What does "hardwired" mean in electrical terms?

In electrical terms, "hardwired" refers to devices that are directly connected to the electrical system without using a plug or outlet. This means that the device is built into the wiring system of the building, providing a more permanent and reliable connection compared to portable appliances that plug into outlets. Hardwired devices, such as smoke detectors, security systems, and certain lighting fixtures, are designed for safety and function, ensuring they remain operational at all times without the risk of being disconnected inadvertently.

This method of wiring is often used in residential and commercial settings to ensure that critical systems remain powered without the potential hazards that may arise from loose or temporary connections. The permanence of a hardwired installation can also help to reduce the risk of electrical fires and improve the overall safety of the electrical system in a building.
