What Size Breaker for Refrigerator?
A refrigerator requires a 15A breaker with 14 AWG wire on a 120V dedicated (recommended) circuit.
🔌 Wire Length & Voltage Drop Check
Refrigerator Wiring Guide — NEC Requirements
Refrigerators typically draw 3-6A running but may spike to 12-15A during compressor startup. A dedicated 15A or 20A circuit is recommended but not strictly required by NEC.
Pro Tip
💡 Use a dedicated circuit to prevent tripping when the compressor starts. Surge protector recommended.
Why a 15A Breaker?
The refrigerator draws approximately 6A at 120V (700W). A 15A breaker provides adequate protection.
Wire Sizing per NEC 310.16
For a 15A/120V circuit, 14 AWG copper is required per NEC Table 310.16 at 75°C. For runs over 75 feet, upsize to 12 AWG. Use our Wire Size Calculator and Voltage Drop Calculator.
Complete Parts List
To wire a refrigerator circuit: a 15A single-pole breaker, 14 AWG NM-B cable (Romex) for interior runs or THHN/THWN-2 in conduit for exposed runs, a NEMA 5-15 or 5-20 receptacle, cable clamps, and appropriate junction boxes.
