  • Current Transformers - A Quick Look

    I thought you might like to see this. I was snooping around the internet last week and bumped into a box of these 15A current transformers for a little over a buck apiece on the closeout rack. I bought about 25 of them plus a few 20A and two 100A models. They have load resistors installed...
