Hmmmmmm....just found this. Looks like other folks suffer the same issue I do. Wonder if 5 seconds is too long, though. Since the 1.5A was originally intended for the 60W Interphase, I guess 2.5 makes sense for 200, though these are so inexpensive it might make sense to start with the 1.5 version Heck, it resets itself so why should I worry about more cutouts vs. feweras long as they are reasonably rare as is the case now....
