On transformers, what is meant by Primary and Secondary cords?
The Primary cord is the wire that plugs into the 110-volt outlet in the wall. The Secondary cord is the low voltage wire that runs from the transformer to the fixture or mounting block. Some of our transformers plug directly into the wall, with the transformer box hanging on the wall. (823.24.450 TCH pg. 8.57 for example) In this case there is no primary cord.
