Hello,
Article 130.3(C) states that equipment shall be field marked with a label containing the available incident energy or required level of PPE.
What is meant by equipment? Where is the line drawn? Is this only for equipment that may be serviced or tested while energized? For example, should the motor terminal box be labeled?

I don't label motor conduit boxes. There are no exposed parts inside and the only way to make them exposed is to dismantle them while the motor is running. I generally restrict the labels to devices that routine are serviced live like MCCs, swithgear, breaker panels, and cabinets that have live parts. But I also have not been labelling Safety switches or fused switch disconnects. The FSD may need to be label as someone could be changing fuses, not sure about the safety switch.

I don't label motor terminal boxes either. I do label disconnects, however. The thought being fuses may be replaced in the disconnect with the line side energized. This may also be the last device switched after maintenance, and so will likely be the device that sees the fault if something went wrong.

Labeling
We have been recommending that companies label any piece of apparatus that they will be working live on. Remember - troubleshooting is working live (voltage testing), it is just exempt from the permit.

NEC 110.16 explains what needs to be labeled.
