NMB WIRE 8-3 500' REEL – Product Description
🔌 What it is
A 500-foot reel of 8/3 NM-B (Romex) copper electrical cable used for residential and light commercial wiring.
🧾 What the shorthand means
-
NMB (NM-B) → Non-Metallic Building cable (Romex-style indoor cable with PVC jacket)
-
8-3 → wire configuration:
- 8 AWG copper conductors
- 3 insulated conductors + ground
- (black, red, white + bare copper ground)
-
500' REEL → 500-foot spool of cable
⚡ What it’s used for
8/3 NM-B is used for 240V circuits that require a neutral conductor, such as:
- Electric dryers
- Electric ranges / ovens
- Some HVAC equipment
- Subpanels (short runs, code dependent)
- Other 120/240V appliances needing both 120V and 240V capability
🔥 Electrical characteristics
- Typically used on 40–50 amp circuits (application/code dependent)
- Rated for indoor dry locations only
- Copper conductors with insulated PVC outer sheath
🧠 Simple explanation
This is a large spool of heavy-duty indoor electrical wire used for 240V appliances that also need a neutral wire (like dryers and stoves).
🔧 Key takeaway
- 8/3 = 2 hots + neutral + ground
- Used when appliances need both 240V and 120V components
- Comes on a long 500-foot roll for full-house or large job installs
