Condo-Commercial construction ?

[doug seibert]

Most Multi family residences will not allow sheathed electrical cable (or DIY)……you will need to pipe the electric to a full-sized 1 1/2″ fan rated box…..

You could use a wiremold product and leave it exposed or use an EMT conduit( and possibly flex) and metal box and leave it exposed or cover the ceiling with 3/4″ strapping and your ceiling tiles.

To anchor the box: I’ve always used “red heads” in concrete for loads that required good holding power.

“……measure Once…..cut Twice….
throw that one away and cut a new one….”
