Final answer:
The question asks for the lighting feeder demand in volt-amperes, but critical data such as the wattage and quantity of lighting fixtures is missing to provide an accurate calculation.
Step-by-step explanation:
The question is about calculating the lighting feeder demand in volt-amperes for a warehouse with specific electrical service specifications.
However, there seems to be insufficient data in the question to provide a complete answer, as the power demand for lighting would typically depend on the wattage and quantity of the lighting fixtures installed, which are not provided in the question.
Generally, the formula to calculate the power demand in volt-amperes (VA) would be:
P (VA) = V (volts) × I (amps), where V is the voltage and I is the current.
Since the question is not including specific lighting power ratings or counts, it is not possible to accurately calculate the lighting feeder demand without this critical information.
