Power outlets come in different designs and types. The National Electrical Manufacturers Association (NEMA) groups these systems into four standard categories according to amperage and voltage that they are designed to hold.
NEMA 5-15 R: it requires 120V and a 15-amp grounded receptacle . it is used to carry current for normal household devices such as lamps and other small devices.
NEMA5-20R: it is similar to the 5-15R only that it requires 20-amp grounded receptacle. Usually, it carries current for large household appliances such as fridges, microwaves and cookers.
NEMA 6-15R: it is characterized by 220-240V and a 15-amp grounded receptacle. It has a standard high current appliances such as space heaters, air conditioners and compressors.
NEMA 6-20R: It is similar to NEMA 6-15R in all respects only that it is used to power heavy tools in workshops plus the above devices.
Home Wiring and Outlets
Standard home wiring are appropriate for 120-volts when used together with 15 ampere-20 ampere circuits. Most people are connected to power that has 15 amps for powering the lamps and other small gadgets. Remember that large appliances are now plugged into power outlets that feature 20 amperes.
Other Specialty Outlets
Other specialty power outlets are used to reduce the number of extra cords needed to complete the connections. They also help to reduce the number of cords designed to be linked with a specified type of appliance.
They include the following:
Rotating outlets: The outlet openings for this type of outlet rotate in order to accommodate many plugs from several power sockets such as charger.
20-amp outlets: They come with a single vertical slot connected with a horizontal slot. It usually serves high-current appliances that use 20-amp circuits.
Surge suppression electrical outlet: they feature built-in protection to give protection against any surges. They do so without the need to install external surge protection devices.
