Does garbage disposal require GFCI?
Technically, a garbage disposal does not need any GFCI protection but there’s a good chance that it already is if your home is relatively new. That’s because the law is currently written so that GFCI has to be installed for any outlets within six feet of the sink, which your garbage disposal likely is.
Does a garbage disposal need an electrical outlet?

A dedicated circuit is recommended, although your second-best option is to share it on a circuit with the dishwasher. Check your garbage disposal user’s manual for more detailed instructions.
Does NEC require dedicated circuit for garbage disposal?
A garbage disposal requires a dedicated 15-amp circuit, fed by a 14/2 NM cable with a ground. You may also elect to feed the disposer with a 20-amp circuit, using 12/2 NM wire with a ground. This is often done when the local code allows the disposal to share a circuit with the dishwasher.
Can garbage disposal be on shared circuit?
Can You Run a Dishwasher and Garbage Disposal on the Same Circuit? Yes, the dishwasher and garbage disposal can run on the same circuit. But they are more preferred to be powered by two different circuits rather than one.
Can a garbage disposal and dishwasher be on the same circuit?
Wiring a garbage disposal and dishwasher into the same circuit requires a 20-amp circuit breaker, like this one. You'll also need to make sure the total amperage of the two appliances combined does not exceed 80 percent of the circuit amperage rating.
Can a garbage disposal be on a 15-amp circuit?
Can You Use A 15-Amp Switch On A Garbage Disposal? Yes, a 15-amp switch is enough to handle 1/3, 1/2, and 3/4 horsepower disposal models. You can choose to upgrade these low-amp models to a 20-amp breaker if you prefer, but it is not typically necessary.

Can a Microwave and Garbage Disposal Be on the Same Circuit?
A microwave and garbage disposal cannot be on the same circuit and properly function. Both require a significant amount of power to run, and placing them on the same circuit may cause it to trip and the wiring to overheat, resulting in a fire hazard.
Can a Dishwasher and Garbage Disposal Be on the Same Circuit?
A dishwasher and garbage disposal can be on the same circuit if it’s allowed by local code and the total amperage doesn’t exceed 80% of the circuit rating. These two devices must also be on a 20 amp circuit instead of a 15 amp circuit.
Can a Refrigerator and Garbage Disposal Be on the Same Circuit?
A refrigerator and garbage disposal cannot be on the same circuit. According to the NEC, a refrigerator must be on its own dedicated 120-volt, 20-amp circuit shared by no other appliances.
Why Do My Lights Flicker When I Turn On the Garbage Disposal?
If your lights flicker when you turn on the garbage disposal, an overloaded circuit is the most common culprit. And if your disposal is on the same circuit as the flickering lights, then this is most likely the cause. Otherwise, it may be due to improper wiring or corroded or loose neutral wiring.
Final Thoughts
Garbage disposals should be on their own dedicated circuit for optimum safety and performance. Other appliances such as refrigerators, dishwashers, and microwaves should all be on their own dedicated circuits as well.
How many amps should a garbage disposal be on?
Ideally, a garbage disposal should be on its own 15-amp or 20- amp circuit. Second choice is to have it share a 20-amp circuit with the dishwasher. Putting the disposal on a circuit serving countertop receptacles is not an option.
Do you need a dedicated circuit for a refrigerator?
In the US, under the NEC, a residential kitchen fridge is not required to be on a dedicated circuit. A fridge can be on one of the minimum two required "small appliance branch circuits".
