With a patriotic origin, being "Made in America," this cable seamlessly marries technological innovation with top-notch craftsmanship. Its adaptability shines through as the NM-B cable finds its way into air voids within masonry block or tile walls, granted that these surfaces remain free from moisture-a testament to its versatility. NM-B cable is primarily used in residential wiring as branch. Engineered exclusively for above-ground installation within dry environments, the cable proudly carries a substantial voltage rating of 600 volts, ensuring robust performance. Southwire® Romex ® Brand SIMpull® NM-B (nonmetallic-sheathed) cable may be used for both exposed and concealed work in normally dry locations at temperatures not to exceed 90☌ (with ampacity limited to that for 60☌ conductors) as specified in the National Electrical Code. Widely embraced in residential building wiring, this cable plays a pivotal role as a dependable branch circuit, serving switches and outlets effectively. *Data provided on this page is subject to change based on different manufacturers' variances ** Images are for display purposes only refer to Product Technical Details for accurate information on the product.The Romex Type NM-B Copper Building Wire is thoughtfully designed to enhance installation convenience with its patented SIMpull Cable Jacket, facilitating smoother pulling, stripping, and overall setup. For worst case calculation purposes, we will assume 30 amps at 240 volts. Here we need to assume the voltage is 120/240 volts, with the greater load at 240 volts. 3 Stranded wire AWG sizes 4 Nomenclature and abbreviations in electrical. Use thhn individual conductors inside the conduit if you feel you need conduit. His friend was trying to tell him it will fit better in 3/4' when in fact it shouldnt be used inside conduit at all. Featuring a patented SIMpull Cable Jacket, this Romex Type NM-B Copper Building Wire is meticulously designed to simplify pulling, stripping, and installation processes. It wont fit inside a 1/2' conduit with any sort of bends or distance. Next, to the implied question, is 10 wire sufficient to carry 30 amps 75 feet. The argument probably stems from the issue of using the 10/3 romex. PVC jacket comes in yellow, orange, white, and black colors. So, kverrett, to start with, the maximum ampacity and overcurrent protection of 10-3 Romex is 30 amps. The cable has a polyvinyl chloride (PVC) insulation, making it perfect for harsh conditions. Non-Metallic Sheathed Cable, Thermoplastic-Sheathed Cable, 220 Wire. Romex is the brand name of a one type NM sheathed electrical cable made by Southwire Company, LLC of Carrollton, Georgia. The conductors are made of soft Stranded bare annealed copper. Simpull Jacket Designed For Easier Pulling. The cable has 3 conductors with a bare ground wire. Copper conductors are annealed (soft)copper. Also Known As:Ĥ-3 NM-B Wire, 4-3 NM-B Cable, 4-3 Non-Metallic Sheathed Cable, 4-3 Non-Metallic Sheathed Wire, 4 -3 Romex Wire, 4-3 W Grnd NM-B Romex, 4-3 Romex Type NB Copper Building Wire Standards: SOUTHWIRE 63948455 Romex Nm-B Non-Metallic Sheathed Cable with Ground, 10/3, 250 Ft Per Roll-2487710. Southwire Romex® Brand SIMpull® NM-B cable is manufactured as 2, 3, or 4 conductor cable, with a bare ground wire. The electrical wire is easily installed because it is specifically designed for easier pulling. The voltage rating of the cable is 600 volts. NM-B electrical wire can be used in air voids in tile walls. 3/4-inch Conduit: Up to 22 of the 14-gauge wires. 3/4-inch Conduit: Up to 16 of the 12-gauge wires. 1/2-inch Conduit: Up to 12 of the 14-gauge wires. The cable jacket is color-coded for quick size identification White - 14 AWG, Yellow - 12 AWG, Orange - 10 AWG, and Black - 8 AWG and 6 AWG. The National Electrical Code has specific regulations for how many conductor wires can fit within a conduit of each diameter size: 1/2-inch Conduit: Up to 9 of the 12-gauge wires. It can also be used for various building purposes, both inside and outside (the temperature should not exceed 90 ☌). Romex® Brand SIMpull® NM-B cable is designed for easier pulling, resulting in easier installation. Romex Type NM-B Copper Building Wire is commonly applied in residential building wiring as a branch circuit for switches and outlets. Designed specifically for submersible pump applications. 4/3 W/GRND NM-B Romex 600V Stranded BlackĪllowable Ampacity for 4-3 W/GRND NM-B Romex: 70 Amps Applications: 3 Wire with ground, 10 gauge, Twisted, Submersible Pump wire.
