14/2 NM-B Wire With Ground 600 Volts

14/2 NM-B cable contains two 14 AWG copper conductors and a bare copper ground wire, with a rated voltage of 600V and is suitable for dry environments at 90°C. Compared with larger cables such as 12/2 or 10/2, 14/2 NM-B has a slightly lower current carrying capacity (usually 15 amps), but is more efficient and economical in light-load circuits.
In terms of specific applications, 14/2 cable is very suitable for indoor low-power circuits, such as ordinary lighting circuits, wall lamps, chandeliers, smoke detectors, and some low-power socket circuits in residential buildings. Due to its smaller size and greater flexibility, it is easier to thread, bend and fix during construction, especially suitable for wiring in small spaces. In addition, its cost is relatively low.

NM-B cable is UL certified. The cable has undergone authoritative and rigorous evaluation and testing in terms of design, material selection, manufacturing process and final performance. The cable must pass a number of key tests, such as insulation withstand voltage test, flame retardant performance test, temperature tolerance assessment, mechanical strength test, etc., to verify that it can withstand various electrical and physical stresses in actual use. These tests ensure that the cable will not cause safety hazards due to current overload, short circuit or mechanical wear during installation and use. UL certification is not only an important guarantee for the quality of wire products, but also a basic prerequisite for its legal sale and wide application in the North American market. For consumers and electrical contractors, certified cables provide reliable quality standards to ensure that the cables have excellent electrical performance, safety and durability in long-term operation.
