For a 200 amp service, it is recommended to use 3/0 copper or 4/0 aluminum wire. These wire sizes are suitable for handling the electrical load of a 200 amp service with the appropriate safety margin. It is important to consult with a qualified electrician and adhere to local electrical codes when determining the wire size for a 200 amp service.
Yes, but at every reduction in wire size there has to be a breaker sized to the smaller wire size. The wire size for 100 amp panels is recommended at #3 copper conductor. From the 200 amp feeder panel you will require a 100 amp two pole breaker for each of the two 100 amp services. Keep in mind that if you run the 100 amp services close to maximum this will take away the capacity of the 200 amp service for other branch circuits coming off of it. Also keep in mind that if the panels are located, not in the same building as the 200 amp service that the 100 amp panels will be treated as separate services and will have to be constructed like a 100 amp service. This includes ground rods. Also the bonding screw will have to be removed that connects the neutral buss to the panel enclosure.
For a 200 amp service, it is recommended to use at least a 3/0 copper or 4/0 aluminum wire. These wire sizes can safely handle the current and provide necessary voltage drop considerations for a 200 amp service.
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.
No, a 1/0 copper wire size is not sufficient for a 200 amp service panel. For a 200 amp service panel, you would typically need to use 3/0 copper wire size for the service entrance cable. It is important to consult with a qualified electrician to ensure proper sizing and safety.
In a 200 amp service panel, the ground wire is typically a bare copper wire or green insulated wire. It is connected to the ground bar within the panel. Make sure to consult the manufacturer's instructions or a licensed electrician for guidance specific to your installation.

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.
AWG # 3/0 copper.
A 200 amp service panel with a 60 amp sub-panel.
200 amp service in chicago uses 3 aught.
Your service provider will give you that information The size will depend on: A) how close to the transformer are you. B) copper or aluminum C) Yes, you have a 400amp service but what will your actual peak amp usage be. D) Underground or overhead.
Depends on the size of the service. 100 amp service will require 3 gauge, 150 amp service will require 1/0 gauge, and 200 amp service will require 3/0 gauge.

50 mm or 2 inch will handle the 3/0 wires for a 200 amp service.
