Which statement correctly describes the grouping requirement for the six disconnects?

• A. They must be grouped and marked to show the load served
• B. They must be left ungrouped but labeled
• C. They must be color-coded only
• D. They must be fused together

Answer: (A)

When multiple disconnects serve a limited-energy system, they must be grouped and marked to show the load served. This setup keeps the disconnects physically together for easy operation while clearly identifying which piece of equipment or circuit each switch controls. The labeling makes it immediately evident what will be de-energized if you operate a particular disconnect, which is crucial for safe maintenance, testing, and emergency response. Relying on color alone or labeling without grouping doesn’t provide the quick, unambiguous identification needed. Fusing the disconnects together would defeat the purpose of having separate controls for individual loads.
