Just so, can MC cable be used in residential?
Type MC Cable without an outside nonmetallic jacket can be installed in an “other space used for environmental air” in accordance with Section 300.22(C). These cables can be installed either indoors or outdoors and in exposed and concealed locations. They can be installed in a cable tray or in any raceway.
One may also ask, can armored cable be exposed? This casing needs to be attached to metal boxes. Another distinction is that some types of BX cable can be installed in exposed locations, either indoors or outdoors. NM cable and wiring must always be installed in an enclosed location (typically within a wall, ceiling, or under a floor).
Also know, can you put MC cable in conduit?
The individual conductors, in MC, are not approved for use in other raceways without being in the MC jacket. The fact it is allowed in any raceway means it is allowed in any raceway. When it is in a raceway it does not have to be secured to the box, it is secured to the raceway.
How do you connect an MC cable?
Install the connector into the box first You can attach a connector to MC cable, then join it to the box, but it's easier to mount the connector on the box before feeding the wires through.
Related Question AnswersWhat is the difference between MC and AC cable?
The biggest difference between the two cable systems is that MC has full size ground wire while AC uses a combination of the jacket and a thin bonding strip or wire to function as the equipment ground. Note: Early AC cable often does not have this bonding wire.What is the difference between MC and BX cable?
For those who are not familiar with the difference between the two, BX has a mechanical ground as part of the armored cable wall or jacket, where MC has an "extra" green wire that is used for grounding purposes.Is MC cable suitable for damp locations?
Type AC cable is approved by the NEC for use only in dry locations.

It is permitted in wet locations and underground where identified for such use. A conduit bender is the only specialized tool needed for working with EMT.How many conductors can be in a conduit?
Allowable Conduit Fill Capacities| Size and Type of Conduit | 14 AWG Wire | 12 AWG Wire |
