The invention relates to an electric by-pass panel meant to be used in low-voltage electric installations. According to the invention, the panel comprises two circuits, the first circuit comprising two switch separators (), a device for the automatic switching in of the reserve (), which comprises a generator contactor () and a network contactor () and a generator (), this circuit permitting a consumer () to be connected by means of the network contactor () to a supply network () under normal operation conditions and, by means of the generator contactor () to the generator (), under emergency conditions, the second circuit comprising a switch separator () connected through an interlocking cable () to the first switch separator () which permits the consumer () to be connected to the supply network () in case the device for the automatic switching in of the reserve () is disconnected, where the interlocking cable () prevents the undesired closing of the first switch separator () at the same time with the switch separator () of the second circuit, which consists of an external metal jacket () wherein a control cable () can slide, the interlocking cable () being securely fixed at its ends in some stop pieces () mounted on some flanges () and being provided with some end pieces () by means of which the control cable () can serially actuate the switch in/off hooks of the switch separators () which it connects. |
