An airfield series circuit includes a transfer relay having first and second sides, and a primary regulator operatively coupled to an airfield series loop of an airfield at the first side of the transfer relay. A standby regulator is operatively coupled to the airfield series circuit at the second side of the transfer relay. The transfer relay is movable between a primary mode of operation whereby the first side of the transfer relay closed directing lighting power to the airfield series loop from the primary regulator and the second side of the transfer relay open isolating the standby regulator from the airfield series circuit, and a standby mode of operating whereby the second side of the transfer relay closed directing lighting power to the airfield series loop from the standby regulator and the first side of the transfer relay open isolating the primary regulator from the airfield series circuit.
