- Casing Capping Wiring Definition: Casing capping wiring is defined as a system where PVC insulated wires are placed in a plastic or wooden channel and covered with a cap.
- Components: This system uses channels and caps made of plastic or wood, typically in white or grey, and available in standard lengths.
- Installation Process: The process involves cutting channels to size, screwing them to walls, placing wires inside, and covering with a cap.
- Types of Wires Used: Common wire sizes include 0.75 mm², 1 mm², 1.5 mm², 2.5 mm², and 4 mm² copper wires.
- Use of Joints: Elbow joints and tee joints are used at corners and junctions to ensure proper alignment and connectivity.
This is one of the simpler forms of electric wiring systems. It is an older, more conventional system that we still occasionally use today. In casing capping wiring, PVC insulated wires are placed in a plastic casing and covered with a cap. The casing has a rectangular cross-section as shown.
The casing channels and caps are usually white or grey. They are typically made of plastic or wood. These channels and caps come in standard manufacturer lengths, commonly about one meter or two meters.
In casing capping wiring, we first cut the casing channels and the capping cover to the required length. Then we screw them onto the wall according to the wiring layout, typically at fixing intervals of no more than 60 centimeters.
After that, we place the PVC insulated 0.75 mm2, 1 mm2, 1.5 mm2, 2.5 mm2 or 4 mm2 copper wire in the channel as per our requirement.
After all this process, we cover the channel with the cap.
The wire laying work for the casing capping wiring is now finished.
We can fit the channels in both vertical and horizontal alignments. For corners and junctions, we use elbow joints and tee joints, respectively.
