| Video Discription | A low loop impedance is important for the protective devices to operate quickly in case of a short circuit. At the point of supply it should be below 0.4 ohms. In a domestic installation at a wall socket, value should be below 1 ohm. It surprised me that the loop impedance was more than 1.3 ohms with the two, six way power boards plugged into each other |
