What is the term used for the device that can disconnect power in an emergency?

The term used for the device that can disconnect power in an emergency is "service disconnect." This device is typically located near the main entrance of the electrical service and is designed to provide a quick and safe way to cut off electrical power to a building or specific circuits. The primary purpose of the service disconnect is to ensure safety by allowing for immediate de-energization in case of an emergency, such as a fire or electrical hazard.

The service disconnect is essential for first responders and individuals needing to ensure safety while addressing electrical issues. It meets code requirements by making sure that the method for disconnection is both readily accessible and clearly marked.

Other options like the main breaker, although similar in function (because it also shuts off power), are typically part of a larger panel system rather than a standalone device. The distribution panel and load center refer to the organization of circuit breakers and connections within a building’s electrical system, and while they play roles in managing electrical distribution, they do not specifically refer to an emergency disconnect device.
