Either shell out a few bucks to buy one& slap it into a power strip... or scavenge a similar/lower rated one from some scrapworthy device. Idea is- the 5er or lower will pop WAY before risking anyone else getting shut down. I had a "test box" with Variac. volt& meters and switch selectable breakers from 1/2 to 15 amps for test/hacking and it saved a lot of headaches let alone preventing damages:>
