The required number of wires per connection (+12V DC and 0V) can also be easily determined on the basis of
the following diagram.
The "pointer" refers to the sample calculation. According to the calculation, the vertical pointer at the point of
intersection shows 150 mA/150 m or just below 6 wires of diameter 0.6 mm or more than 3 wires of diameter 0.8
mm. Rounded up to whole wires, this comes to 6 wires with a wire diameter of 0.6 mm or 4 wires with a wire
diameter of 0.8 mm, as yielded by the calculation.
