Is there any requirement that the cable will be placed in the wireway?
40% but the buried tube is longer, or elbow, need to enlarge the diameter.
Can also be used, from the picture point of view can be used, FireWire (red line) This is absolutely no problem, only a little bit of skin injury, this all right. And then the zero line (blue line) has a big problem, you can make the ground line to zero line, zero line to do the ground, if this is just an ordinary outlet, then I absolutely did not ask this method is passed by my own test Several times, hundred percent of the line.
The main screen (shield) is to prevent the overall (whole root) cable core by the outside of the electromagnetic interference, split screen (shield) can prevent the cable within the wiring harness between the mutual electromagnetic interference Figure
Basically the same, but you go to the car shop is best to say to the brake line or variable speed line, because the two lines of the thread shape is not the same
