Abstract
An installation test system has a control device and one or more hand-held test devices. The control device and the one or more hand-held devices are in wireless communication via respective communication systems. The control device performs typical pre-power tests including insulation testing and ground testing. There is at least one hand-held device dedicated to testing for residual current in circuit breakers and another hand-held device dedicated to testing for loop impedance. The control device records all test data and stores data in storage.
