The plan shows AC-1 around the corner from its only disconnect. What is needed at the equipment?
- AAn extension cord
- A properly rated located disconnect
- CA thermostat only
- DA panel directory in another building
Why B is correct
Service personnel need a local means to isolate the equipment; control circuits and remote documentation do not provide equivalent disconnection. The best answer is therefore “A properly rated disconnect at the required location.” The other choices either address a different system, rely on an unsafe shortcut, or make a conclusion not supported by the stated facts.
