What Does Extension Cord Gauge Mean?
Before you select an extension cord, it helps to be clear about what gauge means and why it matters. Wires of inappropriate sizes are often inappropriate for the job, which can lead to problems in electrical circuits. The gauge of the cord refers to what is inside, not what is on the outside. By understanding how a gauge works, it becomes easier to choose a cord that won’t overheat or lose power with your device.
Understanding Extension Cord Gauge and Wire Size
The term ‘gauge’ with respect to extension cords refers to the thickness of the copper wire inside that cord. This is most commonly referred to as the American Wire Gauge (AWG). The electrical-receptacle system uses numbers to describe the size of the various wire components, and these numbers affect the load. When people review a gauge chart for extension cords, what they are really looking at is how thick the wire is and its current capacity. Thicker wires allow electricity to flow more easily, while thinner wires create resistance. People who incorrectly gauge may cause excess heat to be built up, a loss of precious energy, and damage other devices connected to it. In particular, the case of longer use affects the devices and products.
How Wire Thickness Affects Power Flow and Safety
The thickness of a wire affects the flow of electricity through an extension cord. Thicker wires will handle more electric current and are cooler. Using thinner wires to supply power to relatively larger tools or appliances will increase the heat. People often ask what gauge extension cord I need before plugging in their equipment for this reason. To prevent voltage drop, longer cords need thicker wires. A length extension cord wire size chart ensures that the cord circuitry is capable of handling the steady power flow from the outlet without putting undue stress on the wire.
Thicker Extension Cord Wires are Safer to Use
Using thicker extension cord wires will reduce the resistance of electricity and prevent heat from accumulating in the wire. An extended use of electrical cords accumulates immense heat, which is among the major reasons for electrical fires. It especially matters when indoor and outdoor devices adopt high power.
