# What is the difference between a 15 amp and 20 amp GFCI?

**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.

Accordingly, is it OK to use a 20 amp outlet 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. If you exceed **15 amps**, the breaker will blow, and protect the **receptacle**.

Beside above, how many GFCI outlets can be on a circuit? You only need **1 GFCI** outlet per circuit (assuming it's at the beginning of the line and the rest of the outlets are loads). They are correctly wired in parallel - if they were in series, you wouldn't get the correct voltage at the other outlets when there is any type of load present.

Similarly, it is asked, what is the difference between a 15 amp and 20 amp outlet?

**20**-**amp** receptacles have a horizontal slot branching off one of the vertical slots. Electrical plugs designated as **20**-**amp** will not fit into **15**-**amp outlets**. A **15**-**amp** circuit is usually served by 14-gauge wire and is protected by a **15**-**amp** circuit breaker or fuse.

How many outlets can be on a 15 amp breaker?

for a 15 amp circuit this allowed for 10 outlets and on a **20** amp circuit 13 outlets were allowed.
