A cable assembly is described, for safely connecting an electrical power source such as an electrical outlet at an airport, to a power consuming device such as an aircraft. The assembly includes an electrical cable (18) with a connector (16) at one end for engaging the receptacle on an aircraft to supply power thereto, and a relay (30) at the inner end of the cable which can connect and disconnect a power source to the cable. "On" and "off" power switches (32, 34) are located near the outer end of the cable. The "on" switch enables a workman to operate the remote relay to turn on the power immediately after he has connected the outer end of the cable to the power consuming device. This encourages the workman to apply a voltage to the cable only after the connection is made, to avoid sparks that might ignite flammable fumes. The cable also includes two switches (102,126) near its outer end for operating a motor that extends or retracts the cable from a cable storage device, the motor operating only while the switch continues to be manually depressed. This assures that the workman will hold the connector end of the cable above the ground while winding it up, to avoid damage to the outer end of the cable.
