The main advantage of concealed wiring than the surface conduit wiring is that:
It requires less material
Fault location and rectification is easy
Installation cost is less
Inspection more easy
It requires less material
Concealed conduit wiring is a method where conduits are embedded within wall plaster or concrete during the construction phase of a building. The primary advantage is the aesthetic appeal and reduced reliance on external surface-mounted hardware, which generally leads to a reduction in the total quantity of external conduit and clamping materials required.

LtotalтАЛ=тИСLrunтАЛ тАФ Represents the total material requirement, which is minimized in concealed systems by optimizing internal pathways.
During building construction, PVC or GI conduits are laid out according to the circuit plan. Once the structural work is done, cables are pulled through these pre-installed paths. Because the conduits are housed inside the structural elements, the length of external piping is minimized compared to surface-mounted setups that require extensive horizontal and vertical runs across exposed walls.
Concealed wiring offers better protection against mechanical injury and environmental hazards.
Fire risk is reduced as cables are protected within concrete or masonry.
The primary drawback is the difficulty in accessing wiring for future modifications or fault location compared to surface systems.
Installation requires high precision and coordination with civil work.
Aesthetically superior as no wiring is visible.
Reduced risk of mechanical damage or tempering.
Higher safety against fire and environmental corrosion.
Difficult to detect or rectify faults.
Extremely difficult to change or expand wiring layout later.
High initial installation cost due to structural integration.

Concealed wiring is preferred in modern interior design for safety and aesthetics, whereas surface conduit is often used in industrial or factory settings where frequent maintenance is required.
Option B (Fault location) is actually a disadvantage of concealed wiring. Option C (Installation cost) is typically higher for concealed wiring due to the labor-intensive slotting and plastering requirements.
A is correct тАФ It requires less material as it integrates into the building structure, avoiding extensive surface piping runs.
Always remember that in IE Rules, concealed systems prioritize safety and aesthetics, whereas surface systems prioritize maintainability and modularity.
