At least 000 AWG copper or better yet, 0000 AWG copper. Another consideration is how far the 200 Amps are to be carried. Wire has resistance and 0000 copper has a resistance of .04901 Ohms per thousand feet. At 200 Amps, this means that over one thousand feet the voltage will be 9.8 Volts lower than at the starting point.
For a residential 200 amp service, it is recommended to use 3/0 copper or 250 MCM aluminum wire for the service entrance. Make sure to consult with a licensed electrician to ensure that the wire size meets local building codes and regulations.

Ground wire size for 200?
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.
What size wire for 200 amp service?
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.
What size wire is needed to feed a 125 amp sub panel from a 200 amp panel less than 200 wire feet away?
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.
Can you tap off of a 200 amp service for 2 100 amp panels?
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.
Is neutral wire same size as hot in 200 amp panel?
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.
What size wire for 25 amp service with a 200 foot run?
10 guage
Ground wire size for 200?
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.
Do you need to change the wire size going from 100 amp service to 150 amp service?
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.
What size wire and breaker do you need for a 200 amp continuous duty circuit?
AWG 2/0 copper wire.
What size neutral wire for 200 amp service panel?
AWG # 3/0 copper.
What size wire for 200 amp service?
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.
Does the ground wire to a 200 amp box have to be single strand?
No. Usually when you get to that size panels the grounds are stranded.
What size wire is needed to feed a 125 amp sub panel from a 200 amp panel less than 200 wire feet away?
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.

How do you know what size ground wire to use on a 200 amp service?
NEC code requires #6 bare copper.
What is the minimum service size for a 225amp residential service?
A 200 amp service panel with a 60 amp sub-panel.
