The next time you reach for an extension cord, remember this: just because a particular cord is long enough, it’s not necessarily the right one for the job.
Power extension cords aren’t all the same. They are manufactured to be used for different purposes, and to carry varying amounts of electrical current. By basing your choice of extension cord on each task’s requirements, you can greatly reduce the risks of fire, electrical shock, and injury that come with improper use.
Extension Cord Safety Tips
Don't use near sinks, bathtubs, or other water areas
Remove plugs from the outlet by pulling firmly on the head of the plug
Disconnect cords that become heated
Use the appropriate cord for the load to avoid over-heating
Minimum 8 gauge wire (lower the gauge, the heavier the wire)
Many cords are rated for specific tasks - check the label
Use only exterior approved extension cords outside
Don't allow a wire octopus of extension cords in any electrical outlet.
