So I never did any tests about what gauge wire for 100amp service running x ammount of distance. But I surely am capable of hooking up a neutral and hot and ground wire to a sub panel lol. In this you run a single "super circuit" consisting of 2 hots, 1 neutral and 1 ground wire. You do not need a subpanel or ground rod by Code, but a ground rod is a good idea, as ground differentials could be dangerous. You wire one set of receptacles to hot1 and neutral. You wire the other set of receptacles to hot2 and neutral. I found lots of questions about this, but with many different answers. I'm looking to run a 100 amp line from my 200A main breaker box to a subpanel in my new detached garage. The run is about 120 ft.

Copper is the most .
The National Electric Code (NEC) requires a #4 American Wire Gauge (AWG) copper wire for sub-panels. If using an aluminum or copper-clad aluminum wire, a #2 AWG wire can be used. The minimum conduit size is 1.25 inches and a schedule 40 or 80 PVC electrical conduit is specified for lines run underground.
This means you need a wire with at least 45.5A ampacity. 8 gauge AWG copper wire has an ampacity of 50A; this is the wire size you need for an 8,000-watt generator. Example For Generator Amps: This is easier. Let’s say you have a 50 amp generator. What size wire do you need for a 50 amp generator? I have an old 220 (8/3 stranded with grnd) line off the main box from a stove that I don't use anymore (we have gas now). I want to use it to install a subpanel in my attic. The subpanel is 100amp, 6 space (12 circuit, main lug, indoor). The old stove line is coming off a 40amp double pole breaker in the main box. The main box is 200 amp.
