Before connecting the trash disposal to an electrical outlet, you must determine how many amps it consumes. In other words, it will trip if you don't use a circuit with enough amps to handle the required amperage rate while the trash disposal is running. 

This blog post will explain why knowing how many amps trash disposal draws is crucial. As a bonus, we'll provide you with tips on selecting the ideal garbage disposal for your particular circumstance.

How many amps does a garbage disposal use?

Garbage disposals consume between 2.8 and 7 amps and 500 and 1650 watts when operating. It may require 12 to 18 amps and 1500 to 4500 watts for a limited period at startup. These figures may differ depending on the features and size of the trash disposal.

Garbage disposals powered by a 12-horsepower engine typically draw 4 to 6 amps on average. In order to determine how much power the disposal can handle, the amp rating must be taken into account.

The amp-rated garbage disposal is required for residences with large families and a lot of food waste to dispose of. If you live alone and don't generate a lot of trash, you might be fine with less powerful garbage disposal.

Is it necessary to have an electric garbage disposal?

Trash disposal requires either a grounded electrical outlet or a hardwired connection to a power source. This contains a separate waste disposal circuit. This is a basic power requirement for most trash disposals. There are, however, numerous trash disposal types and brands to pick from. As a result, before installing a new garbage disposal, read the manufacturer's instructions in the user manual that came with the garbage disposal.

What is the electricity consumption of garbage disposal

What is the electricity consumption of garbage disposal?

The horsepower of your trash disposal influences how many watts it will require. Garbage disposals are available in a variety of horsepower capacities. The most common horsepower numbers for trash disposal are 1/2, 1/4, and 3/4. Trash disposal powered by a half-horsepower motor consumes around 373 watts.

A quarter horsepower draws 186 Watts, while a third horsepower draws 559 Watts. Examine the body of your trash disposal to ascertain its horsepower. If you're still having problems, consult the user guide. Knowing the horsepower number of trash disposal, you can now calculate how many watts it consumes.

How Much Money Do Garbage Men Make? Hourly Wage
Despite the obvious disadvantages of trash collection (such as unpleasant odors and heavy physical work), One may identify various advantages of this work. If you pick a career in trash collection, you can expect better job stability and access to benefits than many other jobs. Even though this is…

Waste disposal of 3/8 HP.

The average power usage for a 3/4 HP trash disposal is 5.5 amps and 605 watts, even though it draws up to 15 amps and 1800 watts for a brief moment at the start.

A 1/2 HP trash disposal uses four amps and 412 watts on average. It can draw up to 13.5 amps and 1680 watts from the battery for a short time.

The 1/3 Hp type is the smallest and most energy-efficient trash disposal available, consuming only 2.8 amps and 305 watts under normal operating settings. Depending on the unit's efficiency, these data may double or even soar to six times their typical value during the unit's first starting. During startup, expect to see approximately 11.25 amps and 1500 watts of power consumption.

One horsepower is required for commercial or heavy-duty trash disposal (HP). When turned on, it consumes approximately seven amps and 840 watts. It can draw up to 21 amps and 2145 watts when turned on.

Where can I obtain a garbage disposal breaker?

You'll need to know the breaker size for the new trash disposal installation. Trash disposals, which use about 15 amps, typically require a 20-amp breaker. Depending on the model, a 30-amp breaker may be required.

To be safe, stick to the instructions supplied by the product's manufacturer. The dishwasher and garbage disposal share a 20-Amp Circuit.

If the garbage disposal is installed, the garbage disposal and dishwasher can share a 20 amp circuit. While a dedicated circuit for the garbage disposal and dishwasher is preferable, sharing a single 20-amp circuit with these two appliances is not bad.

You should connect the trash disposal to an existing established 20 amp circuit in your kitchen if you want to save time and work. You should only run one appliance simultaneously to prevent overloading the shared circuit. Because doing so will draw a significant amount of amps when combined. As a result, there may be a tripped circuit. As a result, if you wish to use both devices simultaneously, sharing a single circuit with two appliances may not be the ideal solution.

Is it required to have a trash disposal circuit breaker?

Yes, the trash disposal does require a circuit breaker. There are several advantages to using a separate circuit breaker for trash disposal. If your garbage disposal has a motor, you may not want it to cease running because it consumes a lot of electricity.

Starting a motor from a standstill or turning it on may require nearly double or even six times the energy. When a motor is turned on for the first time, it consumes a significant amount of electricity, which may cause a circuit breaker to trip due to a lack of load capacity.


Disposal systems normally utilize between 75 and one horsepower to do their job. Seven hundred twenty watts is the equivalent of 0.60 amperes on a 120-volt circuit.

One should only run garbage disposals for 15 minutes to avoid tripping the circuit breaker. If many appliances are on the same circuit, One should start the dishwasher or washing machine first.

Cleaning the trash disposal with soap and water regularly is the best way to avoid unpleasant smells. Use ice cubes and lemon peels to get rid of stuck-on food particles.
