Correct option is C
TRS Wiring:
·
TRS (Tough Rubber Sheathed) wiring is specifically designed for electrical installations that require a flexible, durable, and well-insulated solution. It consists of a core of copper conductors, which are insulated with rubber, and an outer protective rubber sheath.
·
Flexibility and durability: TRS wiring is known for its flexibility, which makes it easy to install in tight spaces or areas that require bending. The rubber sheath provides protection against mechanical damage, moisture, and chemical effects, making it suitable for various environments.
·
Suitability for low voltage installations: Due to its insulating properties and mechanical strength, TRS wiring is particularly suited for low voltage lighting installations, where safety and insulation are critical.
Other Wiring Types:
·
Surface conduit wiring: Involves running electrical wires inside conduits that are mounted on the surface of walls or ceilings. While this method is safe and provides good protection for the wires, it is often used in industrial or commercial settings rather than low voltage residential lighting.
·
Concealed conduit wiring: This type of wiring involves embedding conduits within walls or ceilings, keeping the wiring hidden. It's commonly used for higher voltage installations and provides excellent protection and aesthetics but might be overkill for basic low voltage lighting.
·
Casing wiring: This is an older method where wires are run inside wooden or plastic casings fixed on walls. It offers less protection compared to conduit wiring and is less commonly used in modern installations due to aesthetic and safety concerns.
