A 15 amp circuit normally includes 14-gauge wires, while 20 amp circuits use 12-gauge or 10-gauge wires. Applications of 15 Amp & 20 Amp Outlets If the two circuits, respectively outlets with the different amperage do not seem too dissimilar so far, there is a clear, and most of the time regulated, distinction when it comes to their use.
What is the differnet between 15 amp and 20 amp?
The only apparent difference, of a 15-amp outlet and a 20-amp outlet is that the shorter-slot (for the plug’s narrower blade) has a squared, outward-facing notch in the middle, to accept 20-amp plugs, which cannot fit into a 15-amp outlet. The short answer is 5 amps. I don’t know how basic I need to get but think about water.
Can I use a 15 amp GFCI on a 20 amp circuit?

What is difference between 15 vs 20 amp receptacle?
A 20a receptacle will have one slot that is turned sideways or T shaped to allow a 20amp plug to be used. A 15amp receptacle on a 20 amp circuit will not overload the circuit. You will only be allowed to plug in 15a devices.
Should I get a 15 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!
Can a 20 amp GFCI replace a 15 amp GFCI?
According to National Electrical Code, only a 15-amp or 20-amp electrical receptacle can be installed to a 20-amp circuit. A 15-amp receptacle may also be installed on a 15-amp circuit. However, a 20-amp GFCI outlet may not be installed to a 15-amp circuit.
Will a 15 amp GFCI work on a 20 amp circuit?
The GFCI receptacle is rated 20 amps since it may have to interrupt a 20 amp circuit when it trips. As in the case of a kitchen appliance circuit. 15 amp receptacles can be used on 20 amp circuits without a problem.Dec 5, 2017
What happens if you use a 15 amp outlet on a 20 amp circuit?
You can overload a 15 amp receptacle if you use it to power an appliance that draws 20 amps or more. But a 20 amp plug cannot fit in a 15 amp outlet, to begin with. If you force a circuit to carry more current than its rating permits, the excess heat generated will melt the wires, starting a fire.
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.Oct 26, 2010
What is 20 amp circuit?
20-amp circuits are designed for a heavier load of electrical current than 15-amp circuit breakers. For commercial and industrial power distribution, the circuit breakers will have a higher amperage. [image source]
Is there a limit on the number of outlets on a general purpose circuit?
According to the NEC, although there is no limit on the number of lighting and/or receptacle outlets on dwelling general-purpose branch circuits, it does require a minimum number of circuits to be installed for general-purpose receptacles and lighting outlets [210.11 (A)].
Can an outlet be installed on a 20 amp circuit?
The amperage of the outlet must never exceed the amperage of the circuit. According to National Electrical Code, only a 15-amp or 20-amp electrical receptacle can be installed to a 20-amp circuit. A 15-amp receptacle may also be installed on a 15-amp circuit.
What is the difference between a 15 amp and a 20 amp GFCI?
What is the difference between 15 amp and 20 amp GFCI? The amperage of the outlet must never exceed the amperage of the circuit. According to National Electrical Code, only a 15-amp or 20-amp electrical receptacle can be installed to a 20-amp circuit. However, a 20-amp GFCI outlet may not be installed to a 15-amp circuit.
Can a 20 amp outlet be installed on a 15 amp circuit?
According to National Electrical Code, only a 15-amp or 20-amp electrical receptacle can be installed to a 20-amp circuit. However, a 20-amp GFCI outlet may not be installed to a 15-amp circuit. Click to see full answer.
Can a 15 amp GFCI be used in a 20 amp circuit?
A 15 amp GFCI receptacle may be supplied power from a 20 amp circuit. Other that gratuitously degrading the performance of the circuit if only one 15 amp receptacle is used in the circuit, there is no reason why it cannot be done. In fact, most receptacles come in pairs with a potential of up to 30 amps. What happens when you put ...
Can a 15A receptacle be used on a 20A circuit?
If the receptacle had the T-neutral, that would mean it could not be used on 15A circuits. NEC 210.24 allows you to put a 15A receptacle on a 20A circuit if it has 2 or more outlets on a circuit. One may also ask, what is the difference between 15a and 20a? 15a and 20a receptacles have different pin configurations.
Can I use a 20 amp receptacle on a 15 amp circuit?
What happens when you put a 20 amp receptacle on a 15 amp circuit? If your question is “can I connect a receptacle rated for 20 amps to a circuit designed for 15 amps?”, the answer is yes, because the receptacle can handle more current than the circuit is rated for.
Can a 20A receptacle plug into a 15A receptacle?
Any device that requires a 20A load will have a cord connecter with the 6-20R configuration. That means it won't be able to plug into any 15A device . The standard 15A receptacle is a NEMA 6-15R and the 20A receptacle is a NEMA 6-20R. Hope this helps.
Can I plug a 20 amp GFCI into a receptacle?
There are GFCI devices with that horizontal slot available, which will supply 20 amps to attached devices, and can be found online with a quick Google for "20 amp GFCI receptacle". You cannot plug a 20 amp device directly into any receptacle without that horizontal bar, be it a regular receptacle, or a GFCI. Share.
