Square D makes the following recommendation for LV switchgear and MCC's with doors closed: "These components can be operated with the use of PPE 0
under normal circumstances. (See definition of normal
circumstances preceding this table.)"

"Definition of “Normal Circumstances” As used in the table, this term describes equipment that has been:
• properly installed, rated, and maintained;
• properly commissioned and tested after installation;
• in operation, under load, for some period of time."

For safety switches they reccomend:"PPE should be worn per the incident energy level determined at that point in the system"
