Use #10 copper.
A neutral grounding resistor panel is used to resist fault current to the ground. It is used for alternator protection protection purposes. When a fault occurs in the alternator, the panel helps force the current to the ground.
#6 wire is needed. If placing the subpanel in a garage at a good distance, it is recommended to also install a seperate ground rod .
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
Notes: 1. Where multiple sets of service-entrance conductors are used as permitted in Section 230-40, Exception No. 2, the equivalent size of the largest service-entrance conductor shall be determined by the largest sum of the areas of the corresponding conductors of each set. 2. Where there are no service-entrance conductors, the grounding electrode conductor size shall be determined by the equivalent size of the largest service-entrance conductor required for the load to be served. 1 This table also applies to the derived conductors of separately derived ac systems. 2 See installation restrictions in Section 250-64(a).
Yes you do. The detached garage will either be fed with a single circuit or a sub panel. The wire feeding the garage will need to be protected and that is the purpose of the breaker (disconnect). The breaker size will be determined by the size of the wire that is used on this circuit.

For a 100 amp service panel, typically a #8 copper wire or a #6 aluminum wire is recommended for grounding purposes. It's important to follow local electrical codes and regulations when selecting the correct size of the ground wire. It's always a good idea to consult with a licensed electrician for specific guidance based on your individual circumstances.
A ground bar is used to connect the grounding wires of electrical circuits to the panel's grounding system, while a neutral bar is used to connect the neutral wires of electrical circuits to the panel. The ground bar is for safety, while the neutral bar is for completing the circuit.
We recommend using a #6 copper wire for the connection between the breaker box and the earth ground rod. This size wire is commonly used for grounding purposes and is sufficient for carrying the electrical current safely to the ground rod. Be sure to consult with a qualified electrician to ensure the proper materials and installation for your specific situation.
The size of wire needed for a sub panel installation depends on the amperage of the sub panel. It is recommended to consult with a licensed electrician to determine the appropriate wire size for your specific installation.

The ground conductor size chart provides information on the recommended size of the ground wire based on the electrical load and the type of wiring system being used.
No, the common (neutral) and ground wires should not be connected together in the main electrical panel. The common wire is used to carry current back to the electrical panel, while the ground wire is used for safety to prevent electrical shock. They serve different purposes and should remain separate.
For a 100 amp panel, a wire size of at least 3 AWG copper or 1/0 AWG aluminum should be used to ensure proper electrical capacity and safety.
If there is no ground bus in the panel, you can typically connect the ground cable to the enclosure itself. Ensure that the enclosure is made of conductive material and that it is securely bonded to ground. It's important to follow all local electrical codes and regulations when making such connections.
