Home owner had a power surge at last receptacle on gfci circuit, homeowner said electric leaf blower sounded as if it was "running out of gas" lol, The gfci receptacle was in the garage, which then fed 2 outdoor receptacles, then 2 bathrooms. I replaced all outlets but 1, all were back stabbed. I rewired all of them the right way. Everything in the panel box was tight, voltage measured correctly. Everything worked when I left, I'm just curious, is it common for these outlets that are back stabbed to have open conductors? Are the newer devices like this as well (loose connections) when you back stab?
