It is not unusual for me to learn something from this BB. After reading all the comments I have revised my thinking to consider that the need is in the code for a branch circuit for a sign or outline lighting. The calculated load for this circuit is not less than 1200va. I do agree that if you have several small sign they could all be installed on the same circuit and they should not exceed 16a. by virtue of the fact that this would be considered a continuous load. I think there should be only sign outlets on this circuit. The load could exceed 1200va. if the load were 16a.- 1920va would be the calculated load for the service.
