Our take on the Cerro Wire 2/3 NM-B Wire with Ground

Cerro Wire 2/3 NM-B is two-conductor 2 AWG copper cable with a bare ground, jacketed in black for indoor branch circuits and feeders. It is heavy-gauge wire, so it suits high-amperage runs like subpanels, ranges and large appliances rather than lighting circuits. The only price on record is $18.16, listed since November 1, 2026, so there is no recent range to compare against yet.

Questions and answers

Is 2/3 NM-B the right wire for a subpanel?
Often yes for a 100-amp feeder, but the breaker and conductor size must match your panel and local code. Have an electrician confirm the ampacity for your run length.
Can this wire be used outdoors or underground?
No. NM-B is rated for dry indoor locations. Outdoors or underground you need UF cable or conductors in conduit.
What does 2/3 mean?
Two 2 AWG insulated conductors plus a bare ground. The ground is not counted in the jacket color or the "3".
How much current can 2 AWG copper carry?
Roughly 95 to 115 amps depending on termination temperature rating and code rules. The breaker must be sized to the wire and the load.
Is today's price a good one?
The only recorded price is $18.16, listed since November 1, 2026, so there is no history to judge it against. Compare the per-foot price with other 2/3 NM-B sellers before buying.
