11. Explain three-phase electric power.
What You Need to Know
There are three phases of electric power, commonly referred to as single-phase, two-phase, and three-phase. Each phase carries a different voltage and is used for different applications. Single-phase power is typically used for residential and small commercial applications, while three-phase power is used for larger commercial and industrial applications. It is important to understand the different phases of electric power to properly select and install electrical equipment as a lineman. Three-phase electric power has three conductors carrying alternating currents of the same frequency. It is commonly used in industrial and commercial applications because it provides more power with less conductor material and lower voltages. This type of power is also more efficient and reliable than single-phase power, making it ideal for high-power electric motors and other heavy-duty equipment. The interviewer would like to see that you can easily explain the concept of three-phase electric power. Generally speaking, the easier someone can explain a concept, the better they understand it. Keep your answer concise and easy to understand.

Answer Example
"If I had to explain three-phase electric power, I would want to make sure my explanation was understood even by the layperson. Three-phase electric power has three waves of electricity that overlap each other. This allows for a safer, more reliable, and less expensive power solution for large businesses and manufacturers."
