Below is a list of Power Cords manufacturers from Fremont, California. Power cords are lengths of conductive materials which supply electrical energy from a main power source to a piece of electrical equipment, or an electrical appliance. Power cords are typically flexible, although for certain uses can be semi-rigid, and consist of a cord with electrical plugs at each end, one male, and one female. The female plug is connected to the piece of equipment or appliance while the male plug connects to the electrical receptacle or outlet.
