Identify the circuit and switch off the power to the wall. Unscrew faceplates, disconnect wires, and remove outlets or switches. Removing an old electrical box from a wall can be a daunting task. Even if you're confident in your DIY skills, you should always consult a professional electrician. I show how I took off the original electrical box, referred to as new work electrical box, from a wall so I could upgrade it to a double gang old work box to handle an additional switch for the fan in the bathroom.

[pdf] The article provides an overview of protective relaying principles and their applications for high-voltage power system components. It covers the protection methods for generators, transformers, buses, and transmission lines using various relay types to detect and isolate faults efficiently. Ensure fast, selective fault clearance per IEC/IEEE standards. Long term cost reduction (TCO) for trainings and maintenance by reduce variety of relays A fast and selective arc fault mitigation for air-insulated LV & MV switchgear and Relion protection and control relays and sensor. Core idea: Protective relays monitor electrical quantities and command protective devices to isolate faults or abnormal operating conditions.
