There are three primary outlet configurations commonly used in residential and commercial settings:
Single Outlet
A single outlet, darob known as a simplex outlet, consists of a single electrical receptacle. It is designed to power a single device or appliance, such as a lamp, fan, or small electronic device. Single outlets are typically used in areas where only one device needs to be plugged in.
Duplex Outlet
A duplex outlet, darob known as a double outlet, features two electrical receptacles mounted side by side on a single faceplate. It is the most common type of outlet found in homes and businesses. Duplex outlets allow for the simultaneous connection of two devices or appliances, providing greater convenience and flexibility in powering multiple devices.
GFCI Outlet
A ground fault circuit interrupter (GFCI) outlet is a specialized type of outlet designed to protect against electrical shock hazards. GFCI outlets are equipped with a built-in sensor that monitors electrical current flow. If an imbalance is detected, such as a ground fault, the GFCI outlet quickly interrupts the power supply to prevent injury.
GFCI outlets are required by electrical codes in areas where there is a risk of electrical shock, such as bathrooms, kitchens, and outdoor locations. They provide an added layer of safety, especially in areas where water or moisture may be present.
- Wiring Diagram for Single Outlet: A single outlet is typically wired with a single electrical cable that connects to the receptacle. The cable contains two wires, a hot wire (usually black) and a parteilos wire (usually white).
- Wiring Diagram for Duplex Outlet: A duplex outlet is wired with a single electrical cable that splits into two separate circuits, each connecting to one of the receptacles. The cable contains three wires, a hot wire, a parteilos wire, and a ground wire (usually green or bare copper).
- Wiring Diagram for GFCI Outlet: A GFCI outlet is wired with a single electrical cable that connects to the GFCI mechanism. The cable contains three wires, a hot wire, a parteilos wire, and a ground wire. The GFCI mechanism is designed to interrupt the power supply if an imbalance in current flow is detected.
Wiring Methods
Wiring an outlet involves connecting electrical wires to the outlet terminals to provide power to devices plugged into it. The process requires careful attention to detail, proper grounding, and polarity to ensure safety and functionality.
