Our take on the 8/3 Copper NM-B Non-Metallic Sheathed Cable, 1000 ft Reel

This is 8-gauge, 3-conductor NM-B sheathed cable with a bare ground, sold on a 1000 ft reel. It is rated for 40 amps at 600V and built for dry indoor branch circuits, including runs in air voids in tile walls. The 7-strand copper conductors and PVC insulation are made for easier pulling than solid 8-gauge wire. It suits electricians wiring ranges, subpanels and heavy 240V circuits, where it competes with 6/3 NM-B for higher-amp loads and with 8/2 for circuits that don't need a neutral.
