Not if you count the 3 or 4 LOR PC units that I just connected cords for.
I am still figuring out the process. It is still taking a long time to get it right.
Here is the short list of steps.
Stripping back and extra 2 inches of insulation on the cords. (done ahead of time)
Twisting and snipping extra wire on the 3 leads.
Crimping the ring connector for the ground.
Cutting and then grinding the "fingers" so that the clamps will be able to screw in tight.
Getting the 3 holes drilled for the clamps.
Drilling and mounting the ground post.
Squeezing 8 fat 16 gauge cords into a 1" hole twice. Baby powder works wonders here.
Screwing down the wires seems to take the longest for me since I get paranoid about the wire not coming out. The connector does not seem to hold the wire tight unless I feel like I am overtightening it. That is the other reason that I felt that I needed the strain relief.
My first LE that I added the strain relief to is a ugly, but I made it work since I don't really want to redo it. The picture was my second attempt.
