In general, the nonmetallic cable used in a home consists of two or three wires, usually in a twisted pair. This type of cable is often referred to as "Romex," or similar brand names. Its sheath is made of plastic or paper, with the ground wire made of bare copper. Its use is limited to 15-amp circuits. Nonmetallic cable is typically used for general lighting circuits, receptacle circuits, and split-receptacle circuits.
The third reason is to always seek out testimonials. A trusted electrical company will have customers who can attest to their quality work. Ask to see examples of their recent work or check if there are any posted on their site or social media. Even though you cannot expect an impeccable installation, you should be able to expect the contractor's ability to quickly and efficiently fix any problems. Look at their reviews if you're unsure about a company.
