Highly skilled labour is required in
TRS wiring
Casing capping wiring
Conduit wiring
Both conduit and casing capping wiring
Both conduit and casing capping wiring
Highly skilled labor is required for both conduit wiring and casing capping wiring because these methods involve precise structural installation, cutting, fitting, and alignment. Proper execution ensures mechanical protection, aesthetics, and long-term electrical safety, which cannot be achieved by unskilled workers.

Conduit wiring requires bending pipes, threading, and securing rigid or flexible metal/PVC channels, while casing capping requires accurate groove formation, miter joint cutting, and screw alignment. Both demand specialized tools and mastery of installation techniques to maintain the integrity of the insulation and mechanical enclosure.
Conduit wiring provides excellent mechanical protection and is fire-resistant but expensive.
Casing capping wiring is preferred for domestic indoor applications due to ease of inspection.
TRS (Tough Rubber Sheathed) wiring is simpler and requires less technical expertise compared to conduit.
Skilled labor reduces the risk of short circuits and insulation damage during installation.
Conduit: High mechanical protection and durability.
Casing Capping: Easy to inspect and add new circuits.
Conduit: High cost and time-consuming installation.
Casing Capping: Not suitable for outdoor or damp locations.
Conduit: Industrial plants and commercial buildings.
Casing Capping: Surface domestic wiring in dry, clean rooms.

TRS (Tough Rubber Sheathed) wiring is a surface system using vulcanized rubber cables, often used in temporary or simple installations, making it less demanding than rigid conduit systems.
Conduit systems (like Rigid Steel Conduit) require specific tools such as pipe benders, reamers, and threading dies.
D is correct тАФ Both conduit and casing capping wiring necessitate specialized labor for ensuring correct mechanical protection, cable routing, and precise structural finishing.
Always prioritize safety regulations (like IS standards) for conduit installations, as poor workmanship leads to high-resistance joints, resulting in overheating.
