PVC COATED MC TYPE CABLE REQUIREMENTS

[TOXICSTUFF]

I have searched all over the code for this product. and I cant seem to find any articles relating to this type of cable. Basically in this building the GC is going to pour a 3" concrete topping on top of existing concrete. My question is can this PVC Coated MC cable be buried in this 3"topping? if so, where is it at in the code book?

Thank you

Based on Southwire's website it would appear it would be o.k. but I would definitely clear such use with the AHJ & Building (structural) inspector.

Thank you for your findings. I am aware that this cable is allowed to be used in concrete. My question is how deep must it be concealed in the concrete? would this be in working clearances? Were looking for an arcticle so we can present this to the AHJ.

There is no minimum cover distance when embedded in concrete in the NEC.

Although where concrete cover is required rather than optional there are depth numbers.
There may be structural or other reasons not to have the void too close to the concrete surface, but that is not an NEC concern.

any type MC-HL will work you might want to look at TC-ER as well but I dont know off the top of my head if it will meet code

Type TC (includes TC-ER) is not permitted to be "Installed outside a raceway or cable tray system, except as permitted in 336.10(4) and 336.10(7)".

336.10(4) is messenger-supported outdoors.

336.10(7) applies to industrial establishments (see section for details).
