It’s an issue of safety when it comes to selecting the correct wire for a 200 amp service. The wire you use for 200 amp service depends on the material, and if it’s aluminum, you’ll need 4/0 wire. Let’s look at what size wire you’ll need for 200 amp service, whether it’s copper, copper-clad, or aluminum.
If you’re installing a 200-amp subterranean service, you might be asking what size wire for 200 amp service underground. We’ll answer that for you, but keep in mind that you may require a permit and that the installation should be done by an expert.

For a 200 amp service, you’ll need 4/0 aluminum and 2/0 copper wiring. The National Electrical Code (NEC) advises that you keep voltage drops to a maximum of 3% per circuit. Check your local electrical codes before deciding on what size wire for 200 amp service underground because codes differ by state and municipality.
If you are unfamiliar with all of the standards, codes, and permit procedures, electrical work can be a difficult task. To begin, find out what codes and permissions are required in your region.
What size wire for 200 amp service underground wiring
Depending on what size wire for 200 amp service underground you wish to run, an underground 200 amp service has a few distinct alternatives. Copper conductors and aluminum conductors are available.
Copper is the most popular wiring conductor. Because it has a lower resistance than other metals, it performs so well. Copper also has a lower oxidation rate and does not rust. It does develop a green patina, but in the case of copper, it aids in the protection of the metal from further deterioration.
Aluminum, or copper-clad aluminum, is the next best option for a 200 amp service. Aluminum wiring has a lower conductivity than copper, so bear that in mind if you’re going to use it. You’ll need 4 AWG aluminum wires to use aluminum with a 200 amp service.
Copper Conductors are used in this project.
If your budget allows, copper conductors are recommended. For a variety of reasons, copper is preferable to aluminum. For almost 200 years, it has been the most extensively used type of wire and has been shown to be durable.
If your home has a high load capacity, copper will ensure that everything it runs will be able to withstand the 200 amp service you are installing. Do not be concerned about what size wire for 200 amp service underground about the copper wire turning black. Copper wires naturally tarnish as a result of the oxidation process.
Using copper-clad aluminum or aluminum
If you’re on a budget, aluminum will suffice. It is less expensive than copper, but it does not carry electricity as well, making it less suitable for homes with high load capacities. As a result, if you’re going to use aluminum, copper-clad aluminum is the way to go.
It improves the conductivity of aluminum and prevents it from corroding as much. You’ll spend a little extra money, but you’ll be glad you did.
What’s the total length of wire you’re using & What size wire for 200 amp service underground Wiring
You’ll also need to think about how much wire you’ll be running. This could be a deciding factor in whether copper or aluminum wire is used.
Although both wires are rated for 200 amp service, copper can be used over greater distances. This is due to the fact that it conducts electricity better and does not expand and compress as much as aluminum.
Aluminum can obstruct the flow of electricity over long distances. If you’re going to think again about what size wire for 200 amp service underground uses aluminum, there are some safeguards you may take, such as utilizing copper-clad metal and special copper fittings on the ends of the aluminum wire.
