I agree especially with two layers of 5/8 rock.Four 1/4-20 toggle bolts will hold quite a bit of weight.
Even if you use strut you would still toggle bolt the strut to the wall.

Holding the weight wouldn't be the issue, it would be the designs fire resistive ability being compromised.I agree especially with two layers of 5/8 rock.

Would it not be better to lag the strut into studs? Faster than toggle bolts. Not sure if this would work with steel studsI agree especially with two layers of 5/8 rock.

The one's I've used are 75# a piece IIRC.Four 1/4-20 toggle bolts will hold quite a bit of weight.
Togglers. Much better than toggle boltsI have used these for hanging TVs on steel-stud walls. A small hole-saw makes perfect holes through the steel stud.

Back when I was working as a tech, I tried these without much success. There might be a knack that I didn't have.I have used these for hanging TVs on steel-stud walls. A small hole-saw makes perfect holes through the steel stud.

There are good ones and bad ones. The good ones work really well. The bad (cheap) ones' plastic pieces are brittle and will snap, rendering the toggle useless and making you crazy. Also, it's hard to tell when you buy them at the big box store if they're good or terrible. I try to avoid them too; I had to use them in my own block wall basement, as the block was too soft for any other type of expanding anchors.Back when I was working as a tech, I tried these without much success.

Multiple assemblies mounted on the fire wall:New one for me on this one. Installing a panel in a commercial office building, 277/480. Mounted it on a double sheetrock fire wall. The electrical inspector is requiring that I first mount plywood to the wall and mount my panel to that. I’m not finding anything NEC to back it up, maybe it’s a local thing. Is there anything in the NEC that calls those out??
Lag boltsCurious as to your mounting method. Toggle bolts?
I don't think it's code but majority of electric rooms now are putting up 3/4" plywood to support the panels and other cabinets.New one for me on this one.
