In a system diagram scenario, when evidence shows utility power is present at the emergency generator while there is a reported loss of power, which bracket indicates the new area requiring inspection?

• A. Bracket #1
• B. Bracket #2
• C. Bracket #3
• D. Bracket #4

Answer: (B)

The important idea here is tracing how power flows from the source to the load and identifying where that flow could be interrupted after the generator is energized. If utility power is present at the emergency generator but the loads are reporting a loss of power, the problem isn’t upstream of the generator. The area to inspect is the point where generator power should be handed off to the rest of the system—the transfer switch and the generator feeder that connect the generator to the distribution path. That bracket marks the junction where power would move from the generator into the downstream circuits, so issues there (like a transfer switch not closing, blown contacts, or a damaged feeder) would explain why power isn’t reaching the loads even though the generator side is energized. Brackets that lie upstream of the generator or downstream of the transfer point don’t fit because they don’t address the path where generator power is supposed to enter the system for the loads.
