Hi, this is my first time posting. I'm feeling dejected and demoralized because my home repair project is going awry. I rented a floor sander for the weekend to work on my hardwood floors - never done this before, so it's all new. There's only one rental place in my small town so choices are limited. I rented an old orbital sander and brought it home, plugged it in, and it ran for about 30 seconds before blowing out the circuit breaker (marked at 20amps). Repeated this process about twenty times with different circuits until finally tried the one circuit marked at 30 amps. This time the sander didn't trip the circuit - but it ran for about thirty seconds then shut down on its own. Now I'm stuck in the middle of a project and I don't know what to do. I keep resetting it and restarting it - and it keeps shutting down. The rental place is closed until Monday. Does anyone have suggestions on ways that I can work out this problem on my own? Or are my floors not meant to be sanded this weekend?
