Wire size, breaker size, and circuit requirements for common household appliances. Based on NEC standards. Always consult a licensed electrician for actual installations.
10 AWG copper wire on a 30A, 240V double-pole circuit. Electric dryers draw 22–24A and require a dedicated circuit with 4-wire connection (NEC 250.140).
6 AWG copper wire on a 50A, 240V double-pole circuit for most modern full-size electric ranges. Some compact or older ranges specify 40A (8 AWG copper). Always check the nameplate.
6 AWG copper wire on a 50A, 240V GFCI double-pole circuit. NEC Article 680 requires GFCI protection and a disconnect 5–50 feet from the spa, within line of sight.
Depends on charger amperage. A 48A charger (most common) needs a 60A circuit: 6 AWG copper THHN with 75°C terminations, or 4 AWG NM-B. A 32A charger needs a 40A circuit with 8 AWG copper. EV chargers are continuous loads — the circuit must be rated at 125% of the charger current.
