However, industries may use a different source voltage. In the United States and Canada, the standard source voltage is 120V. Household and industrial source voltages may differ from one location to the next. Keep the source voltage in mind when expanding your electric circuit. You can use 1/0 AWG Copper wire or 3/0 AWG Aluminum wire for a three-phase power source. We recommend either 2/0 AWG copper wire or 4/0 AWG aluminum wire for single-phase. Both have distinct characteristics, but you must choose the best suits your requirements. Copper, however, comes at a higher price.Īluminum is lightweight and flexible, making it easier to work with. What Size Wire Do I Need To Run 150 Feet?Īluminum has a lower conductivity than copper. (Read Light Bulb Socket Sizes Chart)īy the end, you’ll know more about laying an underground service, the power quality issues you may face, and why sometimes, it is wise to use a licensed electrician. In our guide, you can find out more about using the right wire gauge that meets your 100 amp wire size needs. However, it fluctuates depending on the source voltage.

The average voltage drop for these lines should be 3%. If you have three-phase circuits, use 1/0 AWG Copper wire or 3/0 AWG Aluminum wire. For example, the conductor type, voltage for your source, minimum voltage drop, circuit installation method, phase count, and so on.Īs an example, for single-phase circuits, use 2/0 AWG copper wire or 4/0 AWG aluminum wire. Therefore, before selecting a wire-management system, you should know a few crucial considerations, especially for electricity entering via the service entrance of your home. This is especially true if you are unfamiliar with electrical equipment and calculations. Picking 12-2 wiring for lights is similar. What size wire for 100 amp service 150 feet distance is often asked.Ĭhoosing the correct wire size for your amp might be a pain.

If you don’t pick the correct wire for the job, you could end up with an enormous mess. The size varies depending on your needs and the situation. Wires are available in a variety of shapes and sizes.
