What is Concealed Wiring ?

     No comments

Material Used in Concealed Wiring

Same materials are used in concealed wiring as conduit wiring.

Procedure of Concealed Wiring

Concealed wiring is properly named as concealed conduit wiring. It is very laborious to install. The layout of this wiring is done under the plaster of the wall of the building. Conduit pipes are buried under the plaster of wall with GI wire inside. After, with the help of GI wires, the main PVC insulated cables are drawn through the conduit.

Advantages of Concealed Wiring

    2. Class B conduit: thick sheet of steel high gauge conduit
    Non-Metallic Conduit 13, 16.2, 18.75, 20, 25, 37, 50 and 63 mm (diameter) PVC conduit.
  • VIR or PVC insulated cables
  • GI wire of 18SWG
  • Screw
  • Coupling
  • Elbow
  • Rigid off set
  • 2-hole strap
  • Lock nut

Procedure of Conduit Wiring

This kind of wiring is not easy to install. On the surface of the wall or ceiling conduit pipes (with GI wire inside) are attached with help of 2-hole strap and base clip at a regular certain distance. Next GI wire is used to lay down the wires through the conduit pipe. conduit wiring

Advantages of Conduit Wiring

The main advantages are
  • The safest wiring
  • Appearance is better
  • No risk of fire or mechanical wear and tear.
  • No risk of damage of cable insulation
  • Safe from humidity, smoke, steam etc.
  • No risk of shock
  • Long lasting

Disadvantages of Conduit Wiring

What is Batten Wiring ?

     1 comment

Material Used in Batten Wiring

  • CTS or TRS cable
  • Straight teak wooden batten (at 10 mm thick)
  • Tinned brass link clip ( buckle clip)
  • Brass pins

Procedure of Batten Wiring

Group of Single or double or three core cables are used to be laid on straight teak wooden batten. The cables are hold with help of tinned brass link clip or buckle clip. Brass pins are used to fix the buckle clips on the wooden batten. Buckle clips is fixed with brass pin on the wooden batten at an interval 10 cm for horizontal runs and 15 cm for vertical runs. batten wiring

Advantages of Batten Wiring

The advantages of this kind of wiring are given below.
  • Easy installation
  • Cheap in material cost
  • Appearance is better.
  • Customization is easy
  • Less chance of leakage current

Disadvantages of Batten Wiring

The disadvantages of batten wiring are
  • Not suitable for outdoor wiring
  • Humidity, smoke, steam etc directly affect on wires.
  • Heavy wires are not recommended for this wiring scheme.
  • Only suitable for below 250 V.
  • High risk of fire.

What is Casing Wiring ?

Material Used in Casing Wiring

  • VIR or PVC insulated wires
  • Casing Enclosure (made of wood or plastic)
  • Capping (made of wood or plastic)
  • Casing and capping joints.

Procedure of Casing Wiring

This kind of winding is very old fashioned. Generally PVC or VIR insulated wires are carried through the casing enclosure and capping is used to cover the casing. casing wiring

Advantages of Casing Wiring

Advantages of this kind of wiring scheme are
  • Cheap and easy to install
  • Strong and durable wiring
  • Customization can be done easily
  • Safe from smoke, dust, rain and steam etc.
  • Due to casing and capping no risk of shock.

Disadvantages of Casing Wiring

There are some disadvantages in casing wiring; they are
  • Very costly
  • Not suitable for weather with high humidity and acidic conditions.
  • Insect like termites or ants can damage wooden casing and capping.
  • High risk of fire.

What is Cleat Wiring ?

Material Used in Cleat Wiring

  • VIR or PVC insulated wires
  • Weather proof cables
  • Porcelain cleats or plastic cleats (two or three grooves)
  • Screws
cleat wiring

Procedure of Cleat Wiring

In this wiring VIR or PVC insulated wires are braided and compounded on walls or ceiling with the help of porcelain cleats. The wires can be weather proof. Simple wire laying is done in this scheme of wiring. In present days, this kind of wiring scheme is not recommended for house or building. Only in temporary army campus or festival related pandels this wiring is used. cleat wiring

Advantages of Cleat Wiring

There are some advantages of this type of wiring.
  • Cheap and easy wiring
  • Easy to fault detection
  • Easy to repair
  • Alteration and addition is easy.

Disadvantages of Cleat Wiring

The disadvantages of this wiring are
  • Bad appearance
  • Exposed to weather to be affected by humidity, rain, smoke, sunlight etc
  • Chances for shock or fire
  • Used in only 220V in low ambient temperature.
  • Not long lasting
  • Sag happens

What is Electrical Wiring?

Electrical wiring is the electrical power distribution through the wires in a perfect manner for economic use of wiring conductors inside a room or building with better load control. Electrical wiring system is classified into five categories:
  • Cleat wiring
  • Casing wiring
  • Batten wiring
  • Conduit wiring
  • Concealed wiring

How to wire lamp connected in series ?

     2 comments
These all Lights/lamps are connected in series. Each lamp is connected to the next one. The flowing current is same in all these incandescent bulb /lamps but the voltage are different.
Good To know: This is not a suitable wiring for home or building. Because the effect will be that two or more lamps will be very dim, and removing one lamp will cause others to go out. 
Disadvantages of  this circuit.
  • the failure or removal of any single lamp will break the circuit and cause all of the others to stop working.
  • As more lamps are added, they will all be reduced in brightness. because voltage are shared in series circuit. 
Advantage:

  • Less size of wire cable is required in this type of wiring.

WHAT IS ELECTRICAL ENGINEERING ???

     No comments
Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. This field first became an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use. Subsequently,broadcasting and recording media made electronics part of daily life. The invention of the transistor, and later the integrated circuit, brought down the cost of electronics to the point they can be used in almost any household object.
Electrical engineering has now subdivided into a wide range of subfields including electronics, digital computers, power engineering, telecommunications, control systems, radio-frequency engineering, signal processing, instrumentation, andmicroelectronics. The subject of electronic engineering is often treated as its own subfield but it intersects with all the other subfields, including the power electronics of power engineering.
Electrical engineers typically hold a degree in electrical engineering or electronic engineering. Practicing engineers may haveprofessional certification and be members of a professional body. Such bodies include the institute of electrical and electronics engineers (ieee) and the institution of engineering and technology (professional society) (iet).
Electrical engineers work in a very wide range of industries and the skills required are likewise variable. These range from basic circuit theory to the management skills required of a project manager. The tools and equipment that an individual engineer may need are similarly variable, ranging from a simple voltmeter to a top end analyzer to sophisticated design and manufacturing software.
