8/2 NM-B Electrical Wire, 125 ft vs Wirenco 8/2 NM-B Cable

Both are 8/2 NM-B copper cable with a 10 AWG ground, 600V rating and 40A allowable ampacity, so the electrical performance is the same. The real difference is length and packaging: the Sunco roll gives you 125 ft on a coil or reel for long branch runs, while the Wirenco is a 30 ft cut for short jobs. Owners of NM-B generally report it strips and pulls well when the jacket is warm and stapled properly; the Sunco's SuperSlick Elite jacket is the one feature that meaningfully eases long pulls. Buy by run length, not by brand.

• Choose the 125 ft Sunco roll if your run is long, you have multiple circuits to feed, or you want slack for routing around obstacles and future additions.
• Choose the 30 ft Wirenco cut if you are wiring one short circuit, patching an existing run, or want to avoid storing a large leftover coil.
