Can a Fridge, Microwave, Garbage Disposal, Small Appliance, and Dishwasher be on the Same Circuit?

Many electronic appliances such as microwaves, fridges, garbage disposal, and more small appliances are to be powered with the circuit, so it lightens up countertops every day. If we check the traditional method, the wiring systems remain in the same circuit. However, when the Kitchen undergoes modern technology such as flooring, countertops, and more, you may require multiple circuits for taking the easy workflow.

What Type of Wiring does Modern Kitchens Demand?

In modern kitchen construction, you will need to fit multiple circuits to arrange everything seamlessly, such as plumbing wires or electrical appliances wires. Besides, it often includes adding GFCI and AFCI protection. GFCI has been required in the Kitchen for a long time, but AFCI is the latest addition in Kitchen. AFCI edition came in 2014 and extended in 2017 as the special electrical circuit to include in the Kitchen. This device is specially designed to sense the shock between fault connections. Further, AFCIs shut down the current flow before a fire can occur.

Besides, Kitchen should be safe, and you will need to check circuits since a silly mistake can cause greater damage. While checking kitchen appliances circuits, ensure that all connections include 15 amp and 20 amp circuits with AFCI protection. Here you should also note that both AFCI and GFCI are different in protection. Thus, you will need to fix those requirements about protecting Kitchen from shocks. 

You can install the kitchen protection as a combination of AFCI/GFCI. Adding the necessary protection is mandatory. Most appliances such as fridge, dishwasher, garbage disposal, microwave, lighting, and small appliances circuits require an AFCI circuit. The professional electrician can help you settle the kitchen circuits so you can work hassle-free and enjoy your kitchen décor.

Considering all the facts lets us know whether the appliances require the same circuit or different. Before that, let us understand the basics. 

What Does the Circuit Mean?

The electrical circuit contains a loop of wire that carries out energy from the beaker box when the service is plugged on. This wire loop safely handles the electrical load, less than the circuit’s capacity. However, if the circuit is overloaded for a long period of time, it may cause a fire. Thus, the safety device called circuit breaker disconnects the power when it is loaded to prevent shocks. 

What is Electric Capacity?

Electrical capacity is typically rated in amps of watts and current of demand. If the electric capacity increases by the increased demand of appliances used, it causes shock or may trip the electricity. Thus, modern households should be on a different circuit to avoid risk of the trip. Basically, modern households require 20 amps or 24, 00 watts on 120 volts; besides, big buildings require 30 watts or 30 amp circuits to work without a trip. Also, the quality of current falls upon the size of wire you are using. The bigger wire is, the safely it flows currently. 

Despite that, electric capacity depends on the demand for appliances. You should check the demand for appliances you need. Enlist the articles you need electricity and then check on the wire if your appliances require a high range of electricity such as dishwasher etc. You can add amps according to your house requirement. Appliances with motors may require a heavy amp to run the machine. To better understand the whole concept, let us see a few examples. 

Can a Fridge and Dishwasher Be on the Same Circuit?

Now in modern technology, electronic appliances have been developed that uses a dedicated 20-amp circuit. If you have a small fridge like the traditional era, then it may require less amp, but nowadays, most fridges need 20 amp. So, dedicated to 20 amp, which is 12/2 NM with wire with the ground, is required for wiring. 

However, the fridge does not require GFCI protection unless it is within the 6feet or located in the basement. But it requires AFCI protection. Thus, having a dedicated circuit to the fridge is mandatory. It is best to take into consideration the dishwasher too. In addition to this, the dishwasher alone requirement is 120-125 volt, depending on the brand you ate using. 

However, the expert recommends when installing a circuit, it should be dedicated. This would avoid the stress of electricity, and you can use both appliances without worry. 

Can a Microwave and Dishwasher be on the Same ciCcuit?

Whether you are using a microwave oven of the old model or advanced, the circuit should be defecated to 20 amp with 120-125 volt. Also, it requires NM wire from the ground to prevent shocks and other issues. Well, it is common to see most microwaves are plugged into the normal electrical circuit that can draw 1500 watts, which is much higher than needed circuits. 

Additionally, it does not require GFCI, but it needs AFCI, which is utmost required since the plug is almost plugged into the outlet. Thus, experts recommend one should unplug the microwave wire when not in use.

On the other hand, a dishwasher consumes 20 amp that is 120-125 volts. Thus, it is better to put off microwave and dishwasher on different ports just to avoid inconvenience. However, if you need a microwave for 30 seconds, it may not cause an issue, but it is best to use separate plugs if it is needed for a long time. 

Can Garbage Disposal and Dishwasher be on the Same Circuit?

Yes, since garbage disposal is part of the dishwasher. Thus, it can be run easily on the same circuit. All you need to do is ensure they do not run more than 80% of their capacity. However, from the beginning, it was not allowed by the operators, but with modern technology, it is allowed to be run on the same circuit. 

Garbage disposal is hardwired that used to shred out the dirt and food from the utensils and keep your dishwasher clean and fresh. The dishwasher operates on 15 amp with 120-125 volts. This wiring is often used to feed give 20 amp from the ground wiring of 14/2 NM.

Can Small Appliances and Dishwashers be on the Same Circuit?

Small appliances in the Kitchen are used to serve countertop and wall decors or kitchen racks lighting. Lighting is the basic requirement of the Kitchen, be it in the pantry, racks, cooking, and more. However, in the Kitchen, big appliances like fridges, microwaves, and dishwashers have their own circuits. Despite these, for kitchen decor, one circuit is enough, as it does not use much light during day or night. During night time most lights are used.  

Besides, one must know the following facts. 

  • A kitchen requires 20 amps of current for small appliances circuit. Thus for others, you need to have separate circuits.
  • The dishwasher circuit should be AFCI/GFCI protected to avoid any issue. Just to ensure everything works safe and you won’t have the stress of anything.
  • A dishwasher and garbage disposal can have the same circuit; however, others should be not. 

Thus, to sum up, things the answer is you can plug small appliances in the same circuit, but for others devices, your need an extra circuit. This not only eases your work but also keep your kitchen protective against the electric circuit. However, it is mandatory to have different circuits since Kitchen includes gas. If any damage occurs to electricity, you may need to pay hard for this. 

What are the Things to Keep in Mind When Choosing a Circuit Breaker for Kitchen?

You will find various options in the market that may satisfy your choices at first glance. But you should be extra careful when buying a circuit as your whole Kitchen’s life depends on it. Here, we have discussed some of the important aspects that you need to keep in mind. 

  1. Check voltage rating- Must buy a high-quality breaker that meets the high voltage capacity. 
  2. Find Frequency- Make sure the breaker can save frequencies up to 600 amps. 
  3. MIC (maximum interrupting capacity) – Determine the MIC to ensure the chances of system failure.
  4. Current Rating- Ensure the current rating that runs in amps.

The Bottom Line

We hope with the above information you got to know that every kitchen appliance is it microwave, fridge, the dishwasher should be on different circuits instead same. This would prevent the risks ad give your Kitchen a smooth workflow. Besides, to complete the circuit work, one must check with an electricity expert to avoid complications.
