14/3 WG ROMEX NMB

14/3 WG ROMEX NMB is a standard residential electrical cable specification.

🔌 What it means

• 14 → 14 AWG copper wire (smaller, lower amperage than 12 or 10 gauge)
• /3 → 3 insulated conductors + ground
  • typically black (hot), red (hot), white (neutral), bare copper (ground)
• WG → distributor/warehouse marking (not part of the electrical standard)
• ROMEX → trade name for NM cable
• NMB (NM-B) → Non-Metallic Building cable (PVC jacket for indoor use)

⚡ What it’s used for

14/3 NM-B Romex is typically used for 120V or multi-switch circuits, such as:

• Three-way or four-way light switch wiring (common use)
• Ceiling fan with separate light control
• Multi-location lighting circuits
• Split-controlled receptacles (less common, code-dependent)
• Small appliance control circuits (low load)

🔥 Electrical capacity

• 14 AWG copper = typically 15-amp circuits
• Used for standard household lighting and general-purpose outlets
• NOT for high-load appliances

🧠 Simple explanation

This is a standard household wire used mainly for lighting circuits and switch setups that need an extra traveler wire (red conductor)
