tost 0 Report post Posted June 15, 2016 When I use my power drill (also borrowed from friend to make sure mine is not the cause) and run into tight spots, my RCCB and MCB (both the one with single push switch and the one with dual push switch) will trip, turning off all my electricity. So I bought a 10mA RCD plug http://www.horme.com.sg/product.aspx?id=2217 hoping no need to keep resetting the MCB. I also changed the RCCB but problem still there. But the tripping still happens. Is there any other thing I can do? Share this post Link to post Share on other sites
