What is the purpose of cover-up around exposed energized parts, and where is it required?

To prevent accidental contact and to insulate exposure.

To color-code energized parts.

To prevent accidental contact and to insulate exposure; required wherever workers could contact live parts.

Cover-up around exposed energized parts provides a protective barrier that prevents accidental contact with live conductors and adds insulation to exposed surfaces, reducing the risk of shock or arc-flash injuries. It is required wherever workers could contact live parts, such as around switches, disconnects, transformers, and other energized equipment, during operation or maintenance. While color coding helps identify parts and voltage-drop calculations are unrelated to protection, the primary purpose of cover-up is to keep workers from touching energized parts and to insulate them.

To guide voltage drop calculations.
