What size wire for 200 amp service is a common question electricians get asked. The answer depends on the type of system being installed, the length of the run, and the number of circuits required. For most homes, 4/0 AWG copper wire is sufficient to handle the load.
This wire can be run up to 400 feet without any problems. If there are more than two circuits required or if the home is larger than 4,000 square feet, then 6/0 AWG copper wire may be necessary.
If you’re planning on installing a 200 amp service, you’ll need to use 4 AWG copper wire. This size wire is capable of carrying up to 65 amps, which is more than enough for a 200 amp service. Just make sure that the wire is rated for use in underground applications.
What Size Copper Wire Do You Need for 200 Amp Service?
Copper wire is an essential part of any electrical system. It is used to conduct electricity and has a wide range of applications in the home, office and industrial settings. When it comes to sizing copper wire for use in your electrical system, there are a few things you need to take into account.
The first is the amperage rating of your system. This will determine the size of copper wire you need for 200 amp service. The second factor is the voltage rating of your system.
This will also affect the size of copper wire you need. In general, you will need a minimum of 10 AWG (American Wire Gauge) copper wire for a 200 amp electrical system. However, this may vary depending on the specific application and voltage rating of your system.
For example, if you are using 12 AWG copper wire in a 240 volt circuit, then you can use 8 AWG copper wire in a 208 volt circuit with no problems whatsoever. Conversely, if you are using 14 AWG copper wire in a 120 volt circuit, then you would only be able to use 10 AWG copper wire in a 100 volt circuit without overloading it.
How Many Wires Do I Need for a 200 Amp Service?
In order to have a 200 amp service, you need 4 wires. Two of these wires are the live or “hot” wires, and the other two are neutral. The hot wires carry the electricity to your home, while the neutrals return any unused electricity back to the power grid.
To get a 200 amp service, you’ll need at least #4 AWG copper wire or #2 AWG aluminum wire.

200 Amp Service Wire Size Chart
If you’re planning on upgrading your home’s electrical service to 200 amps, you’ll need to know what size wire to use. The size of the wire is determined by the amount of current it can carry and the distance it needs to travel.
For a 200 amp service, 8 gauge copper wire is typically used.
This type of wire can carry up to 65amps over a distance of 30 feet without exceeding its temperature rating. If your home is further than 30 feet from the power source, you may need to use a larger gauge wire. Keep in mind that the amperage rating of your electrical panel will determine how many breakers or fuses you can have.
Most 200 amp panels have room for 24 breakers or fuses. They also have space for two main circuit breakers, which are required by law in most jurisdictions.
If you’re wondering what size wire you need for a 200 amp service, the answer is 4 AWG copper. This type of wire is typically used in residential and commercial applications, and it can be used for both underground and overhead installations.
