Answer This Question
A: We would recommend the minimum gauge wire to be size 12 and 10 is preferred. Keep in mind 200' is about the maximum length run that a low voltage system can support. Voltage drop can be a real problem causing lights to be dim at the end of the run. You will also need at least 1 light of 20W within 20' of the transformer so the transformer can meet minimum load requirement.
