Our take on the Wirenco 6/3 NM-B, Non-Metallic, Sheathed Cable, Residential Indoor Wire, Used for Wiring Swiches, Outlets and Other Loads with Dry Applications (10 Foot Cut)

Wirenco 6/3 NM-B is non-metallic sheathed cable for dry, indoor residential branch circuits. It carries three 6 AWG conductors plus a 10 AWG bare copper ground, with color-coded PVC insulation under a nylon jacket and a 30 mil PVC sheath. The 600-volt rating and 55-amp allowable ampacity suit heavy loads like ranges, dryers and subpanels. It is equivalent to Romex NM-B and meets UL 83, UL 719 and ASTM specs, so it competes with Southwire and other NM-B brands on the same standards rather than on extras.
