What does it mean when a line is described as "hot"?

Explanation:
Hot means live. In electrical systems, lines can be energized or de-energized. Describing a line as hot tells you there is voltage on it and it can deliver a shock or an arc flash. This is why hot lines require protective gear and precautions and why you don’t touch them or assume they’re safe just because they’re near. This term does not mean the line is insulated for protection, nor that it’s scheduled for maintenance, nor that it’s de-energized. A line can be hot even without visible signs of trouble, so you treat it as dangerous until it’s verified de-energized with proper procedures.
