Battery switch in Line voltage box

[davelectric]

Installing motion sensors in rest rooms. There is an existing 277 volt switch for overhead lighting. Customer bought nLight system with wireless switch and sensors.
Switch is battery powered RPODBA WH G2. Can you install a wireless battery powered switch in the same existing box with the 277 volt leads capped off or do I need to blank the 277 volt box off and install the battery switch next to it.

Good Question but I would think you need a way to isolate the live wires from the battery switch so it cannot be energized. I assume there is no ground terminal on the switch.

I would install the switch outside the box

Correct no ground and switch is all non metallic. Thanks for your input
