Is there a PPE requirement for inserting / removing 240 v or 480 v plugs?
Hello Kurt, your have asked a very good question but a bit more information would be needed to provide you with a proper response. I would assume that you are are referring to working with energized circuits, welding plugs and oilfield equipment come to my mind. An electrical hazard risk assessment should be performed to identify all of the potential hazards. The priority should always be to de-energize prior the connecting plug and cord equipment. If the task must be done while energized the proper PPE would be determined by the extent of the workers exposure. The exposure, risk, and PPE requirements could vary greatly from one situation to the next. If you are looking for and easy answer, it would be " Turn it off".
Many times I have seen workers connect plug and receptacle equipment with the receptacle energized and a fault occur due to loose or improper connections, moisture in the equipment, unexpected load starting, or energizing damaged cables. Many injuries and fatalities occur due to this very action.
PPE is always a last resort solution when dealing with electrical hazards.
I agree with Steve, especially with 480V Receptacles we always specify a disconnect/receptacle combo that does not allow the plug to be inserted or removed until the circuit is de-energized. Removes human error from the equation. De-energized equipment requires no additional PPE requirements.
