Rep Power: 12
yes hart i am serious, i have a power strip with internal breaker removed. just for testing breakers, it works well. I have used it up to a 40 amp breaker before. if its a two pole break just test each phase separately. also you need to remember that our power is different than yours. yes it gets warm under a larger load, but its not like your walking away for hours.
now a short trip test is a little riskier and certainly much brighter. actually i will replace a breaker before i short test it on purpose.
sometimes you need to rule out other problems that just changing the breaker wont show you. i have seen some crazy things, like 1 15 amp circuit trying to power a 20 amp load ( a big window ac unit ) that would run fine as long as it did not cycle more than every 5 mins and the tv was off.
