do you guys run your own ceiling grid wire for using bat wings or do you use the wire for the ceiling grid. im talking about erico caddy part # kx if batwing isn't the name used everywhere. and if you do run your own wire do you terminate the bottom end to anything? code requires us not to use the wire being used for the ceiling grid. thanks

We shoot our own #12 wires for lighting and raceways.
Attach to the fixture support wires or 1/4 electrical all thread whrer available.
Use 1 size larger for all thread clipping.

The yellow thing is what we call a banana clip.
Well actually a plastic version that I don't see much.
The metal ones are thinner, less interference with the tile.
Also the B-line have a bit of play and preferred compared to the Caddy.
That way you stay solid but don't lift the grid.
The county wants the electrical attached on clips.
Their idea is if the ceiling is pulled down by firefighters the electrical support wires un-clip and stay hanging.

For a suspended hard lids which is very common here, they don't care if we use the ceiling support wires. 300.11 states for ceiling grids, not suspended framed drywall ceilings. For those when we shoot and tie a wire I like to get the guys an angle clip to tie onto and screw into the framing.
