Okay but say I bring an MC cable into a wire way or is that not allowed?
MC Cable, Conductors in conduit markings ect..
- Thread starter Therealcrt
- Start date
Which type?
Raceway Surface Metal,
A metal raceway that is intended to be mounted to the surface of a structure , with the associated, couplings, connectors, BOXES, and fittings for the installation of electrical conductors.
I would say a box can be considered a raceway.

Ok.
Seems misleading per the definition which includes the word "boxes".
Point is, seems if the conductors aren't marked I agree with the OP they would not be allowed to extend from the box down to the panel.

Here are my thoughts on what is going on(not what is strict code, nor information about what the CMP or UL decided).
1) Conductors pulled in conduit could reasonably have different requirements than conductors contained in cables or used in boxes. The key point is _pulled_. A conductor pulled into a conduit has to survive the friction of being dragged the full length of the conduit. Think about the thin clear sheath over THHN conductors that isn't present on the conductors in NM cable.
2) A conductor not suitable for pulling in conduit might be perfectly suitable for use in a box.
3) When a cable is attached to a box, the cable is available right there at the box, so any markings on the cable are available for inspection (at least at the time of installation). When the outer sheath of the cable is stripped away, if the markings are removed you no longer have the necessary identification available.
4) Only _some_ of the conductors used in MC assemblies are actually identified as suitable to be pulled in conduit. The conductors in NM cable assemblies are rarely (if ever) identified as suitable to be pulled in conduit.
5) Despite what I said in 1) about it being _plausible_ that conductors for pulling in conduit might have different requirements, it seems likely any modern circuit conductor with modern insulation is perfectly suitable for use in conduit.

Brother go back and reread the exact reply you sent on the definition… talks about the raceway itself and then it says associated with couplings connectors boxes you can’t just take the definition out of context you’re one of those guys huh?
The use of the wording “with associated couplings connectors and boxes” made it seem as though it was referring to the complete assembly as a raceway.
