For general knowledge about lines, bundles and arrangements, please refer to line_arrangement=* page for global guidelines.

As per IEC 466-05-07, bundles of the line are arranged vertically but middle elements may be slightly shifted horizontally, on their support. It covers at least two patterns:

• Top and down bundles are on a strict vertical axis and middle elements slightly shift left or right.
• Bundles are along an oblique axis forming an angle of less than 45° with the vertical.

Any other possibility would lead to triangular
Vertical arrangements are very often on one support side. Consider triangular when bundles are installed on either side of their support.
