It’s more cost-effective, lightweight, and flexible than copper, which makes it a widely appealing choice.īoth professional electricians and homeowners tend to favor copper wiring, especially for branch circuits. However, this isn’t a requirement for copper-clad aluminum wiring at the connection terminals.ĭespite copper being recognized as a better conductor, aluminum wiring is quite popular.

One key factor to consider with aluminum wiring is requiring an antioxidant coating at the connection terminals to fend off corrosion. Aluminum wiring requires a larger diameter wire since its conductivity is lower than copper’s. You’ll need a #4/0 AWG 200 amp wire size if you’re considering aluminum or copper-clad aluminum wiring. Copper has excellent conductivity, is resistant to rust, and doesn’t oxidize, adding to its appeal. This type of wire is a popular choice for electrical wiring, mainly due to its superior heat resistance compared to aluminum wires. You will require a #2/0 AWG copper wire if you’re going the copper conductor route. Many electrical contractors opt for #4/0 aluminum or copper-clad wire when dealing with a 200 amp wire size.

The power flows from the utility service entrance conductors through the outdoor electrical meter base and into the main electrical panel, which is typically located in an attached garage, basement, or interior room. Additionally, the installation should be carried out by a qualified electrician who adheres to the local electric codes. When undertaking a 200-amp service wiring project, it is essential to obtain an electrical permit. Familiarizing yourself with the applicable electrical codes will help you select the appropriate wire size for your 200 amp service. It is crucial to ensure that your chosen 200 amp wire size can handle the high current demands of your system while meeting safety standards. However, for underground 200 amp services, a 250 KCMIL aluminum wire with a 255A ampacity is typically preferred, as it fulfills the minimum requirement of 250A. Licensed electricians often choose 4/0 AWG aluminum wire for long distances to mitigate the high costs of copper. However, if you are running three wires within the same conduit, you can opt for a larger conduit size of 2 or 2.5 inches.

Choosing a Wire Size for 200 Amp Serviceįor underground installations of a 200 amp wire, it is advisable to use a PVC conduit of at least 1.5 inches in schedule 40 or 80. For more information, please refer to the table below. When installing a 200 amp wire over a distance of 200 feet, it is recommended to use a wire size of 500 kcmil for copper or 1000 kcmil for aluminum. However, if you require a 200 amp feeder wire for longer distances, the NEC recommends increasing the wire size by 20% per 100 feet from the circuit breaker panels.

The significance of choosing the right 200 amp wire size cannot be emphasized enough.Īccording to the NEC Table 310.12 guidelines, for a 200 amp service, it is advised to use either a #2/0 AWG copper wire or a #4/0 AWG aluminum wire for distances up to 50 feet. Selecting the appropriate wire size for a 200 amp service wire installation is crucial when embarking on a new electrical service project in a residential property.
