- 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’s an older, more conventional system. Nowadays, we still occasionally use casing capping wiring. In this system, 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 lengths, commonly 1 meter, 10 feet, and 6.5 feet.
In casing capping wiring, we first cut the casing channels to the required length with the capping cover. Then we screw them onto the wall according to the wiring layout. Usually, we insert screws every 30 cm in the channel.
The 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 the process we cover the channel by cap.
The wire laying work for the cashing capping wiring is finished.
We can fit the channels in both vertical and horizontal alignments. For corners and junctions, we use elbow joints and tee joints, respectively.
