Breaker ratings

[Willie Snyder]

Would I be able to load a breaker to 18A if the load was not continuous? And also are lighting circuits in commercial considered continuous load?

On a 100 amp breaker yes.
See definition of continuous load

I assume this is a 20 amp breaker you are referring to? The answer is yes, you can put up to 20 amps of non continuous load on a 20 amp breaker.

I agree an OCP can be loaded to 100% if the load is non-continuous. Commercial lighting without some sort of occupancy control is almost always a continuous load.
