Is 15 amp circuit sufficient for 14.8 amp load?
Your 15A circuit will be fine, considering that both loads are noncontinuous loads and they are plugged into different receptacles (210.19(A)(1)/210.20(A).  The NEC treats the two receptacles in a duplex receptacle device as separate receptacles, by the way -- this means that you don't have to worry about the 12A limit on a single receptacle load on a 15A circuit (210.21(B)(2)).
