Yes it can. It is 4/0 . Ne sure that the NEutral wire is the same guage as the hot legs. The ground can be #2 Alum
The recommended wire size for a 200 amp sub panel installation is typically 2/0 or 3/0 copper wire or 4/0 aluminum wire. It is important to consult with a licensed electrician to ensure the correct wire size is used for your specific installation.
For a 125 amp sub panel located less than 200 feet away from a 200 amp panel, you would typically use a 2 AWG copper wire or 1/0 AWG aluminum wire to safely carry the current load. It's important to follow local electrical codes and regulations when selecting the wire size.
On a 200 amp or any size service the ground wire is easily identified. Look in the distribution panel for the neutral bus bar. This is where the service neutral (white wire) is connected to the distribution panel. There you will see a bare copper wire connected to the same neutral bar. This is the ground wire that is connected to the ground rods out side of the house.
AWG # 3/0 copper.
To wire a 100 amp sub panel from a 200 amp main panel, you will need to install a double-pole breaker in the main panel to supply power to the sub panel. Run appropriate gauge wires from the main panel to the sub panel, ensuring they are properly sized for the amperage. Connect the wires to the corresponding terminals in both panels, following all local electrical codes and regulations. It is recommended to consult a licensed electrician for proper installation.
For a 200 amp service, you would typically use a 4/0 AWG copper wire for the grounding wire running between the meter box and the service panel. This size is suitable for carrying the necessary current and providing proper grounding protection for the electrical system.
For a 200 amp service, a minimum of 2/0 gauge aluminum wire should be used.
Yes, in a residential 200 amp panel, the neutral wire is typically the same size as the hot wires. This is to ensure that the neutral wire can safely carry the same current as the hot wires and maintain proper balance in the electrical system. Always consult the National Electrical Code or a qualified electrician for specific requirements.
The size of the ground wire for a circuit is typically based on the size of the circuit breaker protecting that circuit. For a 200 amp circuit breaker, the recommended ground wire size is 4/0 AWG (American Wire Gauge) copper wire. This wire size helps ensure that the ground wire can safely carry any fault currents that may occur in the electrical system.
There is no bonding jumper wire required on a 200 amp service panel. The meter stack is metallic and is continuous from the mast head down to the distribution panel. If you are talking about the ground wire for a 200 amp panel it requires a #6 bare copper conductor that connects the grounding rod or plate to the neutral point in the distribution panel. Assuming the answer above is an example of a service, where the meter is stacked above the first service disconnect and is mated to this panel by a threaded hub. However if your meter were to be mounted beside your first service disconnect and a metal nipple with lock nuts were used for raceway. You would be required to have a bonding jumper on that nipple sized according to NEC Table 250.122. So for 200 amp that would be #6 copper or #4 aluminum.
There are two things to think about here. First of all a 200 amp breaker will not physically fit into a 100 amp panel. This is so designed because the panel buss is not designed to conduct 200 amps before the current is cut off. A 100 amp rating on the panel is the maximum amount of current that the manufacturer states, that can be handled safely. Second if the 200 amp breaker is in the main panel then everything downstream from that breaker has to be rated for 200 amp conductivity. The wire size will have to be 3/0 from the breaker to the first over current device in the sub panel which will be the sub panel's main breaker. The sub panel can not be a load center but will have to be a combination panel. I doubt that the 100 amp sub panel's main breaker lugs would be large enough to connect the 3/0 cable.
No, you would need 2/0 (2 ought) in copper. In the US, 2/0 copper is allowed only in residential installations. Otherwise, 3/0 copper is required to a 200 amp service panel. The electric utility can use whatever they wish. They have their own standards and the NEC does not apply to them.
