Where must the service disconnecting means be located if actuated by a remote control device?

The correct answer is that the service disconnecting means must be located at a readily accessible location when actuated by a remote control device. This requirement ensures that individuals can quickly and easily access the disconnecting means in the event of an emergency or when maintenance is needed. Accessibility is critical because it allows for prompt action in situations such as power restoration, service interruptions, or safety concerns, making it vital for both safety and operational efficiency.

While the other options might seem plausible in certain contexts, they do not align with the necessary accessibility requirements outlined by NEC. For example, a locked area would hinder quick access, which is counterproductive in emergency situations. The requirement to be near the service meter may not guarantee accessibility, especially if the meter is located in an inconvenient or less accessible position. Likewise, being within sight of the main panel does not necessarily ensure that the disconnecting means can be reached quickly, especially if located at a distance or in an obstructed area.

Overall, the emphasis on a readily accessible location plays a crucial role in ensuring safety and compliance with electrical codes, allowing for swift operation of the disconnecting means when needed.
