Here is a simple method on how to terminate cables:
- The cable should be cut to a suitable length for the conductor tails.
- To make it easy to strip the cable, make sure it has been cut flush and square. If there is PVC covering the sheathed cable, ensure that it is cut back before stripping the copper sheath.
- Mark the copper where the sheath is going to be stripped in order to expose the conductors.
- Now remove the sheath, making sure the cable ends are still cut off square and free from burrs.
- Clean conductors, making sure that all extra magnesia has been removed.
- After preparing the cable for termination, it is vital that termination is completed as soon as possible in order to avoid moisture build up, which could reduce its insulation resistance reading.
