![]() ![]() It will help a lot if you are aware of the kind of outlets in your house. 220-volt outlets are more prominent in other parts of the world. This layout of 120-volt outlets is standardized by the National Electrical Manufacturers Association (NEMA).ġ20-volt outlets are mostly used in Canada and America. The U-shaped round hole is for grounding. The 2 vertical holes are parallel and connected to the live and neutral wire. You need to plug the device in the 2 vertical holes and 1 round hole. Throughout North America, 15 and 20 amp 120-volt outlets are used. Appliances Powered by 120-Volt OutletĪs described earlier, all your everyday household appliances can be powered through 120-volt outlets. They are so common that if you don’t know that there are 2 types of outlets, you won’t know they are called 120-volt outlets. You see them all the time at your home and workplace. They provide a basic level of current for devices to work. These plugs have a higher rectangular prong for the neutral wire.ġ20-volt outlets are required for most of your appliances. Modern 120-volt outlets can also power the polarized plugs. Modern 120-volt outlets are primarily designed as duplex receptacles so that there are 2 places to plug in devices. The third hole is round, and it is connected to the ground wire. 1 of them is connected to the live wire and the other to the neutral wire. They are required for all the regular appliances at your home. These are the oldest types of outlets being used since the 1950s. You don’t need any specialized kind of wires to operate a 120-volt outlet. Therefore, these are the most common types of outlets in your home. On the other hand, your everyday devices such as vacuum cleaners and phone chargers can easily run on a 120-volt outlet. You should also put the wire and conductor with the right kind of strength to pull off 240-volts. They can’t run effectively on a 120-volt outlet. Some of the common devices that require a 240-volt outlet and plug are the washing machine, stove, and dryer. 240-Volt OutletsĢ40 volts is a higher degree of current for the appliances that need a higher level of pressure. Although you will mostly find 120-volt outlets everywhere in your house, some heavy equipment needs 240-volt Output and plug power to perform. The volts are the degree of current or pressure which the equipment needs to function correctly. You should know it before even moving your appliances. In this article of 120 Volt Outlet, you will know everything You Need To Know. If an interruption occurs in a switch, there will be no electricity beyond that point.Do you know your home has 240 and 120-volt outlets? If not, you must know the difference between the two before starting any electric work at your home. Voltage passes through these devices in order to continue down the line. Household circuits don't operate like that, you have a consistent average of 120 volt at each receptacle, no matter how many loads you have on the circuit.īy contrast, switches and circuit breakers are wired in series. And if the appliance in the first receptacle shorted out or failed in some other way, it would interrupt the current to the other outlets in the circuit. If wall receptacle circuits operated like that, you wouldn't be able to plug an appliance in down stream from another appliance in the same circuit because the voltage wouldn't be sufficient to run it. A series circuit will drop (use) some voltage at each load until it dwindles to an insufficient level at some point down the line. The load itself conducts current down the line to the subsequent loads in the circuit. In a series circuit, current must pass through a load at each device. But, in fact, all household receptacles are always wired in parallel, and never in series. It's common to describe household wall receptacles that are wired together using the device terminals as wired in series. ![]()
