Homonym: hot wire (Bypass)
A "hot wire" refers to a wire that carries electrical current and is typically connected to a power source. It is often used in electrical systems to deliver energy to devices or appliances. In many cases, the hot wire is color-coded, commonly in black or red, to distinguish it from other wires, such as the neutral or ground wires.
In safety contexts, touching a hot wire can lead to electric shock or fire hazards. Therefore, it is crucial to handle electrical wiring with care and to ensure that power is turned off before working on any electrical system. Proper knowledge of wiring, including the role of the neutral wire and ground wire, is essential for safe electrical practices.
