Safety standards require that outlets installed near water sources, like in bathrooms or kitchens, must be equipped with ground fault circuit interrupters (GFCI) to prevent electrical shock. 4 What is an emotional outlet, and why is it important? An emotional outlet is a way for individuals to...
Is the ground socket of a GFCI receptacle that isn’t connected to ground useful? (I'm in the United States, if it matters.) If the connected appliance had current on its ground pin, where would this current go in the ungrounded GFCI? If the current on the GFCI's hot and...
It all comes down to what a transformer actually is. In the simplest terms it is two coils of wire around an iron core. The incoming coil – called the primary – converts an electric field into a magnetic one. This magnetic field then induces an electric field on the second coil and ...
It can be caused byloose connections, miswiring, or worn insulation. During a ground fault, the flow of power increases dramatically, because it’s no longer restricted by wiring. A GFCI works by cutting power when it detects any such disruption in electrical current. ...
