A circuit testing closer may include a fault isolating switching device coupled between a supply side and a load side of a power distribution system and a current pulse generator coupled in parallel to the switch to generate a current pulse within the power distribution system subsequent to a fault isolation for testing the power distribution system. The current pulse generator may include an electromechanical actuator, an electromagnetic actuator or a solid state switching device. The circuit testing closer may be a purpose-built combination device, or the fault isolating switching device and the current pulse generator may be separately coupled and commonly controlled devices. The fault isolating switching device may have continuous current rating greater than a continuous current rating of the pulse generating device.
