To prevent home fires and other electrical accidents when using extension cords, follow these guidelines:
- Use an extension cord only as a temporary connection.
- Check the ampere rating - abbreviated "A" or "amps." The appliance plugged into the extension cord should not exceed that rating. (An appliance’s amps equal its wattage divided by 110.)
- Use a heavy-duty, grounded, three-pronged cord when working with power tools.
- Always check cords for frays, cracked insulation and damaged plugs.
- Don't use lamp-type extension cords (No. 18 wire) for any device drawing more than 7 amps. Use a heavy duty cord with No.16 or No.14 wire instead.
- Don't run extension cords across foot traffic areas or near water.
