Here are a few tips to help you make the right choice. When choosing your extension cord, take note of the gauge or size of the wire it is made of. A heavier gauge wire will have a smaller or lower number. For example, a 12 gauge wire would be larger, and can therefore power larger wattage appliances than a 14 gauge wire. Purchase the correct gauge of cord to meet your needs as some power is always lost due to resistance (voltage drop) as it travels down the length of the cord. For example, a 12 gauge extension cord, up to 100 feet in length, can safely power a 12 amp circular saw. A 14 gauge cord can only be 60 feet long, and a 16 gauge cord can be no more than 35 feet long to provide sufficient power for the same saw. If you are going to use an extension cord to power two or more appliances you must add the total wattage rating of all connected appliances to determine which gauge size you will need. This is an important tip for all those students heading off to college or university, who are planning to solve all their electrical needs with the use of one power bar extension. Overloaded extension cords can get hot enough to burn. Never run extension cords under carpets or rugs and always uncoil a cord that is in use to prevent possible overheating. Check cords occasionally for damage. A nicked cable or damaged cord end is dangerous. Discard it and replace it with a new cord. Never use an indoor rated extension cord outdoors although the reverse is acceptable. Extension cords that can be used outdoors are clearly marked "Suitable for Outdoor Use". Using a cord which is not designed to withstand the elements could result in an electric
