Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.
I would install a 60 amp sub-panel and use AWG #3 copper.
A 200 amp service panel with a 60 amp sub-panel.
A 100-A sub-panel would be fed from a 100-A breaker.
A domestic D/W uses 14 gauge wire.
Use 1/0 gauge.

No, a 12 gauge wire is rated for 20 amps, which matches the breaker size. It is not recommended to use a wire that matches the breaker size as it can result in overheating and potentially cause a fire hazard. Consider using a thicker wire, such as 10 gauge, for the 20 amp breaker to ensure safety for the sub panel.
Aluminium wire has produced problems due to unequal expansion/contraction at the brass or copper terminals and long-term surface oxidation. For that reason copper is recommended and there is usually no good reason not to use copper (of the correct gauge for the current).
For a 100 amp sub panel located 250 ft from the main panel, you would typically need to use 3/0 aluminum wire or 2/0 copper wire to ensure efficient power transmission and voltage drop within acceptable limits. It is recommended to consult with a licensed electrician to ensure the appropriate wire size and materials are used for your specific setup.
I would use 4 AWG copper to be safe.
I would install a 60 amp sub-panel and use AWG #3 copper.
For a 200 amp sub panel located 30 ft. away from the main panel, you would need to use 3/0 copper or 4/0 aluminum wire to handle the load and distance. It's recommended to consult a licensed electrician to ensure the correct wire size and installation for your specific situation.
It is not recommended to use a 40 amp breaker to feed a sub panel, as the breaker size should be based on the size of the wire and the load of the sub panel. It is important to follow the manufacturer's guidelines and local electrical codes when determining the appropriate breaker size for a sub panel.
For a 60A output from a generator to a distribution panel, you would typically use a 6-gauge wire for copper or a 4-gauge wire for aluminum. Make sure to also check local electrical codes and guidelines to ensure correct sizing and safety compliance.
== == === === Gauge #6 wires are best for this application. The breaker and wire should fit in your main panel unless it is already overloaded. Get advice from an electrician. ----- See Discussion for additional information As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
