Low voltage loops in landscape lighting

[pacscott]

What is the code on use of low voltage loops when using dual coil transformers? One manufacturer says 300 watts maximum on runs and you can not loop from one xfmr circuit to the next (a single xfmr with dual 300w coils wired in the same can) another manfacturer says no problem and your load capability will increase to 600w when you loop the two together (parallel wiring) as well as better balance the lighting levels of all the fixtures on the loop? Who is right?

For the application the code would referr to the manufacturer, see NEC section 110.3(B).
But it would appear to me that wiring the transfomers in parallel would add capacity, however I don't have all the details...perhaps someone else will have experience.
