Thumbs down Are 20 Amp Outlets Required on a 20 Amp Circuit?

I know this sounds like a no-brainer, but I just became aware that there are different amp-rated outlets. I've just wired my basement and have all outlets on various 20-amp circuits. I presume I must use 20-amp outlets. Is this correct? I guess I've always worked with outlets on 15-amp circuits and bought the inexpensive standard outlets. From what I noticed the other day in Lowes, 20 amp outlets are considerably more expensive than the 15 amp ones. Thanks for helping a newbie!

General purpose outlets are permitted to be 15 or 20 amp interchangeably.

You didn't post your location. In Canada you need to match the receptacle to the breaker.That means on a 20 amp circuit you must use 20 amp receptacles. You can use the 20 T slots that permit both 15 and 20 plugs.

Sorry. My location is Ft. Collins, CO. From that first response, I take it that I can use 15 or 20 amp outlets on my 20 amp circuit. I would plan to use 20 amp outlets in my shop and exercize room where heavier equipment will be plugged in. Maybe also for the home entertainment system. Does that sound right? Thanks.

NEC 210.21(b) allows multiple (but not 1) 15A receptacles on a 20A circuit, and allows 15A receptacles to feed through to 20A devices.

We generally don't even bother mentioning 210.21(B) because most DIYers don't even know that such a thing as a simplex receptacle exists, and they would not usually install one.

Rodsnreels, if you put your city in the "Location" field of your profile, it will help you get more specific advice in the future.

The "heavier" equipment does not benefit from 20-amp receptacles, but it will benefit from $3 receptacles instead of 50-cent receptacles. A $3 15-amp receptacle is as good as a $3 20-amp receptacle.

just curious.....210.21

Does a simplex receptacle still "Qualify' as "General Purpose"?

No. The definition of "General Purpose" specifically requires two or more. But I suspect your question was rhetorical.

Thanks John for the advice on "better" outlets. I'll let you know how the basement finish goes. I'm planning for my inspections next week. Then on to insulation and sheet rock, etc.
