean in wires?
AWG stands for American Wire Gauge, a standardized system used to measure the diameter of electrical wires. The gauge number inversely correlates with the wire's diameter; as the gauge number increases, the wire's diameter decreases. AWG is commonly used in North America to specify the size of wire for electrical applications, affecting both current-carrying capacity and resistance. This standard helps ensure compatibility and safety in electrical installations.
What size hot wires neutral wire and ground wire do you need to feed a 200 amp single phase sub panel coming from a 400 amp service?
For a 200 amp single-phase subpanel, you typically need to use 2 AWG copper wire or 4 AWG aluminum wire for the hot wires. The neutral wire should be the same size as the hot wires, so 2 AWG copper or 4 AWG aluminum is recommended. The ground wire should generally be at least 6 AWG copper or 4 AWG aluminum, but it's best to consult local electrical codes for specific requirements. Always ensure compliance with local regulations and consider consulting a licensed electrician.
What does minimum drive AWG mean?
Minimum drive AWG (American Wire Gauge) refers to the smallest gauge of wire that can effectively handle the required current for a specific application without overheating or suffering performance issues. This designation ensures that the wire can safely carry the electrical load while minimizing resistance and energy loss. Choosing the appropriate minimum drive AWG is crucial for the safety and efficiency of electrical systems.
What is the required wire size wire for 100 amp service?
A #3 copper wire with an insulation factor of 75 and 90 degrees C is rated at 100 and 105 amps respectively.
How does increasing the wire gauge from awg 22 to awg 26 generally effect resistance?
Increasing the wire gauge from AWG 22 to AWG 26 will increase the wire's resistance because a higher gauge corresponds to a thinner wire. Thinner wires have higher resistance due to increased electrical resistance per unit length. Therefore, a wire with AWG 26 will have higher resistance compared to a wire with AWG 22.
