Difference Between Wooden Casing Capping Wiring and Lead Sheathed Wiring

Wooden casing and capping wiring systems are suitable for low voltage domestic installation and here we are using VIR or PVC wires are used while in Lead sheathed wiring system that uses conductors that are insulated with VIR and that are covered with an outer sheath of lead aluminum alloy which contains about 95% almost lead.  Here this post gives the main key difference between wooden casing capping and leads sheathed wiring system to better understand this topic.

What is the wooden casing capping wiring system?


Wooden casing capping wiring system was famous in the wiring system in the past. This cable is used in kind of wiring were either VIR or PVC or any other approved insulated cables. The cable was carried through the wooden casing enclosures. The casing is made up of a strip of wood with parallel grooves cut lengthwise so as to accommodate some VIR cables. The capping used to cover the wires and cables installed and fitted in the casing.

What is lead sheathed wiring system?


The lead sheath is earthed at each and every junction to provide a path to ground for the leakage current. They are fixed means that of metal clips on wooden battens. The wiring system is very expensive. It is suitable for low voltage applications.


A key difference between wooden casing capping and lead sheathed wiring system:

  • The cost of a medium in a wooden casing capping wiring system while in lead sheathed wiring system cost is high.
  • Both of the wiring the voltage is low around 250 V.

  • The fixed switchboard at the proper height.
  • Use earth wire of proper gauge.
  • Make use of copper conductor.
  • Always replace wires that show signs of deteriorations.
  • You should never touch any plumbing or gas pipes while working with electricity and its because they are may time used to ground electrical system.
  • A proper plan to ahead for any type of wiring.
  • Don't exceed the load on a circuit.
  • If you overload outlets or extension cords it's going to create a fire hazard.
  • Never utilize damaged wiring or elements.
  • Before you do any electrical work make sure that the power is off at the breaker.
  • A voltage tester is a cheap life insurance policy when working with high voltage.
  • It is easier and faster to complete your wiring if you make sure you have got all the tools you require and always use the suitable tools.
  • Do you conceal conduit wires is used in wall, you will never spics wires together and conceal them within a wall without a junction box, it is a fire hazard. So put in an accessible junction box for the connected wires.
  • When you work with electricity. You should never touch or try repairing any electrical appliances or circuits with wet hands. 
  • Never use an aluminum or steel ladder because if you are working on any receptacle at hight in your home. An electrical surge will ground you and the whole electric current will pass through your all body. so use bamboo.
  • Never use any equipment with frayed cords, and damaged insulation or some broken plugs.

Some essential tips to avoid MCBs tripping

One very common cause for the breaker to trip is a loose electrical connection and can easily be corrected by tightening them, SO try to reset it once by turning it to off position and then back to the on position. Not even an MCB but all the circuit breaker can trip at regular intervals due to any of the following reasons:


Why MCB trip Frequently? 


The most important point is overload circuit, short circuit, and Ground fault, that three-point of  MCB trip frequently.

1. Overload circuit:

The overloading is the most common reason for the circuit breaker trip. It indicates that the household has many heavy power appliances that are being used at the same time on the same circuit. When we have to use too much heavy power appliances are used together on the same circuit, there is more electricity creating an overload.

2. Short circuit:

A short circuit is one of the most dangerous problems in life, and it can happen at any time and anywhere. In all the cases, almost the problem of circuit breaker tripping is also caused by short circuits. This problem happens when a wire or phase touches another wire or phase or touches a neutral wire in the circuit. A high current flows when these two wires touch creating heavy current flow, more than the circuit can handle this flow. 

3. Ground fault:

This is also the biggest problem of MCB tripping. Faulty ground wiring can lead to hot wires touching the ground wire. When this problem happens, it can cause the circuit breaker to trip. 


Here some essential trip to avoid MCB tripping:

  • We should unplug all the devices when it's not in use.
  • We should make sure that none of your appliance cord is damaged or broken.
  • We should be aware of how many appliances are plugged in during hot or cold weather.
  • The most important point to avoid using the extension cable and the power strips if you have few outlets.

Why MCB is better than fuse?

The most important advantage of using MCB abbreviation called a miniature circuit breaker is that the power supply can be resumed almost immediately. MCB can be changed over the switch needs to be pushed backed to the On position. While in the case of the fuse, the whole wire will have to be replaced first and there are also have some disadvantages of fuse like it has low breaking capacity, and it has slow compared to other circuit breakers. So here this post gives information about several advantages of MCB over fuse or we can say that why we have to use MCB better than a fuse.

Here we have to list several advantages of MCB over fuse:

  • MCB is more sensitive to current than a  uses fuse.
  • MCB is very simple to resume to the supply.
  • MCB is better and safer from the fuse.
  • In the while uses of MCB, the faulty zone of an electrical circuit can be easily identified.
  • MCB provides a better interface than a fuse.
  • MCB is reusable whereas a fuse needs to be replaced.
  • MCB has less maintenance and less replacement cost compare to fuse.
  • MCB doesn't have any wire, so it can be used at any time.
  • It better than fuse because of when the heavy current passed these switches which automatically off.
  • Handling  MCB is electricity safer than handling a fuse. In the case of MCB.

How many types of MCB are there?

MCB is classified according to the tripping over the rage of fault current. It is most important for you to know what type of MCB trip curve to decide what type to use for different appliances for the correct electrical system. Before learning about type first understand the trip curve. Trip curve is essentially nothing but the maximum current that particular MCB can withstand. Here there are six different types of MCB, which are A, B, C, D, K, and Z. Let us check detailed information one by one below.

Types of MCB: 


Type A trip:

These type of MCB are highly sensitive to short circuit and are used for the protection of semiconductor devices.  MCB with class A trip characteristics trip instantaneously when the current flowing through it reaches between 2 to 3 times the rated current. 

Type B trip:

This type of trip off when the current flow is 3-5 times the actual flow and These MCB finds a use for cable protection.

Type C trip:

Type is C trip is most suitable for domestic and residential application ad electromagnetic starting with a medium starting current. this type of trip is off when the current flowing through it reaches between 5 to 10 times the rated current. 

Type D trip:

Type D MCB has high resistance, MCB with high-class D trip instantaneously when the current flowing through it reaches between above the 10 to 20 times the rated current. It is most suitable for inductive and motor loads with high starting currents.

Type K trip:

This type of  MCB withstand up to 8 to 12 times the initial charge and thus can be used for bulky load devices. It is suitable for inductive and motor load with high inrush currents.

Type Z trip:

This type of MCB is most suitable for highly sensitive to short circuit and that is used for the protection of highly sensitive devices such as semiconductor devices. MCB with class Z trip, the current flow through it reaches between 2 to 3 times the rated current.

What is electrical wiring

As we all know the wiring system is dangerous for life, it is a potentially dangerous task if done improperly. There are many different types of electrical wiring systems. Let us look at the different types of electrical wiring that are used in home electrical and some domestic properties. Wiring technology will help to understand a few basic terms used in describe wiring. Electrical wiring is one type of conductor., which is a material that conducts electricity. In our home application, most of the wire is used in the insulated, meaning that they are wrapped in a nonconductive plastic coating. 

Let we have to understand the basic home electrical wiring and domestic electrical wiring types: 

Conduit wiring:

 Conduit wiring is provided by mechanical protection and also provides electrical safety to persons and property and provides convenient and accessible ducts for the conductor. As well designed electrical raceway system has adequate capacity for future expansion and readily adaptable to changing some conditions. 

Casing capping wiring:

 Casing capping wiring is one of the oldest methods for the wiring system and it has been very popular is frequently used. In today's world, after post introduction of the conduit or sheathed wiring system, it is preferred for the wiring system. 

Concealed conduit wiring:

 The concealed conduit wiring system is the most popular, most common type of house electrical wiring used. Conduit wiring is a professional way if wiring a building and domestic wiring

Batten wiring system:

 This is when a single wire or some group of wire is laid over a wooden batten. The wires are held to the batten using a brass clip and spaced at an interval of 10 cm for horizontal runs and 15 cm for vertical runs.

 Lead sheathed wiring system:

 Lead sheathed wiring system that uses conductors that are insulated with VIR and that are covered with an outer sheath of lead aluminum alloy which contains about 95% almost lead. This metal sheath gives protection to cables from cables mechanical damage, atmospheric corrosion, and moisture.

 Cleat wiring:

Cleat wiring comprises of PVC insulated wires or ordinary VIR that are braided ad compounded. This type of wiring is most suitable for temporary wiring purposes such as in marriage halls, some events, etc so the most important advantage of this wiring system is it saves labor cost and installation cost. This type of wiring can be very easily installed and materials can be recovered for further use.

SSD is a mass storage device that stores the data on non-volatile memory. Solid-state means that doesn't require moving part. while in HDD, called hard disk drive, there are no moving parts to an SSD. There are many more advantages of SSD as that it is the faster access time, low power consumption and noiseless operations. SSDs are also known as flash drives or solid-state disks. Solid-state drive connected to the computer through standard IDE or SATA connections. 

Advantages and disadvantages of solid state drive

SSD stands for solid-state drive, There is a trend that has been seen in the use of SSD replacing the traditional drive in many types of electronic devices. It became more attractive as an enterprise for data storage devices like desktops, laptops, servers, PCs, etc. While the hard disk is smarter, faster, reliable today than ever before, SSD has several features that make them viable alternatives. There are as many advantages to doing this as there are disadvantages or demerits making it difficult to choose a clear winner. So let us take a closer at the merits and demerits given below.

Advantages of solid-state drive(SDD):

  • A solid-state drive consumes less power as compared to a hard disk drive. 
  • Though the cost of hardware is lower with HDDs, the cost of bandwidth is much lower with SSDs.
  • SSDs allow faster booting of computers as the drive is not required to spin up thereby improving the performance of the computer.
  • SSD produces less noise because it uses computer chips and there are no moving parts. Since it is non-mechanical, there is virtually no more noise.
  • Solid-state drive lack motors, they generate less heat, unlike HDDs. This is an important feature for people using laptops as it allows them to use their laptops with more comfort o their laps for longer time periods with the least worry about burns.
  • The solid-state drive has better-reading ad and writing speed. Data reading and writing to flash chips occur instantly in SSD, allowing the SSDs to have better reading and writing speeds.
  • The constant read performance feature makes file fragmentation simple and a nonissue in an SSD. Data can be accessed anytime in an instant regardless of where it is stored.
  • SSD has no moving parts, It can keep the data safe in the event of dropping it. SSD is no mechanical failure in higher mechanical reliability. The SSD is lighter than an HDD and is resistant to shock and temperature change.

Disadvantages of solid-state drive(SDD):

  • One of the biggest disadvantages of a solid-state drive is the cost. SSD costs are much more than a conventional hard disk drive.
  • The SSDs are using DRAM technology and require more power, unlike conventional HDDs. These drives continue to consume power when the system starts while a conventional hard disk drive will not.
  • A solid-state drive is highly expensive and solid with a hefty price tag, unlike conventional HDDs.
  • Some of the solid-state drives especially those using NAND memory flash chips can be written only for a limited number of times. Solid-state drive using DRAM technology does not come with such a limitation, they cost more.
  • Some of the less expensive solid-state drives, especially the MLC-based types, come with slower write speeds when compared to read speeds. These speeds are relatively lower write speed on the conventional hard disk drive.
  • In recent times, the use of SSDs has increased leading to various issues. These issues have to e resolved before obtaining optimal performance from SSDs.
  • The Windows operating system that was used before Windows 7 were not optimized for SSDs. It reduced the drive performance and shorten its lifespan.
  • The SSD write/ erase cycle is limited. An HHD can stand up to a 1 to 5 million write cycle, whereas, An SSD averages 100000 cycles, meaning a decrease in the SSD performance over time. This limitation in write cycles causes more trouble.  
  • The inability to recover old data is one of the biggest disadvantages of SSD.
  • SSDs can access data quickly, they usually take more time to save data. The device on the SSD must first delete the old data in order to write the new one. This is a big disadvantage, which mostly goes unnoticed by an average user, for data systems that are involved in the transfer of large amounts of data.
  • In this drive, the data is permanently and completely deleted from the drive, though this is an advantage in terms of data security, still, permanent data deletion could lead to irreparable consequences in certain events where there is no backup for deleted data.
  • Due to the unique file system structure of an SSD, data extraction can be an extremely difficult and lengthy process.
