DC/AC Voltage Classifications

DC/AC Voltage Classifications



Electricity is categorized as low, intermediate, or high voltage.
- Low voltage from 0 to 30-volts DC / 0 to 15-volts AC
- Intermediate voltage from 30-volts or greater to 60-volts DC / 15-volts or greater to 30-volts AC
- High voltage any voltage greater than 60-volts DC / 30-volts AC

Color coding is used to identify the different levels blue for intermediate voltage and orange for high voltage.

The Saturn VUE Green Line Hybrid falls within the intermediate range.

Two-mode hybrids and GM's Silverado and Sierra Parallel Hybrid Trucks are a combination of intermediate and high voltage systems (see chart footnote).







Even though the Saturn VUE Green Line Hybrid uses lower voltage than other hybrids you may encounter, it must still be approached with caution.
