Horizontal Direction
In interior electrical wiring, supply lines are installed in a horizontal direction along the walls, usually at a height of approximately 30 cm from the ceiling or 15 cm from the floor for skirting conduits. This practice ensures uniformity, ease of maintenance, and avoids mechanical damage by keeping wires away from common furniture or wall decor paths.

The horizontal layout follows the standard practice of concealed or surface conduit wiring. By maintaining a constant horizontal alignment, wiremen can easily trace circuits, avoid cross-interference, and maintain the aesthetic integrity of the building interior while ensuring compliance with safety standards (e.g., IS: 732).
Horizontal runs minimize the length of conduit required for multi-room wiring.
Vertical drops are restricted to localized areas, typically near switch boards and sockets.
Uniform horizontal alignment simplifies the detection of faults using continuity testers.
Conformity with building codes prevents accidental drilling into conduits during post-installation work.
Aesthetic consistency in interior design.
Easier to perform 'rewiring' by pulling wires through junction boxes.
Increased cable length compared to diagonal paths.
Requires more junction boxes at corners.
Residential electrification (surface and concealed conduit).
Commercial office cable management systems.
According to the Indian Standard (IS: 732), wiring should be run in straight horizontal or vertical lines to facilitate identification.
Vertical runs are primarily reserved for connecting horizontal runs to power points at floor level or light switches at shoulder height.
C is correct тАФ Supply lines in electrical interior wiring are standardly installed in a horizontal direction to maintain structural order and facilitate maintenance.
Always remember that while horizontal lines are for distribution, vertical lines represent the 'down-drops' to switches and sockets, not the main supply paths.
