What is a Fifteen Amp Twenty Amp Feed-Through?

A "Fifteen Amp Twenty Amp Feed-Through" typically refers to an electrical outlet or device designed to support two different amperage ratings. These outlets are often used in residential or commercial wiring to accommodate circuits that may have varying amperage needs. The 15-amp side is compatible with standard appliances and electronics, while the 20-amp side supports devices that require higher power, such as certain tools or heavy-duty appliances. Feed-through means that power can pass through the outlet to additional outlets downstream, allowing multiple devices to share the circuit. It is essential to ensure proper installation to prevent overloading or electrical hazards.
