how many amps does a garbage disposal use

If you’re wondering how many amps does a garbage disposal use, the answer depends on its horsepower and motor load. Typical garbage disposal amps range from around 4 amps for smaller units to 15 amps for more powerful models.

In this guide, we have covered practical reference for every common HP rating and 25 popular models.

Garbage Disposal Amperage by Horsepower

Horsepower	Typical Running Amps	Minimum Circuit
1/3 HP	4-6 amps	15A
1/2 HP	4.5-6.5 amps	15A
3/4 HP	4.5-9.5 amps	15A or 20A
1 HP	7-15 amps	20A

These are running amps. Startup (inrush) current is 2-3x higher for a brief moment when the motor first engages. Your circuit breaker must handle this surge without tripping.

Amps vs. Watts

• Amps = how much current the motor draws (determines circuit/wiring requirements)
• Watts = total power consumption (Amps × Volts)

At 120V (standard household), a 10-amp disposal uses about 1,200 watts. But since disposals run only a few minutes per day, annual energy use is under 5 kWh — less than $1/year on your electric bill.

Amps matter for safety (circuit sizing). Watts matter for cost (energy bills). For disposals, the safety side is far more important.

Matching Your Disposal to Your Circuit

15-Amp Circuit (14 AWG Wire)

Supports disposals up to about 8 amps running draw — most 1/3 HP and 1/2 HP models. Safe for smaller households with lighter use.

20-Amp Circuit (12 AWG Wire)

Supports all disposal sizes including 1 HP models. Required for any disposal drawing more than 10 amps. This is the recommended setup for 3/4 HP and 1 HP units.

The 80% Rule

Circuit breakers should not carry more than 80% of their rated load continuously. An appliance on a 15A circuit should draw no more than 12A; on a 20A circuit, no more than 16A. Garbage disposals run intermittently (not continuously), so this rule applies less strictly — but inrush current must still stay within the breaker’s trip rating.

Conclusion

Most 1/3 and 1/2 HP disposals draw 4-6.5 amps and work on a 15A circuit. Most 3/4 and 1 HP disposals draw 7-15 amps and need a 20A circuit. Always check the nameplate before installation, and ensure your circuit and wiring match the disposal’s requirements.
