AC Power Cords
Connecting devices to outlets can only be done with AC power cords. These are cords with plugs on one end and holes that connect with devices on the other. They come in different lengths, to serve many purposes. You can use short power cables to connect two fairly nearby pieces of equipment together, or you can use a long power cable to bring power to a distant location for a device that couldn't easily be moved nearer to an outlet.
Whether you are using a power-hungry device, a low-power device, or one that requires power in-between, you will need an AC power cord that suits. It's not just that they can plug in at all: the right cord needs to go into the right socket. In terms of the basic power-to-device pathway, it's pretty standard how power cords work. Yet there is variety, most notably in the plug itself.
Choosing the correct power cord for your individual needs is crucial. Using the wrong type can cause anything from electricity not being supplied at all to your device not being able to access the amount of power it needs. To minimize the potential for these kinds of problems, consider having a handful of AC cables in stock at your house or in your office.

FAQs
Can extension cords be a reliable power source for other devices around the house?
Yes, extension cords can be a reliable power source for other devices around the house if they are used properly, ensuring they are rated for the appropriate amperage and not overloaded.
Which type of cord sets are appropriate for connecting a computer and monitor?
IEC C13 to C14 cord sets are appropriate for connecting a computer and monitor, providing a secure and standardized power connection.
AC Grounding Basics: Grounding Series (Part 4)
The NEC states that electrical systems be grounded to a point that the maximum voltage to ground underground conductors does not exceed 150 volts. It also states that any 3 phase 4 wire, Y configurations and Delta configurations have the neutral wire be grounded as well. These requirements cover any electrical systems, ranging from single phase 120 volts, all the way to three phase 480 volts AC.
Conductor Grounding
The conductor that needs to be grounded in these types of systems will always be the neutral wire. A bonding conductor is needed for use between the grounded conductor or neutral wire, and the equipment grounding conductor to the metallic enclosure of the main electrical service. It is important to make sure that a properly sized conductor is used to accommodate the potential surges that may occur in the electrical system.
When grounding in a separately derived AC system, which is a system where components such as a generator, can have the grounded conductor's continuity interrupted, possibly by a transfer switch, it is important to make sure that the grounding conductor is bonded to equipment grounding conductor of the metallic chassis on the load side of the electrical service through the use of a main bonding jumper. When continuity is not being interrupted on the load side, then it is critical to make sure that there is no bond between the neutral wire or grounding conductor and the metallic chassis of the electrical service. This will allow the main bonding to occur at the main service panel entrance point.
