JUMPER LEAD Meaning and
Definition
-
A jumper lead, also commonly known as jumper cables or booster cables, refers to a set of insulated, heavy-gauge wires with clamps on each end. This tool is primarily used to provide temporary electrical connections between two vehicles to jump-start a dead or discharged battery. The jumper lead serves as a bridge for power transfer from a functioning battery to the dead battery, allowing the recipient vehicle to start its engine.
Typically composed of stranded copper wire, the jumper leads come in various lengths and gauges to accommodate different vehicle sizes and battery capacities. The clamps, often color-coded, have teeth-like jaws that securely attach to the battery terminals, ensuring a firm and safe connection while transfering electrical current. The positive and negative clamps, which are typically red and black respectively, are carefully matched to the corresponding battery terminals.
When using jumper leads, it is essential to follow proper safety procedures. The jumper cables should be connected in the correct order, with the positive clamp attached to the positive terminal of the charged battery and the other positive clamp secured to the dead battery's positive terminal. Similarly, the negative clamp should be connected to the negative terminal of the charged battery and the last negative clamp to a metal, unpainted surface of the recipient vehicle's engine block. This sequence helps prevent sparking and potential damage to the vehicles' electrical systems.
The versatility and efficiency of jumper leads make them a valuable tool for roadside emergencies, providing a quick solution for starting a vehicle with a discharged battery without requiring external power sources.

Etymology of JUMPER LEAD
The term "jumper lead" is composed of two words: "jumper" and "lead".
The word "jumper" can be traced back to the 16th century, derived from the verb "jump", meaning "to spring off the ground". It originally referred to a loose outer garment worn by peasants or workmen in Britain. Over time, "jumper" came to be associated with a knitted or crocheted sleeveless sweater or pullover.
The word "lead" is derived from the Old English word "lædan", meaning "to guide or conduct". It initially referred to a rope or cord used for leading or fastening animals.
When these two words are combined, "jumper lead" refers to a pair of insulated electrical cables with connectors on each end used for temporarily connecting two electrical systems or components.
