3. 1. Cleat Wiring
⢠This system of wiring comprise of ordinary VIR or PVC insulated wires
⢠Cleat wiring system is a temporary wiring system therefore it is not
suitable for domestic premises.
⢠The use of cleat wiring system is over now a day.
⢠The cleat has a two parts.
1. Base
2. Cap
⢠The cables shall be supported on base
⢠the base is covered with cap and then cap is screwed on the base.
⢠The cleats are available in two-way, three-way and four-way construction.
4. ⢠The distance between two cleats is kept approximately 0.5 meter
⢠The cables are entered in junction box through holes
⢠The life period of this wiring is
1. Minimum 3 months
2. maximum 10 to 15 years.
ADVANTAGES :
⢠cheap wiring system.
⢠Easy installation.
⢠Most suitable for temporary use
⢠Materail can be retrieved for reuse.
⢠Skilled man power not required.
⢠Flexibility provided for inspection & expansion
5. Disadvantages :
⢠Appearance is not so good.
⢠Higher risk of mechanical injury.
⢠Open system of wiring required regular cleaning.
⢠It is not reliable and lasting
⢠Only used on low temperature
6. 2. BATTEN WIRING
⢠In this system, wires sheathead in tough rubber are used which are quite
flexible
⢠They are clipped on wooden battens with brass clips.
⢠Fixed on the walls by flat hard screws.
⢠These are moistured and chemical proof cables.
⢠Brass pins spaced at an interval of 10cm for horizontal runs and 15cm for
vertical runs.
CTS / TRS WIRING :
⢠They are suitable for damp climate
⢠Not suitable for outdoor use
⢠TRS wiring is suitable for lighting in low volatge installations.
7. Advantages :
⢠Wiring installation is simple and easy
⢠Cheap as compared to other electrical wiring systems
⢠Paraphrase is good and beautiful
⢠Repairing is easy
⢠Low risk of short circuit
Disadavantages :
⢠Danger of mechanical injury.
⢠Danger of fire hazard
⢠Skilled workman are required
⢠Should not be exposed to direct sunlight.
⢠Only suitable below then 250V
⢠Need more cables and wires.
8. FLUORESCENT TUBE
WORKING :
COMPONENTS WE USE :
Electrical components for single tube light installation we use are;
1. CHOKE (Electromagnetic ballest)
2. STARTER (Small neon lamp)
3. SWITCH &WIRES.
⢠It is not connected in the main supply directly.
⢠It operates at 230V
INSTALLATION
⢠From the junction box the neutral wire is not taken out to the switch
board
⢠It is taken out from the junction box and carried out to the port 2 of the
tube light
⢠The live wire or phase is taken from the junction box to the switch board.
9. ⢠The live wire is connected to the one terminal of the switch.
⢠One terminal of the choke or ballest is connected to port 1.
⢠Other terminal is connected to the pin1 of terminal 1
⢠One end of a starter is connected to pin 2 of terminal 1
⢠Another end of starter is connected to to the pin 2 of terminal 2.
