They should put a disclaimer on them, they are NOT designed to continuously monitor anything over 1400 watts or so. This thing caught fire after 3 days of continuous monitoring of 1475 watts. Although the maximum value is 1875 VA, this is not monitored for long. If you plug something close to 1800 watts it will most likely melt the block or fuse. What this can do is check how much current you are using for baseline and then turn it off.
