I have one in a metal box with a metal cover with the top marked "Ctl 600W MAX" and the bottom marked as unswitched. I used a 14# cord and use mine for specific applications. I doubt it would over dissipate if I plugged most TVs into it. It's harder to predict what the front end of a set would do because of variations between sets. I think most sets would survive with a shutdown. The lowered input average voltage might cause a switching element to have a higher duty cycle and average current causing a failure. I have seen a camera control unit power supply die that way. Specifics were a sine wave input of 77 VAC, rather than a phase controlled 120, but the net result was the same.

I would add that I think the guy should be shot for clashing a white duplex with an ivory or almond dimmer and cover like that!
