What is AC Power Plug?
AC Power Plug is a portable electric connector that consists of at least two metal contact spikes designed to make contact with the corresponding points connected to the power supply, usually contained in the protected electrical outlet. With the exception of real metal contacts, the AC power plug is protected by an insulated grip that is designed for easy insertion into a socket or extraction. The power supply is transmitted from the plug to the device using an insulated cable. They all have at least two spikes - one called "alive" or "hot", and the other tip, usually called "neutral" or "cold". Many of them have a third tip that only performs a current in case of insulation failure. These tips fit into the electric outlet slots and make contact with metal elements inside the output, which are connected to the corresponding parts of the electrical system.
i in zEMI Electric plugs differ depending on the size of the load designed for transmission. The "Standard" AC POWER plug in the United States is designed for home stream, which is up to 15 amps at 125 volts. It consists of two parallel metal blades, each 0.625 inches (1.6 cm) long and 0.25 inches (6.35 mm) wide and may include the third tip: a rigid metal pin the same length as the blade that fits into the corresponding opening in the electric output. Since the 1950s, many alternating current outlets with polarized slots have been produced, while the neutral slot is wider than the hot slot. This configuration ensures that the polarized alternating current plug with a wider neutral blade can only be inserted into the output in the correct way and ensure the replacement flow of electricity inside the device.
electrical outlets for higher loads, usually 220 - 240 volts, have a different number and alignment slots and alternating plugs for these devices such as electric dryer and stovesMore and heavier spikes and oriented to match the outlets. Overall in the United States there are eight different types of power plugs
One of the main disadvantages of the US plug-andlet system is that the design allows the spikes to attack-the current-front before the plug completely inserts into the output and the face of the handle comes into contact with the facial output plate. It is therefore possible for a person to touch the metal spikes of the plugs while performing electricity, and get shock in the process. It is also possible for a partially insired plug under tension, with exposed tips bearing a current, which represents a significant risk of fire.
Electric selections in North America and in some parts of South America will adapt to standard American AC plugs, called type A plugs and type B. Some type B connectors are made for 20-Amp perimeter and have an angle of neutralThe blade.
worldwide is used by a dozen different types of plugs with corresponding electric sockets. In each of them it contains AC AC plug. In many cases, safety features are incorporated into the design; For example, many outlets are embedded so that the grip of the plug fits into a niche before the tips are made with the power source and are under voltage, eliminating any possibility to come into contact with any part of the plugs while performing the current.
Given the multiple designs of the AC Worldwide power plugs, and the fact that the AC power plug is only suitable for specially designed to be travelers to learn about the outlets and get adapters for these devices such as computers and shaving machines.
