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 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.
What size wire do you need for a 100amp braker?
Service entrance wire should be AWG #3 copper.
What size feeders for two 225 amp panelboards?
Use AWG #1 copper service entrance wire and #4 copper ground wire.
What size wire for a 40 amp breaker?
A 40 amp breaker is used in conjunction with AWG # 8 copper wire. The black and red wires are connected to the breaker. The ground wire is connected to the ground bar and the white wire is connected to the neutral bar.
What is the characteristic resistance of 14 AWG solid copper wire at room temperature?
0.06411.628142.5258.2825.96700 Hz
What is the size wire for 200 amp?
At least 000 AWG copper or better yet, 0000 AWG copper. Another consideration is how far the 200 Amps are to be carried. Wire has resistance and 0000 copper has a resistance of .04901 Ohms per thousand feet. At 200 Amps, this means that over one thousand feet the voltage will be 9.8 Volts lower than at the starting point.
What are some commercial uses for 9 solid copper wire?
Beats me, the National Electrical Code does not list a #9 awg wire.
How does increasing the wire gauge from awg 22 to awg 26 generally effect resistance?
Resistance will increase.
What is use 2 in copper wire?
Use 2 in copper wire refers to the American Wire Gauge (AWG) standard for copper wire used in electrical applications. AWG 2 copper wire has a diameter of 0.2576 inches and is commonly used for high current applications such as industrial machinery or power distribution systems. It can carry a maximum current of approximately 190 amps.
50 amp breaker needs what wire size?
6 AWG wire
What is gauge 8 means in copper electrical wire?
In cooper electrical wire, gauge 8 means the wire size assigned by the American Wire Gauge (AWG) system. That is why you always will hear about AWG WIRE, it's not the type of wire is the gauge that we are talking about. A gauge 8 wire will be used for connections requiring from 40-45 amps to a maximum of 73 amps. (24 for power transmission). Diameter of an 8 AWG wire is 0.12849 inches. 8 AWG is solid, not stranded.
What is the smallest copper wire size permitted by the national electric code for a 20 amp single phase electrical circuit?
I think you mean either what is the correct size or minimum wire size needed when a branch circuit is protected by a 20 A breaker. The size is 12 American Wire gauge (AWG). 14 AWG is used for 15 A circuit and 10 AWG for a 30 A breaker. The lower the gauge the larger the cross-section of the wire.
How decide Electrical Main Feeder size?
It is based on the amperage of the service panel in a single phase home panel useing copper wire use. 100 amp use AWG # 3 copper 200 amp use AWG # 3/0 copper
What size wire for electric cook top?
AWG # 6 copper or AWG # 4 aluminum
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 type of wire gauge should be used for a 20-amperes circuit?
Yes, 12 AWG is good for 25 Amps if copper wire.If aluminum wire, then good for 20 Amps.
