This is 50 feet of 6-gauge, three-conductor copper NM-B cable with a bare ground, sold in a coil. It is the standard feeder and large-load wire for ranges, dryers, subpanels and EV chargers in residential wiring. The SIMpull jacket is the main selling point: it pulls through conduit and studs with less friction and strips cleanly, which is why electricians favor it over generic NM-B. It is stiff 6-gauge copper, so it needs wide bends and strong hands; for 6-gauge branch work it is the usual pick against store-brand Romex.
