Do some ballast require 220 volts?

Do some ballast require 220 volts?

• A. Yes
• B. No
• C. Only at 110 Volts
• D. Only at 240 Volts

Answer: (A)

Electric ballasts are built for the voltage of the power supply they’re connected to. Some ballast models are designed to operate specifically at higher line voltages, like 220–240 V, which is common in many regions outside North America. When a ballast is rated for that voltage, it will start and regulate current correctly only if the supply falls within its rated range. So yes, some ballast require 220 volts to operate properly. Always check the ballast label for its input voltage range and use one rated for your local mains.
