Series circuits are somewhat rare in house wiring, but they are sometimes used in strings of Christmas lights or landscape luminaries, where one light bulb failing will cause the entire string to go dark. When the bulb goes out in a string of holiday lights, it creates an open circuit in the wiring. However, many modern holiday light strings now connect via a parallel circuit so that a string can remain functional even when one of the bulbs is defective.
Most newer LED holiday lights are wired as parallel circuits. Much more common than series circuits are those wired in parallel—including most household branch circuits powering light fixtures, outlets, and appliances. A parallel circuit is also a closed circuit where the current divides into two or more paths before coming back together to complete the full circuit.
Here, the wiring is configured so that each device is in constant contact with the main circuit pathway. Individual devices merely "tap into" the main circuit loop, much the way freeway ramps allows cars to exist and enter a freeway without interrupting the main highway. Most standard volt household circuits in your home are or should be parallel circuits. Outlets, switches, and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit.
Sometimes this continuous pathway is created by "pigtailing" into the circuit wires in order to power an outlet or light fixture the pigtails are the exit and entrance ramps for the current flow. Two-wire cable is run between the gfci's, and the hot and neutral wires from the source are spliced to the line terminals at each device. The load terminals are not used and each device provides its own, single-location protection. Here a gfci receptacle is added at the end of a row of duplex receptacles for single-location protection.
The first outlet is connected to the source and 2-wire cable runs from box to box. All wires are spliced with a pigtail at the devices to pass current to the next. The load terminals on the gfci are not used and it does not protect the other receptacles in the circuit. Here one ground fault circuit interrupter protects multiple duplex receptacles coming after it, known as multiple-location protection. Two-wire cable runs from the gfci to all the following outlets. The line terminals on the gfci are connected to the circuit source and the load terminals are connected to each following outlet with a pigtail splice.
This keeps each duplex receptacle connected directly to the gfci. By code there is a limit to the number of conductors allowed inside an electrical box depending on the wire gauge you're using and the size of the box. While wires are conductors, they aren't the only ones in an electrical box. Devices like switches and receptacles are also considered conductors, and they add to the total present in the box. All metal parts that qualify as conductors must be added, to determine the total you will have in the final installation.
Find a detailed explanation of how to count conductors here. It's common to describe household wall receptacles that are wired together using the device terminals as wired in series. But, in fact, all household receptacles are always wired in parallel, and never in series. In a series circuit, current must pass through a load at each device. Written by Connor Doe.

Wiring in parallel gives greater reliability to the devices on the electrical circuit, but larger electrical boxes and more wiring connections are required. In this article series we illustrate basic connections seen in the field for the black, white neutral or grounded conductor), and ground wire when hooking up an electrical receptacle (wall plug or "outlet"). Watch out: mis-wired electrical receptacles are d. Procedure for Wiring an Outlet. A standard electrical outlet has two brass terminal screws, two chrome ones and a single ground terminal, which is green. When you wire a single outlet to a live circuit cable, you connect the black wire to one of the brass screws – usually the top one, but it doesn't matter – and the white wire to one of the chrome screws. Again, it doesn't matter which chrome screw you choose, but the convention is to choose the one opposite the brass screw to which you attach the black wire. If you wanted to ignore code and wire your outlets in series, the procedure would be the same. Connect the black wires to the brass terminals on the outlet you're wiring, connect the ground wires to the ground terminal, then twist the white wires together and cap them. Switched Outlet Wiring and Tab Removal Procedure. This electrical picture series shows the vital procedure that must be performed in order for the switched outlet to work. If this procedure is not done then the most typical problem will be that both upper and lower outlet will be hot instead of one being controlled by the wall switch. When this procedure is done correctly it will produce a switched outlet also known as a Half Hot Plug. This procedure shows how the outlets have the tab removed from the "hot" side or Brass side of the outlet which allows the top half of the plug to be. 244 245 246 247 248
