THHN wire is the most common type of single conductor electrical wire used in the industry. You could possibly buy THHN, THWN, THW, THHW or THWN-2. Years ago each type was made for each specific installation, but nowadays the standard way to manufacture and purchase it is to buy the multi-rated THHN/THWN-2 version as a universal building wire.

NM-B and Romex® Cable
Romex NMB Electrical Cable



"NM" stands for Non Metallic which means it's manufactured with a PVC jacket instead of a metal clad jacket. Romex® is also NM-B cable manufactured and owned by Southwire similar to Kleenex® brand compared to generic store brand. NM-B electrical wire can only be used indoors because it doesn't have enough protection to be used outdoors even if it's in conduit.

Romex® and NM-B cable both have multiple THHN/THWN-2 wires with an overall PVC jacket. They're installed in homes and buildings running power from the electrical box to the lights, outlets and appliances.

MC Conduit Cable
Copper MC Cable



"MC" stands for Metal Clad because it uses an Aluminum Interlocked Armor as a jacket instead of the most popular PVC insulation. With a metal clad jacket Type MC electrical cables can be installed indoors without the use of conduit. The aluminum jacket was designed to act as it's on conduit to increase the installation time and save contractors and electricians money.

Copper MC cable can also be used outdoors and in conduit, not because of the jacket, but because it has a green insulated ground wire instead of a bare copper ground wire.

UFB Underground Cable
UFB Electrical Wire



"UF" stands for Underground Feeder because UFB electrical cable can be buried in the ground for life without the use of conduit or raceway. As you can see in the picture the jacket insulation covers each conductor individually for added protection. Remember, the second your Romex® NMB cable travels outdoors you need to upgrade to MC cable or UFB cable!! It will be slightly more expensive because of the added protection that is necessary for outdoor installations.
