?What Is a Hot Electrical Wire

By Basil Argento

A hot electrical wire is an electrical wire with live electricity running through it. This is also known as a live wire. It is the opposite of a ground or neutral wire.
colour
A hot wire is typically, but not always, black or red. A wire of a different color should not be presumed neutral.
Detection
A hot wire can be detected with a voltage detector or a circuit tester.
Hazards
Working with live wires improperly can result in electrocution or death.
Precautions
Always ensure that the power is off at the breaker box before beginning any electrical work, and cover the box with a sign to let others know not to reconnect the power. Never stand in water while working.
Permits
In many states, a permit or special training is necessary to undertake any electrical work. Consider hiring a professional.
