You're on a site and the wire gauge keeps changing. You need 1.5 mm here, 10 mm there, red for phase, clear where you want to see the joint underneath. Pulling out six different boxes is a waste of time you don't have. This pack puts 160 lengths across six diameters and three colours into one storage case so your first grab is always the right one. 40 black + 10 red + 10 clear at 1.5 mm, 25 black + 5 red + 5 clear at 2.5 mm, 17 black + 4 red + 4 clear at 3 mm, 14 black + 3 red + 3 clear at 5 mm, 6 black + 2 red + 2 clear at 6 mm, and 6 black + 2 red + 2 clear at 10 mm. Built for the technician who's wiring a switchboard at 4 pm and doesn't want to hunt for the 2.5 mm black. Add to cart and it ships from our AU warehouse
