Wafer Light Rough-in Plate

[Jimmy7]

The majority of our work is service work in older homes. Lately I have been doing some new work where we are installing wafer lights. As a result, we are installing metal rough in plates for the wafer lights. Yesterday we were talking about the rough-in plates on the job site, and wondering if they should be grounded, or even it is a concern. They don’t really even make contact, and they’re just used to make sure the light lands up in the correct place.

Are they likely to become energized?

I highly doubt it

We don't bond every nail, screw, and truss plate either.

There you go. Answered it yourself.

Technically a lot of them have a nut or clip to hold the junction box and so it should be bonded a little through that connection.

Technically I'd guess you are supposed to use that nut or clip to hold the driver box as well.

I've used the Halo type and they have two studs to mount the box to the plate so it is grounded. If the box isn't attached to the plate do you just throw it up into the ceiling?

I been using Juno/Lithonia type and they have two screws with a rubber(?) washer for studs. I suppose the washer is intended to help keep the screw from falling out of the plate yet not have to back the screw out to install the box to it. Many those screws fall out anyway before you even open the package. Only time I have actually mounted the box on it is if I wanted to install the box during rough in stage - which usually is maybe for harder to get to places after walls/ceilings are finished like over a stairwell. Then all you need to do is connect the low voltage plug and push the wafer in the hole at finish time. I do tape the low voltage plug or else who knows what I may find after drywall/painters are done.
