What kind of switch do I need for a garbage disposal?
Replacement Switch for Garbage Disposal Purchase a replacement switch with the same amperage rating as the old one. Some garbage disposals run at 15 amps while others require a 20-amp circuit and switch. You should be able to find the switch you need in home centers and hardware stores in your area, if not online.
Where should a garbage disposal switch be installed?

Can a garbage disposal share an outlet?
Disposal and dishwasher can be operated on the same circuit; if their load is adjusted in a 20 amp or 15 amp circuit. It should not exceed 80%. There is a need for a dedicated circuit to deal with plug and cord connection mostly protected with AFCI protections but GFCI is also important in connections.
Should a garbage disposal be on a GFCI?
The National Electrical Code (NEC) does not require a garbage disposal to have GFCI protection. GFCI protection for this appliance is optional. Garbage disposals should be either hardwired or connected to an outlet through a grounded electrical outlet.
How do I wire a garbage disposal?
Wrap the bare-copper end of the green (ground) wire of the cord clockwise around the ground screw on the disposal (or use the ring connector). Tighten the ground screw with a screwdriver to secure the wire. Connect the white (neutral) cord wire to the white (neutral) wire on the disposal, using a wire connector.
What kind of wire do you use for a garbage disposal?
There are extension cords that are designed for garbage disposal. You will find these extension cords in different sizes, and depending on your circuit, you should buy a gauge wire for garbage disposal in the range of 14-20 NM.
Can you run dishwasher and garbage disposal on 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. It is very important to make sure that both the appliances do not exceed the amperage rating more than the circuit amperage or even close to it.
How does air switch for garbage disposal work?
A garbage disposal air switch is a type of pressure or plunger control knob that activates a garbage disposal by pushing a burst of air through a plastic or vinyl tube to a control unit mounted under a sink. These air switches do not rely upon electricity and thus permit mounting on counter or sink surfaces.
Does a garbage disposal need a 20 amp switch?
Seimens Q115 15-Amp Breaker This is the ideal size for most garbage disposals, although you could choose to use a 20-amp breaker. Make sure you check your box for compatibility before making a purchase.

Can a dishwasher and refrigerator be on the same circuit?
If you can meet the provisions in 210.52, and still end up under the load calculations in other parts of the code. AND the dishwasher is cord-and-plug connected, then it is possible to have the fridge and dishwasher on the same 20 ampere small appliance branch circuit.
Is there a difference between GFI and GFCI?
GFCI vs GFI. Ground fault circuit interrupters (GFCI) and ground fault interrupters (GFI) are the exact same device under slightly different names. Though GFCI is more commonly used than GFI, the terms are interchangeable.
How do you hook up a GFCI to a garbage disposal?
How to Wire a GFCI Outlet for a Garbage Disposal Install a metal electrical box under the sink within reach of the garbage disposal power cord. Run 12-gauge, 2-conductor cable to the box in metal conduit. Strip about 6 inches of sheathing from the end of the cable with a utility knife and separate the wires.
Does outlet under sink need to be GFCI?
The National Electrical Code, a minimum standard for electricians in the United States, allows for electrical outlets to be placed under the sink. However, all electrical outlets within a distance of 6 feet from the sink must have GFCI protection.
How many amps does a garbage disposal need?
Garbage disposal requires a circuit of 15 amps ideally. A 15 amp dedicated circuit is the best option for setting up one garbage disposal. Other than that, a garbage disposal can also work on a 20 amp circuit. Because in the kitchens of most houses, there is an electrical 20 amp GFCI outlet under the kitchen sink.
How many receptacles can be on a 20 amp circuit?
The answer to the question how many outlets on a 20 amp circuit is ten outlets. Always comply with the 80% circuit and breaker load rule, allowing a maximum load of 1.5 amps per receptacle. Remember that your circuit, wire sizes, and outlets must be compatible to avoid overheating and electrical hazards.
