Multiple Choice

The portion of the electrical system that is distribution will operate at:

Distribution carries power from substations to customers, using medium-voltage lines that are stepped down for final service. The voltages on these distribution feeders are typically in the range of about 2,000 to 34,500 volts. This range is high enough for efficient local transmission and reliable equipment, yet low enough to be safely transformed down to customer service voltages (like 120/240 V) before it reaches homes and businesses. That’s why the distribution portion is described as operating from roughly 2,000 V up to 34,500 V. Transmission lines, on the other hand, run at much higher voltages (tens or hundreds of kilovolts), and very low voltages (like 600 V) are closer to the service or low-voltage side rather than the main distribution network.
