Carbon dioxide does not conduct electricity and can be used on electrical fires. In theory, if you had some kind of metal fire ("Class D") that was electrically energized, you would not want to use it (carbon dioxide will chemically react with most, if not all, burning metals and will make the fire worse).

I think I would be concerned about the use of CO2 to fight an electrical fire if any of the following conditions existed:
1. You had to fight the fire in a confined space and build-up of discharging CO2 gas could pose an asphyxiation risk.
2. If a large amount of other burning materials were present that CO2 is not rated to extinguish. Like class "A" or "D" materials as others have mentioned.
3. If the fire was too large to fight with a portable unit. Fire extinguihsers are designed to extinguish small fires, if the fire is too large, or you cannot fight the fire with your back to your exit, then do not take the chance.
That's my take.

In a confined space it can be dangerous if you do not have breathing apparatus.
The CO2 smothers the fire by cutting off the oxygen.
