What is the standard mains voltage in Australia?

• A. 230 Volts
• B. 110 Volts
• C. 500 Volts
• D. 240 Volts

Answer: (A)

Power systems define a nominal voltage for designing and labeling electrical equipment, but the actual voltage you see can wander within a tolerance. In Australia, the official nominal mains voltage is 230 volts at 50 Hz. This value was adopted to align with international standards, so devices are typically designed to operate safely around 230 V, with real-world supply commonly ranging about 207 to 253 V due to ±10% tolerance. The older Australian standard was 240 V, and 110 V is used in other regions like the Americas, while 500 V is far above residential mains. So the best choice for the standard mains voltage in Australia is 230 volts.
