The number of amps that a GFCI switch can handle depends on the type of GFCI you are working with. Most GFCIs are either 20-amp or 15-amp, and can handle up to that specified amount.
Should I use a 15 amp or 20 amp GFCI? Kitchens and bathrooms should always have 20 amp gfci outlets. However, you must be using number 12 wire for 20 amp gfci or regular outlets If your wiring is number 14 guage then use a 15 amp. So, the wire size and breaker size together should be rated for 20 amps!
How do I know if I need a 15 or 20 amp GFCI outlet? Tip: The easiest way to determine whether a circuit is 15 or 20 amps is to look at the corresponding breaker or fuse in the breaker panel. Dedicated circuits are electrical lines that carry an electrical current to one single outlet.
Should I use 15 or 20 amp outlets? Considerations. Almost all household appliances, lamps and power tools have 15-amp plugs, and almost all household receptacles have a 15-amp rating. If you need to change a receptacle from one rated at 15 amps to 20 amps and you are not comfortable working with electricity, you should hire a licensed electrician.
Can 15 amp outlets be used on 20 amp circuit? You cannot push a 15 Amp plug into a 20 amp receptacle. 20Amp plugs are typically assigned to devices like air compressors and saws that require a lot of power. For the most part, you don’t have to worry about overloading your 15 Amp outlet by plugging a 20 Amp device into it.

What does a 20 amp plug look like?
A 20 amp receptacle will have one slot that looks like a sideways T. If it is a dedicated circuit it would be a single receptacle instead of a duplex. If you look at the breakers in your breaker panel and there is a “20” on the handle, it’s a 20 amp circuit.
Should I use a 20 amp GFCI on a 20 amp circuit?
The wires (electrical conductors) between the 20 amp rated circuit breaker and this GFCI outlet receptacle (or any outlet receptacle) must be at least 20 amp rated (gauge 12). It doesn’t matter if the end device is 15 or 20 amps rated.
What is the difference between a 15 amp and 20 amp switch?
Most residential switches are rated at 15 amps, whereas industrial and residential switches usually are rated at 20 amps. Additionally, industrial and residential switches are made with sturdier components. Dimmers: A dimmer is a kind of switch that can raise and lower the brightness of a light.
Should a freezer be plugged into a GFCI outlet?
However, GFCI’s are prone to a phenomenon called “phantom tripping,” meaning that they sometimes activate -shutting power off to the circuit – under normal, everyday voltage fluctuations. So freezers and refrigerators should never be plugged into GFCI’s.
Can a fridge and washing machine be on the same circuit?
Refrigerators are considered noncontinuous duty loads. Loads that draw current for less than three hours at a time are allowed to be on the same circuit with other noncontinuous loads, as long as the total load does not exceed the circuit breaker rating.
Can a dishwasher be on a 15 amp circuit?
A dishwasher should be on at least a 15 amp circuit. 15 amps is enough for most dishwashers on their own dedicated circuit. A dedicated circuit is a plug used for just one appliance, with nothing else plugged into it. Some dishwashers draw more power than most, and may need to be placed on a 20-circuit breaker.
How many outlets can I put on a 20amp 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.
What wire is used for GFCI outlets?
GFCI receptacles are used in areas near a water supply, such as bathrooms, kitchens and basements. These outlets use standard ROMEX® wire in 10, 12 or 14-gauge.
What color is 20amp wire?
Yellow 12-gauge cable is typically used for 20-amp circuits that power general household outlets used for a variety of plug-in appliances.
How many GFCI do you need in a kitchen?
You only need one GFCI if it’s installed as the first outlet in the circuit and wired properly. Every outlet in the kitchen was required to be protected by GFCI.
How many amps does a dishwasher pull?
Household dishwashers use 10 amps of power, mostly. Having said that, your breaker should be on a higher rating than the appliance being used for safety purposes.
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.
Can I run a refrigerator on a 15 amp circuit?
You should have refrigerators and freezers installed on a 15-20 amp dedicated 120 volt circuit. This will avoid an electrical overload due to your current wiring not being capable of handling the additional power.
What is a 20 amp outlet used for?
The 20 amp outlets are designated for big consumption appliances and power tools, like air compressors, so it is not unusual to find them in almost every kitchen and sometimes even in garages.
What happens if you use a 15 amp switch on a 20 amp circuit?
15A switch will burn without 20A fuse ever noticing it. They must break first to protect the rest. If they don’t, they are no more a protection. If you want to use 15A switch you have to protect it with at most 15A rated fuse/breaker.
Do I need 15A or 20A switch?

Can a 14 2 carry 20 amps?
I would say 14 gauge wire anywhere on a 20 amp circuit is not OK. The purpose of the breaker is to cut off power before the wiring overheats. If you plug in several devices on an outlet that total 20 amps, you will exceed the safe working capacity of the 14 gauge wire without tripping the breaker.
Should a garage refrigerator be on a GFCI?
