I am setting up a small rack panel and I'm mounting it to 1" ply on a piano hinge to make it easier to get behind.
I'd like to attach the electrical box on the same board. This means that the electric box could move but it won't be very often.
I was thinking I would use a stranded whip to connect the one on the board to a stationary box nearby.
Can I mount an electrical box to something that moves? In CA, USA.
