A flat wire extension cord includes an elongated cord, a first connected attached to a first end of the elongated cord, and a second connected attached to an opposite end of the elongated cord. The elongated cord includes at least one electrifiable conductor for delivering electrical power, first and second insulating layers formed on opposing sides of the at least one electrifiable conductor, and first and second return conductors formed on the first and second insulating layers, respectively, such that said at least one electrifiable conductor is at least substantially entrapped by said first and second return conductors. The first connector is operable to connect the conductors of the elongated cord to a line side input, and the second connector is operable to connect the conductors of the elongated cord to a load.
