An electrical power extension cord having a male plug end, a female receptacle end, and an insulated flexible cordset extending between the male and female ends of the extension cord. The male end has a first prong electrically connected to a hot wire contained in the cordset, a second prong electrically connected to a neutral wire in the cordset, and a third prong electrically connected to a ground wire in the cordset. The female end has a first receptacle electrically connected to a hot wire contained in the cordset, a second receptacle electrically connected to the neutral wire in the cordset, and a third receptacle electrically connected to the ground wire in the cordset. Continuous electrical current and ground monitoring circuits are contained in the male and female ends of the extension cord. Activation of indicator lamps contained in the monitoring circuits continuously indicates both electrical current and ground continuity between the male and female ends of the extension cord and electrical current at the male plug end.
