Kitchen appliances often contains heating elements and large motors that draw a lot of electrical current. Ranges, wall ovens, some garbage disposals, dishwashers and freezers require dedicated circuits.
Today's new dishwashers usually require a 20 amp circuit meaning they can plug into a 15 amp duplex receptacle or a 20 amp single receptacle. Today's code does call for GFCI protection too.
A dishwasher is normally put on a 20 amp circuit--all products sold in the us may come with 15 amp plugs but are rated for 20 amp circuits. Code only allows for 15 or 20 amp circuits. The only difference is how much the appliance can draw prior to tripping the breaker.
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.
If you wish to connect garbage disposal and a dishwasher to the same electrical line, you must use a circuit breaker with a capacity of at least 20 amps rather than one with only 15 amps.
An average home dishwasher will use around 10 amps. Amps usage will vary by brand and model. Knowing the answer will ensure you correctly set up your gadget to avoid short circuits or fire damage.
Requires a 120 volt individual, properly grounded branch circuit with a 3 prong grounding type receptacle, protected by a 15 or 20 amp circuit breaker or time-delay fuse.
Dedicated circuits are necessary to prevent dangerous overloads that could cause wiring to overheat and circuit to trip repeatedly, which could result in an electrical fire. The National Electrical Code calls for most major appliances to have dedicated circuits.
A dishwasher typically requires a dedicated electrical circuit with its own circuit breaker. This is because dishwashers use a significant amount of power and may overload a shared circuit. Additionally, many local building codes require dishwashers to have their own dedicated circuit for safety reasons.
Dishwasher Circuit
When installing a dishwasher, the circuit should be a dedicated 120/125-volt, 15-amp circuit. This 15-amp circuit is fed with a 14/2 NM wire with a ground.
Kitchen dishwashers installed in dwelling units require GFCI protection whether hard wired or cord and plug connected.
Dishwasher – A large range of dishwashers use the standard current of 110 volts. It is best to use an outlet that has a Ground Fault Interrupter or GFI. This will provide an extra precaution if the outlet gets wet. A GFI is designed to trip or disconnect power to prevent electrocution.
Dishwashers, disposals, and microwaves all tend to be power-hungry beasts, meaning that you're going to have a hard time fitting even two of the three on the same branch circuit, and putting all three together on a single circuit is a non-starter.
Many permanently installed appliances, such as kitchen vent hoods, dishwashers, and hot water heaters, also don't require junction boxes.
Unlike plug-in appliances, a dishwasher must be hardwired and hooked up to the home's plumbing. If you're for the challenge of installing it yourself, you can save a lot of money. Installing a dishwasher may seem daunting, but with the right instructions and a little care, it can be a rewarding DIY.
Typically, a master plumber is your best hire for installing your new dishwasher. Although licensed electricians and general handymen could complete this project, it is highly recommended that a master plumber does the job.
Most fridges will keep their amperage draw under 15 amps, so a 15-amp circuit isn't likely to trip even on start-up. But if the outlet feeding your fridge is on a circuit shared with other outlets, have at least a 20-amp circuit.
However, the dw is on a dedicated circuit, which means that if someone working on the appliance needs the power off, they can lock the breaker in the off position (there's a cheap plastic attachment that works with most breakers).
Electrical Requirements
You will need to run an electrical line to your Bosch dishwasher location from a dedicated circuit at the main breaker.
Answer: The receptacle must be located in the space adjacent to the space occupied by the dishwasher, not behind the dishwasher.
10 Amp Wire Size: Use a #16 AWG wire for appliances such as toasters, dishwashers, refrigerators, vacuum cleaners, or hair dryers. 30 Amp Wire Size: A #10 AWG wire is suited for a circuit powering an air conditioner or all appliances used in an RV.
The dishwasher is designed for an electrical supply of 120V, 60 Hz, AC, connected to a dishwasher-dedicated, properly grounded electrical circuit with a fuse or breaker rated for 15 amps.
A dishwasher installed permanent under the counter will use a 20 amp breaker with 12 gauge wire. The same dishwasher only portable on wheels will work fine using a standard wall plug outlet. (15 amp 14 gauge wire).
