Suspending Lights from EMT

[Mross506]

Situation:

A healthy debate started today in the shop regarding whether we are allowed to hand LED light fixtures from EMT using jack chain. (EMT is installed to code).

I've always been trained that it was not permissible to hang or support a device from EMT conduit but as I really read the code, I haven't found where it is that clear. I see where I can't attach other raceways or cable to it and I cannot allow it to be the only support for an enclosure or light but the pictures in the code refer to a device being attached to the end of the conduit rather than hanging from it.

I'm on the fence with it as it is a very easy way to install the lights and they are very light so I'm not worried about the conduit capacity. However, I was always brought up believing that was shoddy work...

You cannot hang the chain from a raceway. If the EMT is not being used as a raceway it can be used to support the fixtures via the chain.

Not permitted per 358.12(2).

Perfect! Thanks for calling out the reference! That is exactly what I was looking for!

It is possible to hang lights from Mae West that hold emt .

Can you clarify what you mean?

I've seen guys install another inverted Mae West from the screw of the existing one and drop a rod from there.

Take screw that clamps made west together, feed chain loop thru it and install the screw back. Now the light hangs from a Mae West and not from emt.

You would need to get permission from Mae first!

Oh 110.3 b install according to mfg recommendations.
It’s possible

I've gotta say I think 358.12(2) is one of those ridiculous, arbitrary, and dumb rules. Ok sure, hanging some heavy fixture off of 1/2" EMT right in the middle of straps that are 10 feet apart is probably not a stellar idea, but a blanket prohibition is ridiculous.

I agree. If you have a large rack of EMT's running down a hallway a 10 pound fixture hung off of the 4" EMT will never be a problem.

Remember guys, “it says what it says” as I’ve been reminded before.

as well we are not allowed to strap single cat6 cable to emt
