The costs of installing a 200 amp service is not cheap. You will be spending anywhere from $1,500 to $3,000 for a 2,600 square foot home. The cost will depend on the type of wire you use, whether it be copper or aluminum.
What conductors are used for underground 200 amp service?
An underground 200 amp service has a couple of different options, depending on what type of wire you plan on running. You can choose between copper conductors and aluminum conductors. Copper is the most common conductor for wiring. It works so well because it has less resistivity than other metals.
Why is copper wire so good?
It works so well because it has less resistivity than other metals. Copper also oxidates less and does not rust. It does produce a green patina, but in the case of copper, it helps protect the metal from further erosion. For copper wiring with a 200 amp service, you will need to use #4 AWG copper wire.
How long has copper wire been used?

It is recommended by the National Electrical Code (NEC) to use a maximum voltage drop of 3 percent for individual household circuits, or branch circuits. This number is also a good guide for sizing the conductors for an underground run.
Why do you need to increase the size of the wire?
However, if the cable run is particularly long, as is the case with most underground runs, you may need to increase the size of the wire to compensate for voltage drop. Voltage drop refers to a loss of voltage in the circuit from the natural resistance of the wires.

How many wires are needed for a three phase circuit?
For three-phase circuits, four wires are required. One of these wires is a ground wire which can be sized down. To calculate ground wire size, use the Ground Wire Size Calculator. Insulation - Select the thermal rating of the insulation on the wire. Conductor - Choose the material used as a conductor in the wire.
What determines the ampacity of a wire?
However, many different external factors such as ambient temperature and conductor insulation play a part in determining the ampacity of a wire. Wire ampacity is calculated in such a way as to not exceed a certain temperature rise at a particular electrical load.
What is the purpose of sizing electrical wire?
The National Electrical Code provides requirements for sizing electrical wire to prevent overheating, fire and other dangerous conditions. Properly sizing wire for many different applications can become complex and overwhelming. Amperage is the measure of electrical current flowing through a circuit. The ampacity rating of a wire determines the amperage that a wire can safely handle. In order to properly size a wire for your application, the ampacity ratings for a wire must be understood. However, many different external factors such as ambient temperature and conductor insulation play a part in determining the ampacity of a wire.
Why should I use good judgement when sizing conductors?
Good judgement should be used when sizing conductors because large conductors can become costly and difficult to install, while small conductors can cause potential danger . Use the calculator above to size wire for basic applications, or view some of the wire ampacity charts for wire ampacity values.
How does the cross section of a conductor affect the resistance of a wire?
However, the cross-sectional area of a conductor can also be changed to alter the conductor's resistance. By increasing the cross-section of the conductor (or increasing the size of the wire), the resistance decreases, and the allowable ampacity increases .
What is the difference between a single phase and a three phase circuit?
Single-phase voltages are usually 115V or 120V, while three-phase voltages are typically 208V, 230V or 480V. Amperes - Enter the maximum current in amps that will flow through the circuit. For motors, it is recommended to multiply the nameplate FLA by 1.25 for wire sizing.
What are the different types of electric motors?
There are many different types of electric motors ranging from single-phase to three-phase AC motors, low and high voltage DC motors, synchronous and asynchronous motors. When designing a feeder or branch circuit with one or more electric motors, there are several important things to account for.
How many amps does 1000 kcmil wire have?

What is voltage drop across a wire?
Voltage drop across a wire is proportional to the current flow and wire resistance; for AC power such as your service entry cable (SEC) total impedance and power factor (the ratio of power loss) are considered too.
Can 200A wire fit in 400 foot wire?
Watch out: with a 400 foot run your 200A wire size may be so big that it will not fit in the standard wiring lugs in your 200A panel. Your electrical supplier an provide a wire size reducer that can make the connection between a larger diameter SEC wire and the lugs in your electrical panel.
