Is it possible to run 300 ft with 210 watts if I use 8 or 10 gauge wire and a higher voltage output (I saw one transformer with 22v option but it is for 900 watts, which is over double not sure if that matters)
Rachel: The formulas for calculating required wattage and line voltage drop are on pages 6-10 of the downloadable installation guide for the 300W multi-tap transformer. If you can't shorten your run length by using a second transformer you will need that 22V tap for 10/2 wire or a 18V tap for 8/2 wire in order to achieve 12V at the most distant fixture. Hope this helps. Bob Mason
