This document discusses different types of electrical wiring used in domestic and industrial settings. It begins by introducing wiring and its purpose of smoothly distributing electricity with safety. The main types of wiring discussed are cleat, batten, casing capping, conduit, and PVC wiring. Common wires used for domestic wiring include VIR, CTS/TRS, weatherproof, lead-covered, MICC, and PVC wires. General rules for domestic wiring include having a cut-out, using weatherproof wire for service connection, protecting each line with a fuse, and having separate subcircuits for lighting and power loads. Diagrams of single-phase, three-phase, and panel wiring are also included.

4. Introduction:
• Wiring is systematic laying of wires for the smooth
flowing of electricity current at different utility places
with utmost safety and precautions.
9. Cleat Wiring:
•It fit on the wall.
•Distance of half meter between two cleat.
•Vulcanized Indian rubber wire used.
•Temporary used.
•Wire are in the open atmosphere.
10. Batten wiring
1. P.V.C Wire
2. TRS/CTS Wire
3. Lead Sheath Wire
Wooden Casing Capping
Wiring
1. It fit on the wall with help of
screw.
2. It protect wire against mechanical
damage, Moisture, dust.
11. PVC casing capping wiring
1.It become popular,
2.Less cost,
3.Easily fault detect
4.Appearance of wiring is good,

14. Weather proof wire
•It made waterproof by drooping it
into waterproof compound
•It is useful for service connection
15. Lead covered wire
•No effect of moisture on it
•It used where there is moisture
presence.
16. Mineral insulated copper covered
•Coating of magnesium oxide is
provided.
•Less effect of temperature.
•Copper sheath is provided.
•It is used in mines, factory,
refinery, furnace, boiler, rolling,
mill est.
17. Poly Vinyl Chloride wire
•Dielectric strength is more
•Mechanical strength is more
•Life is long
•Protect against flame
•Protect against oil, alkali
•PVC wire is widely used
19. . General rules of domestic wiring.
1. Cut-out on consumer’s premises.
2. Meters, maximum demand indicators and other apparatus
on consumer Premises.
3. Weatherproof wire for service connection with sufficient
current carrying capacity.
4. All conductor/wire should be sage in all term of voltage
rating with proper insulation
20. 5. Every line or phase should be protected by suitable
ratings fuse.
6. In metal conduit wiring metal conduit pipe
continuously earthed.
7. Each load point an appliances should be a
independent control switch.
8. In any building. the wiring installation, there must be
separate sub circuits for light/fan/3 pin socket load
and for 3 pin socket 15 Amp. power load.
21. 9. In any light/fan and the number of load points
connected in one sub circuit should be less than
10(ten).
10.In any power sub circuit, the maximum should not be
more than 3000 watts and the number of power point
should be up to two only.
11. The rating of fuse in any circuit should not be less
than half the capacity of the lowest size cable. In any
sub-circuit the fuse rating should not be more than 5
amp.
22. 12.The earthed terminals of all 3 pin sockets outlets and plugs
should be permanently connected to the earth wire.
13.Sufficient number of 3 pin socket outlets should be provided
at suitable places in all rooms of the building.
14.In the bath rooms. the 3 pin socket should be at a height of
not less than 1.5 m.
15.All ceiling fans are to be hung 2.75 m above the floor level
refer IS :4648 -1968.
23. 16.In the domestic wiring earth wire should be of 14 SWG GI
for single phase supply and for 3 phase supply system earth
wire must be of 8 SwG GI.
17.If the load on any domestic wiring installation exceeds 6.0
kw. then 3 415 v. 50 Hz, 4 wire supply should be used. The
load on 3 phases should be properly balanced.
18.when the covered area in the building complex is more than
5000 m2 and the total load is more than 1000kva. The
separate sub station is required to be installed.
