It controls the upstairs bathroom, some electrical plugs in the bathroom, and an outdoor light fixture with a motion sensor. It went off once over a year ago, and has kicked out three times in the last few weeks, twice within a half hour. There was no excessive load at the time it went off. The lights are out, no major current going through any of the outlets. In fact, it hasn’t ever gone out while the lights are on and my wife is using a hair dryer. The outdoor light fixture hasn’t been on either, since it usually occurs during the day, and that outdoor light is rarely on… it’s motion controlled, more for security than for lighting.
