Extension cords come in various lengths, from a few feet to 100 feet. Although copper wire is a very good conductor, it does have an amount of resistance that generates heat. This heat can potentially damage the extension cord as well as the devices and appliances that are connected to it.29 mar 2018
Is a shorter extension cord better?
You should use the shortest extension cord possible that will reach where the operator is trying to go. In most cases, the extension cord should never be the same length as the power cord. Extension cords have resistance. Longer wires mean more resistance and less power getting through to your equipment.15 oct 2020
Should an extension cord be long or short?
Longer extension cords can't handle as much current as shorter cords of the same gauge, so use the shortest possible cord to get the best electrical current. Choose cords with polarized or three-prong plugs. Thick, round, low-gauge extension cords are best for large appliances and tools.24 abr 2018
What is a good length for an extension cord?
Larger numbers mean smaller wires, which in turn means it can carry less power. A cord measuring 14 AWG is the thinnest we recommend—and at lengths of only 25 feet or shorter—and the much thicker 10 AWG is likely the thickest gauge you'll find in an extension cord.9 ago 2018
Is it safe to shorten an extension cord?
No. Replacing a cord on an appliance is safe, provided it's done in a reasonable way. Cutting off the existing cord at some point outside the appliance and tacking an extension cord onto that isn't a reasonable way. Even that could be done safely by someone who knows what they're doing with the right tools.
Does length of extension cord matter?
Extension cord length is an incredibly important factor. The longer the extension cord is, the more resistance. Extension cords come in various lengths, from a few feet to 100 feet. Although copper wire is a very good conductor, it does have an amount of resistance that generates heat.29 mar 2018
What sizes do extension cords come in?
Common household extension cords are available in 16 gauge (smallest), 14 gauge, 12 gauge, and 10 gauge (biggest). The lower the number, the bigger the gauge and the greater the amperage and wattage is.
