xkcd #2848: Breaker box
(imgs.xkcd.com)
A community for a webcomic of romance, sarcasm, math, and language.
While not foolproof, many power strips will have an integral breaker to trip if you exceed the power strip capacity. You could plug one of those into the outlet and the power strip would be a way to prevent an over-current condition. Of course, if you don't need to use it, there's no sense in rolling the dice on how reliable a power strip breaker is.
