Long extension cords require increased conductor size to compensate for voltage drop. Smaller gauge cords are thicker; 10 ga. can handle more amperage than 12 ga. of the same length. The chart below combines cord length and example device amperage requirements, to indicate what wire gauge you need in an extension cord.

Electrical voltage is the separation of electric charges and the current flow due to the directed movement of electrons between two points. This electron movement always causes heat. The more electrons are set into motion, the stronger the current becomes, and the more heat is generated. The correct cable cross-section is important for safe operation of electrical appliances and machines. The electrical wire size is crucial in thi…
