![]() However, the task of the non-specialist is simpler as you need to consider it in reserve. Though their existing items can withstand more power, this action is a precaution for harsh environments or the lack of ventilation. ![]() Hence, any decisions you make about wiring should develop based on a suitable temperature threshold to avoid melting or combustible.Ĭontractors often reduce the load when they install the cables behind the wall. Besides, overheating hides permanent hazards as friction produces extra heat when running through a cable. Scientists have shown that the capacity goes in line with temperature, as shown in the table below. Things To Consider When Choosing Gauge Extension Cord Temperature For this reason, adding 100 feet of wire to a device that stays 50 feet away is a bad idea. This physical principle is undeniable, as you can feel the heat generated along the line when the device works. The cable is also a resistor, thus creating friction and lowering the output. In simple terms, it means the loss of energy as it moves along a long wire. The root of the problems comes from voltage drop. One thing is certain: the longer the cable, the lower the processing power. Your choice will never be optimal if you ignore the extension cord length. Gauge Ampe (At 75˚C ) 6 AWG 65 amps 8 AWG 55 amps 10 AWG 35 amps 12 AWG 25 amps 14 AWG 20 amps 16 AWG 17 amps 18 AWG 14 amps 20 AWG 11 amps Voltage Drop Unfortunately, manufacturers often hide the gauge to amps for their extension cords from the public eye.īelow is a regular chart, but it’s not the whole story. Knowing the right rating for your electrical equipment is important because you should know if the cable can meet the needs of the equipment or not. Popular options today include 8, 10, 12, 14, and 16.Ī general rule of thumb is that the larger the wire (or the lower the AWG number), the better its handling capability. The term AWG ( American Wire Gauge) represents the thickness rating of the electrical cords. However, the meaning behind these tables also points to interesting facts. For instance, you might notice a 25 or 50-foot extension of a 16-gauge cord that can handle 1,430 watts and up to 13 amps. It is not difficult to understand the size charts.
