Does a combo receptacle/USB outlet meet the intent of the required receptacles in 210.52? There is only a single outlet so I am not sure whether it does or not.

Saw one yesterday that, looked like a GFCI, but where the buttons would be were the USB ports. Made by Cooper.

There is no requirement that we install duplex receptacles. You could install single receptacles throughout the entire dwelling if you wanted to.

I believe the concern is that the devise has a 15 amp rating, so could it be placed on a circuit with a 20 amp overcurrent devise? Good question.

That's a very good point. The one I saw was a duplex so you don't have that concern.

I brought this question up a month ago at a meeting with about 6 or 7 cmp members. Jeff Fecteau from UL answered the question and said Yes it does meet the req. of 210.52 for small appliance branch circuit . He also said that it could not be fed with a 20 amp individual circuit unless it was a 20 amp unit-- which they make

Question: Since I imagine most 15 Amp single receptacles would have terminals rated for 20A, like a duplex, what is the safety issue, code aside?

Are you guys assuming the OP was asking if the USB receptical on the combo counts as the 2nd receptical "needed" to satisfy code when putting a 15 amp device on a dedicated 20 amp circuit?......You all either hijacked the op's thread or deciphered the question way better than I did
....or maybe 210.52 is way different in the 2011 than in the 2008. In the 2008 it covers alot of ground.(no, not grounding)

I'm pretty sure he was asking if this one, rated at 15A, could be put on a 20A circuit.

Ahh, so it's not a question of whether or not the 15 amp rated 120v standard receptacle half is OK, it's a question of whether or not the 15 amp rated USB receptacle half is allowed on a 20 amp circuit.

It is allowed on a 20 amp circuit but not if there the single recep. is an individual circuit.
The question, in my mind is whether or not the usb constitutes another outlet that does not serve the counter. Remember all kitchen counter receptacles cannot be connected to other outlets unless they serve the ones specified for small appliance branch circuit. The usb does not serve the small appliance branch circuit so is it compliant?

I agree if that is what he was looking for but I assumed we all knew that.
