You should check your local codes but typically systems <30V are classed "Low Voltage" and don't have a code of their own. It's possible that in the future we'll see some additions to the NEC to cover LV but for now if you're adding an outlet (120V) to supply the transformer you'd need to get permits otherwise I'd recommend using a good UL listed transformer for the VAC to DC conversion and then be wary of your current load through the strings. Again, check local coding first.If you wire them in series to bypass the need for a transformer you'd DEFINITELY need to worry about code as you're running mains voltage at that point. Mains voltage that is exposed at every single one of those metallic button locations (cutting locations). Best to avoid that IMO.
