Wire size for 200 amp service?

The smart home and digital connectivity areFuturefor the owner. We need electrical panels that can handle the digital future, and many homeowners are upgrading their systems to 200 amp service.

Knowing the wire size for 200 amp service is essential to setting up your electrical system to work for years. But how do you choose among the options?

Quick response

Installing a 200 amp service requires a license and professional experience. Although you need a qualified electrician, it’s a good idea to know the basics beforehand.

For 200 amp service you will need:

  • #2/0 copper wire, or
  • #4/0 aluminum or copper-clad aluminum wire

There are a few things you’ll need to consider when choosing wiring, including personal preference, voltage drop, and wire length. Don’t worry – we’ll explain each of these in detail below.

What size wire do you need for 200A service.

The wire size you need for 200 amp service depends on the type of wire you receive. Consider the difference between copper wire and aluminum wire or copper clad aluminum wire. Next, we’ll cover the factors to consider when choosing your cabling.

Copper

Copper wiring is the best on the market. Its high conductivity, resistance to corrosion and heat and its versatility make it the ideal tool for wiring in all situations. However, copper can be more expensive and more complicated to install. Here’s everything you need to know about copper wiring:

  • High electrical conductivity: copper is a highly natural substance
  • conductive metal
  • . Only silver is a better conductor of electricity. Because it conducts electricity so well, you can use it over longer distances and you can use a much smaller gauge than aluminum.
  • Corrosion and Heat Resistance: Although copper changes color due to oxidation, these changes do not affect the performance of copper. Copper is corrosion resistant and will stand the test of time. It is also much more heat resistant than aluminum. Heat doesn’t cause it to expand or bend most of the time, so it stays put.
  • Flexibility: Since you can use thinner copper wires, it’s much easier to crimp and wrap without breaking.
  • As for distance: Again, since copper is very conductive and strong, it has better length and does not lose voltage over longer distances.

Again, copper is probably the best material for conductors, but it also has its downsides, which we’ll cover in the next section.

Short answer: When using 200 amp service, you will want

Aluminum

To illustrate what type of wire you need for a 200 amp service, a bundle of electrical cable spooled in a row

Aluminum is less conductive than copper and is also more susceptible to heat and corrosion. To compensate for the lack of conductivity, you also need a larger gauge, i.e. thicker wire.

However, most electricians prefer aluminum for several reasons. The disadvantage of copper is that it is expensive, heavy and more difficult to install. And that’s exactly why electricians often choose to use aluminum.

Here are the main advantages of using aluminum wiring:

  • Easier Installation: Aluminum is much lighter than copper – even when you factor in the heavier gauge required for good conductivity. Because it is so light, aluminum is quick and easy to install. If you want to get the job done quickly, aluminum is the way to go.
  • Cheaper: In short, aluminum is more affordable than copper. It works well and doesn’t break the bank.

Short answer: For 200 amp service, you will need a

Copper Clad Aluminum

Copper clad aluminum is your third option and offers some of the benefits of the previous two options. Compare it with the other two.

  • Cheaper but not the cheapest: Copper clad aluminum is more affordable than pure copper but more expensive than aluminum.
  • More corrosion resistance than aluminum: copper coated aluminum wire protects aluminum from corrosion. Most aluminum requires an anti-oxidation coating connected to the power connector, but copper clad aluminum does not.
  • Good conductivity: Again, copper-clad aluminum falls slightly in between the other two in terms of electrical conductivity.

Short answer: As with aluminum, you will need a

Other Factors to Consider

Before making a final decision, you need to consider a few other factors.

  • Voltage Drop: Your circuit breaker voltage should be 120 volts. A voltage drop means that power is lost as it travels along the wires to your devices and appliances. You can improve your voltage drop by increasing the measurement of your leads.
  • Distance: Regarding voltage drop, if you need power over a distance of more than 50 feet, you will probably need copper wire. A
  • Local building codes: Make sure you are familiar with the electrical codes in your area by consulting your National Electrical Code (NEC). You should also make sure you have all the necessary permits for this type of work.

Explore our answers to some of the most frequently asked questions about wire size for 200 amp service.

How much does it cost to install a 200 amp electrical service?

Most of us are just looking to upgrade our 100 to 150 amp service. Upgrades to a 200 amp electrical service installation cost between $750 and $2,000. The range depends on how much wire you need, how much leveling, etc. However, a full reset with a new circuit breaker can cost up to $4,500.

Can I run a 200 amp sub-panel from a 200 amp main panel?

Although you could technically do it, we recommend looking at the 400A service. Check the overall power consumption to make sure the side panel isn’t using most of the power for just one or two applications.

Steps:

1. Have utility company to disconnect electrical cables from the house.

2. Remove the glass meter from the meter socket.

3. Unscrew meter socket from side of house, then use cable cutters to sever the cable connected to the socket.

4. Enlarge existing cable hole in wall using a cordless drill and 3-inch-diameter hole saw.

5. Bore through the rim joist using an extension shaft and 2-inch-diameter hole saw.

6. Attach a length of 200-amp SE electrical cable to the new meter socket.

7. Feed the SE cable through the hole in the wall and then screw the meter socket to the exterior of the house. Use a torpedo level to ensure the socket is level.

8. Install the new PVC weather head and conduit to the exterior wall, directly above the meter socket. Secure the conduit to the meter socket using PVC cement. Fasten the conduit to the house with U-shaped plastic clips.

9. Have the utility company mark the locations of any underground lines. Then, pound two copper ground rods into the ground using a 3-pound sledgehammer. Space the rods 6 feet apart.

10. Make the wire connections between the ground rods, up to an inter-system bonding termination, and into the meter socket.

11. Connect the power wires to the meter socket.

12. Plug the glass meter into the meter socket. Then, snap on the meter cover.

2. Unscrew and remove old electrical panel from the wall.

3. Screw a large ¾-inch-thick plywood panel to the wall for mounting the new electrical panel. 4. Feed the SE cable through the top of the new electrical panel, then screw the panel to the plywood. Use a torpedo level to ensure the panel is level.

5. Make all the electrical connections inside the electrical panel.

6. Feed the house circuits into the panel, making sure each cable passes through a cable connector.

7. Connect the bare-copper ground wires and white-insulated wires to the ground and neutral bar inside the panel.

8. Plug new circuit breakers into the bus bar.

9. Run the main ground wire from the bottom of the electrical panel to the copper water main.

10. Have the utility company reconnect the electrical cables to the exterior of the house.

11. Label each breaker with the correct house circuit.
