I've never been a fan of jubilees on lead, always makes me nervous. The good thing about enwl kit Is that it's not tight pressure to the lead but it's more than enough to create a good and secure bond, especially with the mesh around the lead and the braid tied into it before the roll springs are applied. I've worked across multiple dnos over the years and find enw to have the best jointing techniques and terminations compared to other DNO'sFrom the two DNO's in the areas I work the shrink kit and braid earth is ENWL's solution which is quite neat and tidy while SP Energy Networks use something similar to a "jubilee" clamp around the PILC for the earth with a 6491x 16mm earth cable connected to it and a sheet rubber self adhesive wrap around it which looks quite bulky and a bit rough
