WG ROMEX NMB 6/2

WG ROMEX NMB 6/2 is a standard heavy-duty electrical cable specification.

🔌 What it means

• WG → distributor/warehouse labeling (not part of the official electrical standard)
• ROMEX → trade name for nonmetallic-sheathed cable
• NMB (NM-B) → indoor non-metallic building cable (PVC jacketed)
• 6/2 → wire configuration:
  • 6 AWG copper conductors
  • 2 insulated wires + ground
  • (typically black, white, plus bare copper ground)

⚡ What it’s used for

6/2 NM-B Romex is used for high-power 240V circuits that do NOT require a neutral, such as:

• Electric water heaters (larger units)
• Electric ranges/ovens (some configurations)
• HVAC condensers (larger systems)
• Electric dryers (some setups depending on wiring requirements)
• Subpanels or feeder runs (short distances, code dependent)

🔥 Electrical capacity (typical use case)

• Commonly paired with a 50–60 amp breaker (application-dependent)
• Designed for 240V high-load circuits
• Copper conductors with heavy insulation for residential use
