Hey guys,

First time poster long time lurker.

I have tried a few different ways of hanging bundles of MC wire over the ceiling tiles, like 2" EMT 2 hole straps bundling 10 together. Or even running an EMT conduit the length with J hooks and strapping the bundles to it. I have a project coming up where I will need to run about 30 12/3 MC a total of 120 FT obviously not all going that length but every 5 ft each would fall back to their junction box.

I am just curious what others would do in this situation. How would you hang large bundles of MC wire above, keep in mind this will be going up before any framing so everything is wide open.

Thank you in advance
 
Please....

These rings are not to insure the woman's submission when she gets married!
They are named for their resemblance to part of a horse's bridle.

Threaded rod and couplings... but dropping 6' is going to allow a fair amount of swaying when pulling the first few MC cables.

You would be better off pulling the cables under the hooks and when all of them are run lifting them up.

We do this sort of thing but keep bundle sizes reasonable.

We would typically use 12 AWG steel ceiling tie wire. You can make a tool out of EMT to twist the top end to the steel overhead leaving the tie wire dangling. Run the cables and then lift them up and support with tie wire.

If no overhead steel you need ceiling guy tools, a pole Ramset for concrete or tool to put in the drill that puts hooks in wood from from the floor.

Like other guys are saying- use couplings and threaded rod. The rings come with 1/4- 20 threads on the stem, so 1/4'' rods suspended, and like someone said you pull the cable first and then lift it above the ring and set it into the ring afterwards. They also make wood screw points that have a 1/4'' threaded post on one end for wood ceilings. On those I just tighten the end of it into my cordless drill and use the drill to screw it in for me. They make a similar shot pin for ramset or hilti guns that has a 1/4'' threaded post on the end for shooting into concrete ceilings. It all goes in pretty fast and makes the job look much more pro than ceiling wire in my world, but who cares if you can't see it above the ceiling tiles.
 
Look in your Caddy book. Start with MCS101. Several different part numbers for mounting method. Maintains spacing to prevent derating.
