D. Current, voltage, frequency and short time current
Answer: Option D
Solution(By Examveda Team)
A bus-bar is rated based on current, voltage, frequency, and short time current.Current: The maximum amount of current the bus-bar can carry without overheating.
Voltage: The highest voltage the bus-bar can handle safely without breakdown.
Frequency: The frequency of the alternating current (AC) the bus-bar can operate with.
Short time current: The maximum short-circuit current the bus-bar can withstand for a brief period without damage.
These ratings ensure the bus-bar operates safely and efficiently within its designed parameters.
