Dos and Don’ts of Extension Cords
With so several extension wire choices, it can be exhausting to create the proper selection. Do you associate with the "one size fits all" approach or purchase a wire specific to every application? The following three tips will facilitate you decide on the proper extension wire for any state of affairs. Initial, consider the atmosphere you're operating in. The outer layer of the wire (jacket) protects the wires from moisture, direct sunlight, cold etc. The jacket incorporates a designation that's created from a sequence of letters, and every letter encompasses a that means.
(image: https://upload.wikimedia.org/wikipedia/en/1/14/Counterfeit_extension_cord_06256.jpg)An extension cord for lawn mower plug might have 2 or 3 prongs. The third prong suggests that that the twine is "grounded," providing a further path for electrical currents and contributing to overall safety. The ground pin (third prong) is an important safety feature of heavier duty extension cords and ought to never be removed or bypassed in any method. Grounded (3-pronged) extension cords should be used with larger appliances.
Wire gauge is that the thickness or diameter of an extension cord’s internal wire. This thickness is measured by an American Wire Gauge (AWG) number: the smaller the amount (000 to forty), the thicker the wire. For most home and outdoor use, search for a gauge rating between ten and 18 AWG. You'll sometimes notice a wire’s AWG variety (additionally called a gauge rating) on the twine’s outer jacket—that’s the layer of thermoplastic that surrounds and protects the electrical wires (see Jacket Strength, below). The gauge rating is usually paired with the number of conducting wires inside the twine. As an example, a 16/three twine suggests that 16-gauge wire with 3 wires within.
To increase safety and stop accidental shocks, some extension cords now feature inexpensive, engineered-in GFCI (Ground Fault Circuit Interrupter) receptacles - simply like people who ought to be installed in your kitchen and bathtub. A GFCI immediately cuts off all power when it detects any current imbalance on the line.
Extension cords and surge protectors are not the identical things. The purpose of a surge protector is to divert or block excess power by grounding it. Even minor surges could injury sensitive electronics, thus plugging them into surge protectors (or extension cords with designed-in surge protection) is very important.
If the facility demand on a device is listed in watts, divide the wattage by a hundred and ten to convert the rating to amps. If the twine you’re considering doesn’t give an amp rating, you'll be able to calculate its current capability by its wire gauge. The lower the gauge, the upper the wire’s capability. Follow these tips:
This is often not a downside when you plug an appliance directly into an outlet using its factory wire as a result of the manufacturer has sized the twine appropriately for the electrical current demand, or load, that the appliance requires. But if you utilize an undersized extension cord to increase the reach of that appliance cord, you'll be able to exceed the safe load capacity of the extension twine, and therefore the result can be disastrous.
