Use only AWG # 10 copper.
Yes you can use #14 AWG romex for a receptacle as long as the breaker protecting it rated 15 amps or less. If it is a 20 amp rated circuit then you will need to use #12 AWG.
12 awg is larger.
Yes you can. You did not say how many amps were required.
Depends on the wire size used in the circuit. If you use AWG # 14 wire you must use a 15 amp breaker. If it is wired with AWG # 12 wire then you use a 20 amp breaker. If a AWG # 10 wire is used then a 30 amp breaker is required. The breaker protects the wiring from overheating so you must use the proper size breaker for the wire used.
LANs use AWG ratings between 22 and 26
No way
Use only AWG # 10 copper.
Yes, if you are using AWG # 10 wire. If you are using AWG # 12 then the answer is no you must use a 20 amp breaker. On AWG #14 wire you must use a 15 amp breaker.
Use a wire table to find the cross-section area of #33 wire, multiply by 7, then find the AWG for that cross-section.
No, you cannot.
240v ac
Normally AWG #10
A 100 amp service requires that you use AWG 4 copper wire or AWG 2 aluminum wire.
Yes you can use #14 AWG romex for a receptacle as long as the breaker protecting it rated 15 amps or less. If it is a 20 amp rated circuit then you will need to use #12 AWG.

14 AWG.
