I’d give this transformer zero stars if I could. It works, however was VERY difficult to install. You think; two terminals in, two terminals out, no big deal. Well, whoever designed this was passive aggressive in the first degree and a downright masochist. It has MINIATURE screws with shallow slots to hold supply wires in place, a couple more tiny screws for a wire clamp and more screws for the cover and after you get them all in place, then one wire pops loose. Of course you’re installing it under a cupboard, and working upside down. The output side has pressure clamps that would still be a challenge if you had three hands. Whoever designed this transformer should go to transformer hell and have to do nothing but install this transformer for eternity!
