We will now learn about open wiring. Because it is safe and easy to do channel wiring at home. To do a house wiring first you need to know how many points there will be in that house. The points of the house where lights, fans, televisions, etc. are connected are called individual points.
A house usually has five points. However, points may be more or less as required. The owner of the house decides where the lights, fans and sockets for the TV will be. And according to this point the mechanic calculates the goods. For example- how many wires of any size will be needed, how many channels will be needed, how many switch birds and switches will be needed etc.
It is worth mentioning here that it takes approximately 40 yards to wiring a house measuring 12 feet by 15 feet. It takes 6 channels. It takes 3/4 of the switch. It takes 2 sockets, 2 holders and 2 ceiling ranges.
How to make point and joint box space
First decide how many points and joint boxes there will be in a room. Suppose a room has five points and a joint box. The way to do the wiring in this case is mentioned below:
The space on the wall through which the channel will go to its various points, first mark the space with the help of colored chalk or pencil. Then mark with a screw point pencil to attach the channel to that spot.
Screws are usually inserted one foot apart to attach the channel to the wall. Then measure the spot with measuring tape or gauze tape. Calculate how many inches or how many feet the channel will take from one point to another. Cut the bottom of the channel to size with a hack-blade.
Have a drill machine, channel Racal plug, screw and driver and a tool at hand. Because all these things will be needed while doing house wiring. Channels and joint boxes are usually placed eight feet above the walls from the floor of the house. And the switch bearing is installed four and a half feet above the wall from the floor of the house.
How to place the channel on the wall
To wiring the house, you have to put the channel on the wall first. Then you have to connect the electric wire through it. Now we will know how to put channel on the wall
Take the hand drill machine. Attach a wall bit of size 8 mm to the face of the machine. Then place the face of the drill bit on the point marked with pencil or chalk.
Then turn the handle of the machine to the right and make a hole one and a half inches in the wall. Insert the Racal plug into the hole.
Open the channel cover. Now hold the bottom of the channel along the bottom of the mark on the wall. Then mark along the screw point on the channel with the head of the pencil or screwdriver.
Now place the channel on a piece of wood. Then drill holes at the marked points along the middle of the channel. Then place the channel along the hole in the wall. Then take a one inch inch screw. Insert the screws through the hole in the channel along the hole in the wall. Then fasten the screws on the channel with a screwdriver. Place the bottom of the channel according to this rule all over the walls.
During wiring, sometimes 2 wires are pulled through the channel. If two wires are pulled, there will be a quarter of an inch channel. Sometimes you have to pull 4 to 5 wires through the channel. 4/5 wire pulls will take 1 inch wide channel. And if you want to pull more than 4/5 of them, it will take one and a half inch channel.
Now start installing channels from the main switch.
Connect the channel from the main switch to the joint box and bring it to the bottom of the joint box. Now take a joint box measuring four inches by four inches. The joint box has two screw points.
Open the top lid of this box. Then place the bottom of the box on the wall and mark the two screw points on the wall. Now remove the bottom part of the box from the wall. Then drill a hole in the wall with a drill machine. Now insert the Racal plug into the holes and place the joint box on it. Then insert 2 screws along the hole in the joint box. Then fasten the screws with a screwdriver.
Place another channel on the other side of the joint box and bring it up to the point of the bulb on the wall. Hold the batten holder at the end of this channel. The batten holder has two screw points. Mark the screw points of the holder on the two walls. Then drill with the drill machine at the marked place on the wall.
Now place the required channel from the joint box to the socket point as before. Then take the bottom of the socket point switch bar. Now screw the lower part of the switch bird to the wall like the lower part of the joint box. From this socket point all electrical equipment is run.
Tube light points
Take a half inch channel. Place the channel from the left side of the joint box to the point of the tube light. Take the ceiling raj banana box in hand. Now place the ceiling ridge box on the wall just below the channel. Then mark the screw point of the box on the wall for mounting on the ceiling ridge wall. Now drill the walls.
After drilling, take the frame of rod light or tube light. Place the frame horizontally 6 inches below the ceiling ridge. Now mark the 3 screw points of the frame on the wall with a screwdriver.
Take a half inch channel. Place the channel from the top of the joint box to the point of the fan. Now take a box of ceiling rage. Mark the screw point on the wall for installing the ceiling ridge box as per the previous rule. Then drill the walls and install the ceiling ridge.
Take the channel one and a half inches wide. Place the channel one and a half inches from the bottom right of the joint box to the main switch bar. In other words, place the channel up to the switch board which will have switches and sockets for fans, lights etc. Then attach the lower part of the switch board to the wall as per the previous rule.
