Several answers are possible here (this sounds like a test question, by the way). NEC 210.19(A)(4) says that branch circuits that are not for cooking appliances specified in 210.19, or specific-purpose loads specified in 210.2 shall not be smaller than #14 copper (#12 aluminum). 310.5 says that all wiring 0-2000 volts shall be minimum #14 unless otherwise permitted elsewhere in the code. There are perhaps other references too, these are two that come to mind.

What is the name of the wiring on the 380 volts system?
depends on the amperage. 14 AWG for 15 amps, 12 AWG for 20 amps, 8 AWG for 50 amps.
What is the largest size solid conductor permitted to be installed in a raceway?
10 AWG can be solid. 8 AWG and larger should be stranded. 2008 NEC 310.3 2011 NEC 310.106(C)
What is the smallest wire size for which overcurrent protection is specified in the Code?
14 AWG
What kind of aluminum wire has the most resistance?
The one with the smallest thickness (highest AWG number) and longest length has.
What size wire to pull 6 amps 70 feet?
NEC 310.16 conductor ampacities NEC 240.4(D) For residential installations the smallest wire to be used is 14 AWG (15 amps rating) and for commercial installations the smallest wire to be used is 12 AWG (20 amp rating)
What is the smallest size wire to run in parallel permitted by NEC?
NEC Section 310.4 requires a 1/0 AWG and larger be used in parallel.
Which wire is smallest in AWG?
The larger the AWG number the smaller the wire. 10 AWG wire can carry more current than 12 AWG wire.The wire sizes of 24 and 26 are the smallest that are used in the electrical.See related links below
Does a 1000 watt single pole switch require different wiring than a 600 watt switch?
not unless the wire is exceptionally small, if if is 12 AWG or even 14 AWG you will be ok unless you are using it for a transmission line (unlikely) The smallest wire you can use safely is a 21 AWG wire but that's not a wire used in the walls

How many No2 Awg THHN wires will fit in a 1 conduit?
According to appendix C of the NEC, 3 #2 awg are permitted in a 1" EMT.
What is the smallest wire size for which overcurrent protection is specified in the Code?
14 AWG
What is the minium branch -circuit wire size that may be installed in a dwelling?
Under modern code, the 14 AWG copper conductor is the smallest branch-circuit wiring size, based upon 15A overcurrent protection.
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.
What is amp rating for 8 to 14 gauge aluminum wiring?
There is no rating for #14 wire in the electrical code book. This is because #12 aluminium wire is rated at 20 amps and that is the minimum of home wiring circuit wiring in aluminium. It is not, if at all, used anymore. #10 at 75 or 90 degree C is rated both at 30 amps. #8 at 75 or 90 degree C is rated both at 45 amps.
What size romex for wiring 6 can lights on 15 amp circuit?
You should use 14 AWG wiring on all 15 amp circuits.
What is the smallest breaker for a 25 amp circuit?
30 amp wired with AWG # 10 wire.
