The typical rating of a hot wire relay contacts is 35 amp
A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively.
A #4 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 85 amps.
You never, ever mix wire sizes within a circuit. However you can wire a 30 amp circuit using AWG # 8/3 wire, although that is overkill and AWG #10 wire is what you would normally use on a 30 amp circuit.
Yes, the wire size has to be increased. The existing 100 amp service will now probably have a #3 conductor with an insulation factor of 75 or 90 degrees C which is rated for 100 and 105 amps respectively. Increasing to a 150 amp service will use a #1/0 wire size. If you are thinking of an upgrade, skip the 150 amp service and go to a 200 amp panel. New homes are installing 200 amp 42 circuit panels. The extra cost is only reflected in the materials as the labour costs will be the same regardless whether a 150 amp or a 200 amp panel is installed. The wire size for a 200 amp panel is #3/0. With an insulation factor of 75 or 90 degrees C the rating is 200 or 210 amps respectively.
The amp rating of NM (Non-Metallic) wire varies depending on the gauge of the wire. For example, a 14-gauge NM wire typically has an amp rating of 15 amps, while a 12-gauge NM wire has an amp rating of 20 amps. It is important to consult local building codes and regulations to determine the appropriate wire gauge and amp rating for specific applications.
A 3-wire circuit could have different amp ratings depending on the type of wire and the application. In residential settings, a common amp rating for a 3-wire circuit is 20 amps, which is typical for general-purpose lighting and outlet circuits. It's important to consult the local electrical code or a professional electrician to determine the appropriate amp rating for a specific 3-wire circuit.

A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively.
A 16-gauge wire typically has an amp rating of around 10-15 amps, depending on the type of insulation and wire composition. It is important to consult the manufacturer's specifications or a professional electrician to ensure safe and proper usage.
No, you should use wire that matches the lowest amp rating of the breakers connected to it. In this case, you should use 15 amp wire since one of the breakers is a 15 amp breaker. Matching the wire gauge to the lowest amp rating ensures the wire is protected from overheating in case of a short circuit.
Wire size is rated by Amperes of current. You did not mention the wire size of the aluminum wire, so there is no way to answer your question. The voltage rating is more a rating of how good the insulation around the wire is.
A 3/0 copper conductor with an insulation rating of 90 degrees C is rated at 225 amps.
A 3/0 copper wire with an insulation rating of 90 degrees C is rated at 210 amps.
