I first posted a question on the lighting forum about whther my under cabinet lighting was a fire hazard, but forgive me, I thought I might get more answers on the kitchen forum. About a year and a half ago we had Kichler direct-wire low-voltage xenon under cabinet light fixtures installed during a kitchen remodel. One 1-light fixture kept burning out and the wiring housing would pop loose whenever we changed the bulb, and ultimately the fixture smoked itself. Kichler sent a replacement, but I couldn't get the wiring case to stay in place under the clips on the fixture mounting, partly because the electrician had crammed the ground wires into a space not available on the new fixture but mostly because there were so many wire nuts in such a little area. The internal transformer is a space hog. We didn't know anything about lighting so I made my choice on looks and that these fixtures had individual hi/lo switches and xenon bulbs. I got curious and tried pulling off the glass cover on a couple of the other fixtures, and surprise, the wiring part popped off along with the lens. I could see where the electrician had used a screw to push the wiring case into place under the clip in the base on one side and on the other side, where the wire nuts were, the case was too bulged out to stay in place under the clip. In spite of how hard it was to jam the wiring case into place, it would pop loose at a touch. Part of the reason was that the electrician had to substitute bigger wire nuts (I did too - couldn't used the small ones that came with our replacement fixture,) but I don't really see how all those wire nuts for the transformer and its wires and the supply wires and all the wire nuts can safely be crammed inside.

Question for the forum: has anyone else installed this type of Kichler fixture, and if so what did you do about it? Or was the electrician doing something wrong?
