How Many Amps Does a Garbage Disposal Use?

Garbage Disposal amperage at 120 V and 240 V

Same 550 W load: the current halves when the voltage doubles. Garbage Disposal is typically a 120 V appliance in US homes.

The startup surge lasts a fraction of a second; it matters for generator sizing and breaker trip curves, not for your electric bill.

Breaker and circuit for a garbage disposal

At 4.6 A, a garbage disposal fits comfortably on a standard 15 A or 20 A household circuit (kitchen countertop receptacles are on 20 A small-appliance circuits per NEC 210.11(C)). For a dedicated circuit, guidance is a 15 A breaker with 14 AWG copper (75°C terminations).

Guidance only: actual circuit sizing depends on your unit's nameplate, wire run length, and local code. Confirm with a licensed electrician. See the wire & breaker size chart for the full NEC ampacity table.

Measure what a garbage disposal actually draws

The figures above are typical ratings, and this load is usually hardwired or on a 240 V circuit, so a plug-in meter can't reach it. A clamp meter reads the current on one conductor at the disconnect or panel without breaking the circuit; opening a panel is work for someone qualified, and the voltage pen confirms a circuit is dead first.
