EXTENSION LEAD Meaning and
Definition
-
An extension lead, also known as an extension cord or power strip, is an electrical device used for extending the reach of an existing power supply. It is typically a flexible cable, constructed with multiple outlets or sockets, and a plug on one end for connecting to a power source. The extension lead allows users to connect multiple devices or equipment to a single power outlet, particularly when the original power source is located at a distant or inconvenient location.
Extension leads come in various lengths and configurations, allowing users to choose the most suitable option based on their requirements. They are commonly used in homes, offices, workshops, and other environments where there is a need for additional electrical outlets. The outlets on the extension lead enable the connection of various electrical devices simultaneously, such as computers, televisions, lamps, chargers, and other appliances.
Extension leads also provide enhanced safety features, including surge protection and overload protection, to ensure the safe and efficient operation of connected devices. The surge protection guards against sudden voltage spikes and helps prevent damage to sensitive electronic equipment. The overload protection helps to prevent fire hazards by cutting off the power supply if the connected devices draw excessive current.
In summary, an extension lead is a versatile and practical electrical accessory used for extending the reach of power supply, providing multiple outlets for connecting electrical devices, and enhancing safety through features like surge and overload protection.
