I thought that was what the controller did. Youre saying there should be a fuse/breaker before and after the controller? 15A and 30/40A(depending on controller)?

I have never seen a commercial controller with the correct protection installed. That is one of the reasons they can't get UL certification. I've argued the point extensively with DXHydro, and his justification is a loophole in the code that is only meant for commercial/factory lighting under very tightly limited circumstances, none of which will ever apply to our situations.
I don't understand what you are asking in your last line - 15a ok but 20a not??
