Couldn't a chase nipple be considered a "thread able raceway" that's been pre-threaded by the factory?

Not in my opinion. Threadable means that you can thread it after it's been manufactured like RMC or IMC. You can't thread a chase nipple.

Sure you can, you just won't be removing much (if any) metal. Running a die over threads that have already been cut is (ironically) called "chasing threads". It's typically done to clean-up damaged or poorly-formed threads.

Pedantic? Perhaps. But with all due respect, by your logic, then a close nipple would also be considered "non-threadable" as it's also fully pre-threaded by the manufacturer.

I guess the question is: at what point in the manufacturing process must the threading occur for the item to be considered "threadable"? Only at the job site? Anytime after it leaves the distributor? Anytime after it leaves the manufacturer?.......

OK, by using that logic then I can thread an EMT connector too. Does that make it a threadable raceway?

I don't know about that but I do know a chase nipple is a conduit fitting per UL and that makes it acceptable in a service. No different then an LB.

I would agree with that more than calling it a raceway. So as a fitting does it require a bonding bushing, locknut or wedge, etc.?

Let's see...

1. Is it metallic? Check!
2. Does it fall into the classification of EMT, IMC, or RMC raceway? Check!
3. Is it threadable? Check! (Just because the manufacturer cut the threads and not you, does not negate the fact that it's can be/was threaded.)

So I would say, yes, an EMT connector is a threadable raceway!

Going back to your original list, tell me where it directly and specifically list EMT fittings, conduit bodies, etc? I think it's understood that "EMT", as a class, includes all EMT associated L&L connectors, etc.
