Hanging wall fixture for vanity

I am looking to install wall lights above a vanity and I am struggling a bit with the code… working under 2017 NEC.

Simple question to start: Does the fixture have to hang from the box or is having it grounded to the box and hung from the wall sufficient?

A box just in the wall is not grounded so you can not ground to it. Your cable should have a hot (black), neutral (white) and a bare copper ground so there shouldn't be any need to ground to a box and most fixtures come with a grounding pigtail you can attach to your bare copper ground.

Thanks Dane,

What I was thinking was that all the connections would be made in the metallic wall box, so the box would be properly grounded. I am unclear if the fixture needs to hang from the box or can the wall support it.

Hi, if you have the box installed why would you not want to hang the fixture from it?

Many fixtures come with a mounting plate that secures to the box.

There's no specific reason it has to hang from the box. Chain type chandeliers are often hung from a hook in the ceiling, then looped over to the box.

There are two styles of fixtures..... whether wall or ceiling mount.

One style comes with a back plate that has a knockout or two in it. With this style you can bring the wire directly into the fixture. The back plate mounts to the wall. It gets grounded and the fixture attaches to the back plate.

The other style of fixture has a canopy or wiring cover but the back is open. This type of fixture requires a box to connect to. This type fixture also comes with a fixture bar to mount the light to the box.
