Most modern homes are equipped with tamper resistant or tamper proof outlets. ![]() AFCI can prevent fires that are usually caused by arc faults. A typical AFCI outlets contains a computer that continuously monitors the current and voltage and if there are arcs due to loose wires broken wires or wires coming in contact with each other due to improper insulation, the AFCI trips the solenoid and opens the circuit. ![]() The Arc-Fault Interrupt Controller or simply AFCI is another safety outlet. The following is a GFCI Outlet rated for 15A.Ī 20A GFCI Outlet looks something like this. Usually, the current difference of 5mA can be detected by a typical GFCI outlet. If the current in both the wires is not same, it means that there is a current leak to the ground and the GFCI outlet immediately trips. GFCI Outlets protects from ground faults by monitoring the current flow through the hot and neutral wires. The Ground-Fault Circuit Interrupter or simply GFCI is usually used in kitchens and bathrooms, where the area can be potentially wet and danger of electric shock is high. Large welding machines often use such outlets. The 50A 125/250V outlet is an industrial grade electrical outlet rarely found in residences. They are used with large appliances such as powerful driers. The 30A 125/250V Outlet is a heavy-duty receptacle that is suitable for both 125V and 250VAC supply at 60Hz. ![]() It is also used for powerful appliances such as air conditioners, air compressors, welding equipment etc. The 30A 250V outlet, as the name suggests, is used with 250VAC supply and can have a maximum current draw of 30A. It is often used for powerful appliances such as large ovens, electric stoves, etc. The 20A 250V outlet, as the name suggests, is used with 250VAC supply and can have a maximum current draw of 20A. Slightly powerful appliances such as microwave ovens often use 20A 120V outlet. Also, the 20A outlet uses a 12-gauge or 10-gauge wire with a 20A breaker. The receptacle looks slightly different from the 15A outlet with a small horizontal slot branching of a vertical slot. 20A 120V OutletĪnother commonly used electrical outlet in U.S. You can use these outlets for all small to medium powered devices such as smart phone and laptop chargers, desktop PC, etc. Internally, the 15A outlets consists of 14-gauge wire and are protected by a 15A breaker. As the name suggests, these outlets are suitable for 120VAC supply with a maximum current draw of 15A. One of the most common types of electrical outlets is the 15A 120V outlet. The following is a list of different types of electrical outlets. Let us now take a look at some of the commonly used electrical outlet types in our homes and offices. You insert the plug of the device or appliance into the electrical outlet and switch it on to power up the device. In order to use this electricity, it is then distributed all over the house either through in-wall or external conduits and reaches light bulb connectors and electrical outlets.Īn Electrical Outlet, also known as Electrical Receptacle, is the main source of electric power in your home. The electric power from your local utility is brought into your home through cables and is terminated at the distribution box with circuit breakers.
