Final answer:
A power limited class 1 circuit may operate at a maximum of 30V, 1000VA. This complies with safety standards that restrict continuous use to prevent overloading and potential hazards.
Step-by-step explanation:
A power limited class 1 circuit may operate at a maximum of 30V, 1000VA. The options provided indicate different voltage and power specifications, and the correct option here is B. 30V, 1000VA. This reflects the safety standards in place to prevent excessive heat or fire risk due to overloading electrical circuits. According to typical safety regulations, continuous use is limited to 80% of the breaker current capacity to ensure a safety margin is maintained.
