You have to check on the sheathing itself but mostly all household wiring is rated for 600 volts. I think you will find that NMS is rated at 300 volts.

No, the uninsulated conductor in nonmetallic-sheathed cable should only be used as the equipment grounding conductor. It should not be used for any other purpose to avoid creating a safety hazard.
For 14/2 NM cable, a 14 AWG equipment grounding conductor is used.
Yes, it is necessary to attach the bare equipment grounding conductor of a nonmetallic sheathed cable to the green hexagon-shaped grounding screw on a receptacle. This connection ensures that the grounding system is properly established, providing a safe path for fault currents and reducing the risk of electric shock. Proper grounding enhances the overall safety of the electrical system by preventing electrical hazards.
THHN is a heat resistant thermoplastic insulated conductor, usually a single conductor. Romex is a brand name for a nonmetallic sheathed cable, it has multiple conductors inside, the insulated ones are insulated with THHN insulation.
NEC, Article 336 covers the use, installation and construction specifications for nonmetallic-sheathed cable. Nonmetallic-sheathed cable may be used for either exposed or concealed wiring.
The wire conductor colors in a non metallic sheathed cable are black, red, white, and a bare copper.

Yes, nonmetallic sheathed cable is commonly permitted in residential wiring for power and lighting circuits in most areas. However, it is important to check with local building codes and regulations, as requirements can vary by location.
For 14/2 NM cable, a 14 AWG equipment grounding conductor is used.
Electrical Sheathing is various forms of metallic or non-metallic covering over conductors. Nonmetallic-Sheathed Cable is what is known by the brand name Romex.
The most commonly used wiring method for residential use is called nonmetallic sheathed cable. Other types of wiring methods are knob and tube, as well as service entrance cable.
