What type of harness has wires with thinner insulation?

Explanation:
Understanding how harness insulation levels vary helps explain this. A protected harness uses conductors with insulation that is thinner than standard so you can fit more wires into the same harness space. The outer jacket then provides the necessary protection from the environment and abrasion. Shielded refers to an EMI shield around the conductors, not insulation thickness; grounded relates to a return path to the aircraft structure, and uninsulated means there is no insulation at all. So, the type with thinner insulation is the protected harness.
