When calculating circuit load, what should I add for outlets?
In a residential load calculation, general-use receptacles are included in with the 3 volt-ampere (VA) per square foot general lighting value.  

In other than dwelling units, receptacles are calculated at 180 VA.

If you wanted to use the 180 VA value, it would be 1.5 amperes (180VA / 120V = 1.5 A).
