So, I’m okay with the 15 amp receptacles and the 12/2 wire? You guys have me worried now.

A standard breaker protects the wire, not the outlets or the appliance plugged into them.

20 amp outlets are designed to be installed on a single "dedicated" 12/2 NMB 20 amp circuit. A large Window A/C unit for example will often draw close to the maximum current for a 20 amp circuit, and will therefore have a 20 amp plug attached to it, which "can not" be plugged into a 15 amp outlet. Items like this require a dedicated 20 amp circuit.

Yes, you will sometimes see multiple 20 amp outlets installed on a single 20 amp circuit, but this is a pointless exercise.
Yes, a 15 amp appliance can be plugged into a 20 amp outlet because it's safe to do so, but why waste the money.

The contacts for a 15 amp outlet can handle the same amount of current, but any appliance utilizing a 15 amp plug will normally draw less than 10-12 amps, which is not an issue for a 20 amp circuit. If too many items are running at once while plugged into multiple 15 amp outlets, the breaker will trip when or if the max current rating is exceeded. Again, the breaker is there to protect the wire.

Not sure, I’m not an electrician either. My buddy that is an electrician told me that was all I needed for my use. Lol. I hope he was giving me good advice.

They need to be 20amp receptacles and fed from GFCI breaker if in a garage. Looks like you ran 12-2 RX

15 amp recepticals are the cheapest and lots of folks just run the cheaper 14 gauge instead of 12 gauge wire. Most rec. never see a full 20 amps for long periods of time except for maybe commercial and industrial shops. For home shop use most folks are easy and the 15 amp rec. last for years. Use heavy drop cords and pull on them roughly, the cheap rec. break/bust easily.

He did run 12 wire, tough getting 12 wire on 15 amp receptacles some times. Depends on the braker he used.

You do not "need" to put 20A receps on 12G wire.

...but you DO "need" to put 12G wire on 20A receps.

I'm not a electrian but why 15 amp outlet instead of 20 amp.
@kiwigtx

I was taught, if you run 15 amps from the box, you run 14-2 with ground, from the box to the outlet with a 15 amp outlet, period. For a 20 amp, 12-2 with ground, one end to other with a 20 amp outlet. I'm not an electrician, but I've played one for 40 years. 20 Amp receptacles are more expensive than 15 Amp receptacles, which is why people some people will use 15 amp outlets on their 20 Amp circuit. But is it acceptable, , it is perfectly okay. The topic is controversial. Some experts say that the practice is dangerous. I follow my local code and the advice from a few friends that are electricians and one that has his own business. I don't mix and match different material. That just me.

If you put 15A receps on 12G wire, you have simply overbuilt the wire portion of the circuit.
You will not be able to plug in a 20A appliance, and the circuit will be fine.
This is also a potential upgrade path.

However, if you put a 20A recep on 14G wire, you can plug in a 20A appliance which could overload the circuit and cause a fire.

Make sense now?

You can’t put 15amp receptacles on a 20amp fed circuit. You certainly can put 15amp receptacles on 12 gauge wire but needs to be fed from a 15amp breaker.
