            Is this good for 18kw genator

            1 Answer | 
            Answer This Question

            No, it will not. #1. Feeder or branch-circuit conductors generally must have an ampacity not less than the noncontinuous load plus 125 percent of the continuous load (NEC 215.2(A)(1) or 210.19(A)(1), respectively). For a 50 A load, that means an ampacity of at least (50 x 1.25 =) 62.5 A. Since NM-B cable ampacities are limited to no more than those of 60°C-rated conductors (NEC 334.80), 6 AWG copper NM-B has an ampacity of 55 A (NEC 310.16). #2. A 50 Amp receptacle requires four wires, including the ground (NEC 551.71(C) and Figure 551.46(C)(1)). The 6/2 NM-B contains only three wires, including the ground. #3. Type NM-B cable is an indoor, dry location only product (NEC 334.10(A)(1)). It is not permitted in wet or damp locations (NEC 334.12(B)(4)). You may use our Re3™ Building Wire Selector to help find the right wire/cable. The above recommendations are based on Southwire’s general interpretations of the latest codes and standards including NFPA 70® National Electrical Code® Edition 2023 and the applicable UL standards. It is the sole responsibility of a licensed electrician and the discretion of the local AHJ (Authority Having Jurisdiction) to approve all the wire and cable products and installation methods to be used for a specific application at different locations. There might be local regulations or unique environmental factors that might limit the use of a specific product. Additionally, the same type of product manufactured by different vendors might also have an impact on the applications. As a result, our answers to this request above are for reference only, and we strongly advise the end users to consult with a licensed electrician and the local AHJ before purchasing and installing any Southwire products.

              Worked perfect. Ran this wire to a sub panel with a 50Amp breaker supplying power in the main panel. Needed to run two separate 20Amp outlets for garage refrigerator and freezer. Also ran an additional 20amp line for a garage outlet where I can use my saws or charge all my power tool batteries.
