Cleeds,
This may help you understand why it is safe and does meet NEC.

Cheater plug safety
jea481mPerhaps you should read the code that you referenced: " A single receptacle must have an ampere rating of not less than the overcurrent device protecting the branch circuit." You cannot use 15A devices on a 20A circuit and be compliant with NEC. |
Perhaps you should read the code that you referenced: Cleeds, Please go back and reread my post. I said two or more 15 amp receptacles can be installed on a 20 amp branch circuit. A duplex is two receptacles. Trust me it does meet NEC code. It is done all the time in commercial office buildings. Jim |
jea48 Trust me it does meet NEC code The NEC is updated every three years and the source you previously cited is 14 years old. Sorry, but using a 15A device on a 20A circuit is not compliant with current code. I don't doubt, however, that "it is done all the time." Perhaps you'll trust Bob Vila more than me. If so, read this. |
I think I see the issue. :) Nominally 15A receptacles can do 20A... I know it’s weird. :) The issue is the socket vs. the current capacity. The straight pin sockets are not designed to accept 20A plugs, but ARE designed to be connected to a 20A circuit. That is, a circuit with a 20A breaker and 12 ga. wire. Weird, right? :) This is designed in because using a 20A circuit is super convenient. You can use it to feed a pair or more 15A sockets so that for instance, you can power up to 2 x 10A devices without tripping. Best, Erik |
