Figure A.2
Cable clamping methods
Strapping your cable to a DIN rail, as shown in Figure A.2 (the cable
labeled B) is crude, but just as effective. The DIN rail is raised off the
panel slightly by using washers to allow nylon cable ties to pass
underneath. The table below lists advantages and disadvantages of
strapping the cable to the DIN rail.
Plain copper saddle clamps, as shown in Figure A.2 (the cable labeled
C) are sold for plumbing purposes, but are very effective and available
in a range of sizes.
