Prepare the feeder cable as detailed for the type of joints and the joint kit to
be used.
Cut the conductors to length ensuring that the joints will be staggered within
the joint shell. The outer sheath must project at least 50 mm into the joint shell
in the finished joint and no crimp joint should be closer than 75 mm to the end
of the shell.
Remove 12 mm of insulation from each core.
Slide a rubber grommet over the core.
Prepare loop tail ends as in section 3.2.4. If one tail end only is to be crimped
in a crimp sleeve, remove 24 mm of insulation from the tail and double the
end back prior to crimping. This will ensure that a secure crimp is made.
Insert the prepared core and tail end(s) into opposite ends of the crimp
sleeve, allowing a 2 mm protrusion at each end and crimp both ends of the
sleeves using the correct crimping tool. The crimps must be made in the same
plane.
Position the rubber grommet in the centre of the crimped sleeve and visually
inspect the completed crimp to ensure that no loose strands are present.
Apply a pull test to each crimp joint.
Complete the assembly of the joint in accordance with the appropriate
section.
