When the ERMS option is switched on, loads on the protected circuit automatically enter energy-saving mode.

When the ERMS option is switched on, loads on the protected circuit automatically enter energy-saving mode.

• A. True
• B. False
• C. Not specified
• D. Cannot be determined

Answer: (B)

Activating ERMS gives you the ability to manage energy use, but it does not automatically put every load on the protected circuit into energy-saving mode. Implementing energy-saving behavior typically requires a defined profile, schedule, or triggers that specify which loads can be shed and under what conditions. Without an active profile or control logic, loads stay in their normal operating state, and essential equipment may remain energized. So simply switching ERMS on does not guarantee automatic energy-saving across the circuit.
