What is a service life of a screw wire nut connector СИЗ?
If you have done the connection in accordance with all recommendations, the connectors will serve you as long as the cable. How to make a good connection, what are the rules:
- The quality of the screw wire connector should be high. Chose a manufacturer with a good reputation and a guarantee that the spring will not drop out together with the screwed wires.
- Compare the cross-section range of the connector with the cross-section of the wires you need to connect. Trying to put big wires inside a smaller connector is useless.
- Do not make a preliminary screw of the wires with pliers. Put the wires inside the connector and turn it clockwise, be careful and do not damage the thread. If you will deal with connectors with necessary care and attention, they will serve you for a long time.
