For how many instances does Article 225 specify that multiple disconnecting means can be used for outside feeders?

• A. Only one instance
• B. Two instances
• C. As many as required but must follow specific guidelines
• D. Not allowed at all

Answer: (C)

Article 225 of the National Electrical Code addresses the requirements for overhead and underground service conductors and feeders that are installed outside. It specifies guidelines for disconnecting means, allowing for multiple disconnects under certain conditions. The correct answer reflects the provision that allows for as many disconnecting means as required, as long as they meet specific guidelines outlined in the Code. This is particularly important in scenarios where a single disconnect might not be practical or sufficient for the system in place. The guidelines ensure that the installation maintains safety and facilitates maintenance and operation of the electrical system. This flexibility is essential for accommodating various configurations of electrical installations, such as those involving multiple buildings, structures, or when feeders are routed over different areas. Code specifications related to the placement, accessibility, simultaneous operation compatibility, and markings of these disconnects are critical to ensure they can be utilized effectively without compromising safety. The other choices imply limitations or prohibitions that do not align with the provisions of Article 225, which emphasizes the need for safe and practical designs in electrical installations.
