Mark Extension Cords with Right Amperage to Protect Your Power Tools

A power cord labeled with its amperage to prevent an overheated motor Mark your power cords so you remember what amperage it carries. Recently, I learned the hard way that the extension cord you use for a tool must be capable of supplying the maximum amperage the tool requires (as indicated on the motor label). I overheated the tool motor because my cord was too long for the necessary amperage. Since this information isn’t stamped on the cord, I now write the cord length and amp rating near both plugs of my new cords with a marker. I’ll never ruin another power tool again.
