Another approach to outlet wiring is to create pigtails. You create a pigtail by twisting together multiple wires of the same color (it's very important that they're the same color) and adding a short length of spare wire of that color. Twist clockwise using pliers, then screw a wire cap...
Although there's really no reason for it, homeowners often wire multiple GFCI outlets on the same circuit. This is overkill because a single GFCI will protect all the outlets wired after it in the circuit, but since the NEC requires GFCIs in so many places, DIY homeowners often overdo it....
Our object is to both to provide technically accurate and safe information and also to be sure that people who themselves are not experts and who may use the "wrong terms" such as "how to wire up electrical outlets in series" can in fact find a valid answer to their question. If you ...
He created one of the first practical electromagnets in 1824, which consisted of a horseshoe-shaped iron core wrapped with multiple turns of wire. Michael Faraday And then there’s the granddaddy of electromagnetism: Michael Faraday, a chemist and physicist who architected many of the theories ...
The GFCI outlets look very much like the regular outlets except for the two buttons in the center used to test and reset the outlet, as well as a pilot light showing its status (see Fig. 3). It should be noted, however, that used on any ungrounded installations, the GFCI receptacles ...
While ground fault circuit interrupter(GFCI) outletsmay be inconspicuous, these are common household items that could save lives. Before the advent of GFCIs, electric shock injuries were more likely to occur when someone was standing in water or otherwise in contact with water when using an elect...
Check too that the circuit breaker or fuse is intact and that no GFCI outlet controlling the branch circuit has tripped. Finally, test your outlets with a voltmeter or multimeter. They are relatively inexpensive. There are even apps that turn your iOS device (iPad, iPhone, iPod Touch) into ...
Next, look at the path the wire will take from your breaker box to the shed. You will need to dig a trench to run the conduit that contains the wire underground. The depth of that trench may depend on whether you use metal or PVC conduit and Ground-Fault Circuit Interrupters (GFCI)....

As you might imagine, it's a lot harder to kill someone with 120 volts than with 1 million volts (and most electrical deaths are prevented altogether today using GFCI outlets). To learn more, read How Power Grids Work. There's one major electrical concept left that we haven't discussed:...
