A 200 amp organization needs a wire size of either 2 AWG or kcmil Copper wiring or 4 AWG or kcmil Aluminum or Aluminum clad wiring because that the cabling to it is in installed. The voltage drop and also length the the wiring are factors in identify which wire to use. Aluminum wiring demands larger size wires 보다 copper wiring as result of its weaker conductivity than copper.
You are watching: What size wire for 200 amp
For a 200-amp electrical service, what dimension wire is required?
When creating a 200 amp power line, it’s an important to use the ideal gauge wire. To finish the skilled installation, you’ll need a permit. Permits deserve to still be derived by homeowners in numerous regions. Examine with the local real estate authority to watch if friend can acquire the permit yourself or if you’ll need to hire one electrician.
Inside a 3′′ conduit, a 200 amp electric company requires #2/0 AWG copper cable or #4/0 AWG aluminum or copper-clad wire. A 200 amp structured wiring is not a do-it-yourself project. It typically necessitates obtaining a permit and having a skilled electrician install it follow to local electric codes.
The main electrical panel is positioned in an underground garage, basement, or inner room. Strength is derived from the electric service lines and also flows via the exterior electric meter base and also then right into the primary digital circuit.
Sizes of cable for a 200 Amp Service
The American cable Gauge (AWG) is the conventional for gauging electrical wiring in the united States.
Wiring a 200-amp service requires #2/0 copper, #4/0 aluminum, or aluminum covering wiring. The voltage difference and also lengths that the wiring dictate which cable is utilized.
The adhering to table shows, length and voltage ns of wiring:
The usage of #4/0 aluminum or copper-clad cable is widespread among electrical contractors. Because copper is more resistant to warm than aluminum, you’ll need a #2/0 AWG copper cable frequently used for electric wiring. Copper wire does not rust and also is oxidation resistant.
#4/0 AWG aluminum wiring is compelled for aluminum or copper-clad aluminum wiring. Due to the fact that aluminum has a poorer conductivity than copper, it necessitates a bigger cable size. To stop corrosion, aluminum wiring calls for an oxidative coating in ~ the connecting terminals. In ~ the link terminals, copper-clad aluminum go not need an antioxidant coating.
Aluminum wiring is commonly used because it is much less expensive, lighter, and an ext elastic 보다 copper, in spite of copper gift a much better conductor.
Why Is Copper Wiring Used?
When it comes to wiring, copper is favored. Copper wire has several advantages, including:
The cable strands space thinner due to the fact that copper is extremely conducting, enabling the cable to bend easily without breaking.
Why usage Copper-Clad Aluminum wire or Aluminum Wire?
For a range of reasons, aluminum wire is wanted for organization entry wire, including:
The length of time the company wire has been in use
Consider just how long the company cable will certainly go from the meter come the electrical box as soon as considering cable size. The most significant voltage fall (which we will certainly cover momentarily) is 3%. The potential distinction will often determine even if it is copper or aluminum wire have the right to be used and the gauge required.
|copper #2/0 wire||50 feet|
|copper #3/0 wire||100 feet|
|copper #4/0 wire||150 feet|
|aluminum #4/0 wire||50 feet|
|300 kcmil aluminum||100 feet|
Distances might differ relying on where girlfriend are. For more information, call your local building department.
Wire made of aluminum and also copper is authorized for 200 amps that service. On the other hand, the aluminum gauge will certainly be higher due come a reduced conductivity and heat resistance. Copper wire have the right to be used over a greater distance.
