A #3 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 100 and 115 amps respectively. A #1 aluminum conductor with an insulation factor of 75 or 90 degrees c is rated at !00 and 115 amps respectively.
Yes as long as you use an approved splice, such as a wire-nut.
No, number one copper is used in buss bars. "Number one copper" is a term I am familiar with from recycling copper. It does indeed include buss bars, but also includes any solid wire whose insulation has been removed, or large gauge wire with large strands (as opposed to small gauge stranded wire) whose insulation has been removed. -- Sparkfighter
bare copper is pure copper, while tinned copper is having light coating of Tin over it, preferred where soldering phenomenon is req. while the bare copper is good conductor then tinned copper.
Number 2 American Wire Gauge
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.
18 gauge solid copper wire is 40.3 mils in diameter, that is 0.0403" stranded would be larger.
no

34 gauge copper wire will work but to use the 35 gauge copper wire is the best choice

As a service entrance wire you need AWG # 3/0 gauge copper.
AWG # 4 copper.
Overcoat: Individual strands of tin copper stranded together & then covered with a tin coating. Topcoat: Bare (untinned) copper wire, stranded, then coated with pure tin.

A #12 copper wire with an insulation rating of 60, 75 or 90 degrees C is rated at 20 amps. This holds true whether it is solid or stranded.
