The most dangerous way is if the electricity finds a path to the ground through a human body. This can happen if you touch an ungrounded plug or outlet at the wrong moment -- the electricity can travel between the part of your body touching the outlet and your feet on the floor, causin...
GFCI can detect ground faults and stop power before more problems arise from straying current. Using a GFCI only makes it safer to use an ungrounded outlet. Therefore, a GFCI won’t offer a grounding pathway. Conclusion Grounding is a common process usually carried out in engineering. Having ...

Just as long as they realize they risk a shock hazard when using appliances that require a ground. It is their responsibility to live with the consequences. At the least, they should take the NEC's advice and label the outlet as "ungrounded" or (as a personal option and NOT specifically ...
Dealing with Ungrounded Circuitry Houses built before 1962 were not required to have grounded circuitry, and many still don't. If you live in such a house, there's no time like the present to start planning a panel upgrade and new wiring. If that's not in line with your or your landlo...

Any receptacle or device that's wired for GFCI protection on an ungrounded circuit should carry a visible label indicating "no equipment ground." These labels often come as little stickers included with new GFCI receptacles. If you install a GFCI to protect standard receptacles downstream of the ...
My MacMini 2011 has a two-wire-only power cable, and when you touch it, it "feels electrically ungrounded", especially if you are touching other items connected to it or nearby. How should I ground the MacMini? MacMini 2011 i5, 8GB, Radeon 6630M -OTHER, Mac OS X (10.7), iPhone4...
They do prevent ungrounded towers from "trickle charging" to high voltages. For amateur service on insulated towers or verticals, amplifier plate chokes work OK. 100 µH is adequate inductance for a 160-meter 1/4 wavelength vertical. Workshop entrance and ground: Entrance grounds are critical...
