Which wiring is recommended only for temporary installations?
Cleat
CTS/RTS
Metal
PVC conduit or PVC capping
Cleat
Cleat wiring is specifically recommended only for temporary installations due to its exposed nature and lack of mechanical protection. It involves supporting insulated cables on porcelain or wooden cleats at regular intervals.

The principle relies on mechanical support using cleats mounted on walls or wooden beams. Since the wires are neither enclosed nor shielded from external environmental factors or mechanical impact, they are prone to physical damage, moisture ingress, and accidental human contact, making them unsuitable for permanent building interiors.
Used mainly for construction sites or temporary exhibitions.
Highly economical but lacks durability and aesthetic appeal.
Not suitable for damp or highly corrosive environments.
Requires frequent inspection due to physical exposure.
Extremely low installation cost
Easy to install and dismantle
Fault location is easily identified visually
High risk of mechanical damage
Poor aesthetic finish
Susceptible to weather, moisture, and dust
Higher risk of fire or electric shock compared to enclosed wiring
Construction sites
Temporary exhibitions or pandals
Small workshop environments where permanent wiring is not viable
Cleat wiring uses VIR (Vulcanized Indian Rubber) or PVC insulated cables.
Option B (CTS/RTS) refers to Cab Tyre Sheathed or Tough Rubber Sheathed wiring, which is a bit more robust but still rarely used today compared to conduit.
Option D (PVC Conduit) represents the modern standard for permanent internal house wiring.
A is correct тАФ Cleat wiring consists of exposed cables supported by cleats, making it strictly suitable for temporary purposes rather than permanent fixtures.
For permanent installations, always prioritize conduit wiring (PVC or Metal) to ensure compliance with IE Rules and to provide necessary mechanical and fire protection.
