The Energy Commission from February 25,2015 would ban electricians without wiring certificate from the Commission. It is part of measures to regulate the operations of electrical engineers to uphold professional standards and protect life and property.

"Very soon all electricians would have to be certified by the Energy Commission, go through an exam before you are certified, if you don't have a certificate you cannot parade yourself as such" Victor Owusu, Public Relations Officer(PRO) for Energy Commission said.

All new buildings across the country without wiring certificates will have their power-supply cut off from the national grid.

The commission has in this light instituted a certification scheme for electricians across the country. The PRO, Victor Owusu says electricians who fail to comply with the directive would be prosecuted.

According to Victor Owusu, the initiative is in conjunction with the Fire Service. " We also realise that most of the fire recently was a result of faulty wiring and inferior cables".

Electrical wiring has a lot to do with the safety of persons and property because faulty wiring consequently causes a lot of fire outbreaks among others.

The Electrical Wiring Regulation 2011 (LI 2008) passed by Parliament in 2012 has three key objectives: Who qualifies to engage in any electrical wiring of properties in Ghana, how wiring is done and the kind of materials used to wire properties in the country he said.

With effect from February 25, 2015, newly built structures that are not wired by certified electrical wiring professionals (CEWPs) will not be connected to the national grid.

The Electrical Wiring Regulations, 2011 (LI 2008) come into force on February 25, 2015.

The Executive Secretary of the Energy Commission, Dr Alfred Ofosu Ahenkorah, who made this known in Accra yesterday, said offenders of the regulations would be dealt with according to the law.

At a graduation ceremony for new CEWPs, he said the commission was collaborating with the Electricity Company of Ghana (ECG) and other service providers to ensure the full implementation of the law.

The Electrical Wiring Regulations, 2011 (LI 2008) was passed by Parliament on February 24, 2012.

The key objectives of the regulations are to guide professionals who engage in electrical wiring and installation works in the performance of their duties and to ensure safety of lives and property.

The regulations specifically provide for issues related to who qualifies to undertake electrical wiring in the country.

Regulation 7 says: A person shall not undertake electrical wiring on premises unless that person is certified by (a) a licensed electricity distribution utility; or (b) a recognised person appointed by the Energy Commission.

From February 25, 2015 all new buildings across the country without wiring certificates will have their power-supply cut off from the national grid.

According to the Energy Commission, this is part of measures to regulate the operations of electrical engineers to uphold professional standards and protect life and property.

The commission has in this light instituted a certification scheme for electricians across the country. The Principal Programme Officer, Solomon Sarpong told JOY BUSINESS, electricians who fail to comply with the directive would be prosecuted.

The certification programme seeks to inject some professionalism into the electrical wiring industry. Electrical wiring has a lot to do with the safety of persons and property because faulty wiring consequently causes a lot of fire outbreaks among others.

The Electrical Wiring Regulation 2011 (LI 2008) passed by Parliament in 2012 has three key objectives: Who qualifies to engage in any electrical wiring of properties in Ghana, how wiring is done and the kind of materials used to wire properties in the country he said.

He added To enforce this, the Commission has tied the exercise to service connections. In this regard, if a facility is not wired by a Certified Electrical Wiring Professional (CEWP), who will eventually, issue an Installation Completion Certificate, the facility will not be connected to the national grid by the Electricity Company of Ghana.

The Chandler Unified School District (CUSD) Governing Board met Wednesday night and approved the K-6 Wireless Expansion Project for all elementary schools throughout the district.

Overview of the K-6 Wireless Expansion Project includes: installation and cabling of 1,000 Access Points; Wireless Management Suite for all devices and Aruba Care Support for one year; and Aruba ClearPass Access Manger Sever, licensing, and support.

Superintendent Dr. Camille Casteel spoke to members of the board about how the K-6 Wireless Expansion Project will be implemented throughout the 28 elementary schools in the district.

Knox Gifted Academys wireless expansion has already been completed.

The K-6 Wireless Expansion Project will cost a little more than $1 million, which will be taken from the bond election and a gift from Intel thats specific to technology expansion within the district.

Weve utilized those funds to help pay for services for our schools and support the technology efforts, she said. We still have money in the gift fund that will cover this. We thought that this was an excellent use, rather than delay this another two years deepening on the success of a bond election.

Casteel anticipates the expansion will be completed before the start of the 2015-16 school year.

The wireless implementation across all our elementary schools allows us to present more viable solutions to having a less-distributive-testing environment on a campus versus hard-wiring, said Dr. Matt Strom, executive director of research and accountability. We can be a lot more innovative with how we schedule assessment, and thats why I think wiring all the elementary schools is a necessary step in becoming ready even though its not necessarily required.

Method of Wiring - for Three Phase DOL Motor

The Main contactor has three NO contacts and one NO and NC Auxiliary contacts. A thermal overload relay is shown in the example but one can use only a contactor without the overload unit. If a thermal overload unit is used, it's rating should correspond to the motor running amperage.

Install the 415 V coil contactor in a suitable enclosure and fix the On/Off Push Button switches at the required operating point.

Wire from a 3 Phase power supply of a 3 Pole MCB or a Main switch of the Power Distribution to the L1,L2 and L3 terminals of the contactor. If a Thermal overload is connected to the contactor's T1,T2 and T3 terminals, then connect the load wires to the motor to the T1,T2 and T3 terminals of the thermal overload.

Now for the control wiring.

Connect a wire to L1 terminal and connect the other end to a terminal of the On Push Button.

Connect the other terminal of the On Push Butto to the terminal of the Off Push button.

The remaining therminal of the OFF Push button should be wired to one of the Thermal Overload's NC contact terminal.

The other terminal of the Thermal Overload's NC contact should be wired to the coil terminal A1 of the contactor.

[ If a Thermal overload is not used, then the remaining therminal of the OFF Push button should be wired to A1 terminal of the contactor.]

What is meant by an Electrical Installation ?

An electrical installation can be simply described as a system consisting of electrical components such as conductors and switchgear to work electrical equipment to fulfill a specific purpose, safely.

Examples for electrical installations are numerous around you.

The Electrical system of your house, the plant room of a swimming pool, a factory with few or many electrical equipment, a workshop with machinery, the services of a multi storied building consisting of Electrical equipment- all these can be cited for electrical installations.

The root of generating Electricity for various requirements of the mankind today is numerous. Major methods of Electrical Power Generation are Thermal, Hydropower, Nuclear ,Solar and Wind Power.

The generated power is distributed through an Electrical Distribution system.

The Power Utility Companies or government Power Utility Institutes take the responsibility of bringing the Electrical Power to the Consumer.A Consumer can be a large Production Industry or a basic Home of a person.

The Consumers requirements vary greatly according to his electrical power requirements or the useage of Electricity.

Electrical Installations are needed for the Consumer to use Electricity for his requirements such as Lighting, Heating and Air Conditioning , running all types of Electrical Equipment , to name a few.

All of us at one time or another, needs the services of Electrical Installers to attend to either new installation work or to maintain existing electrical installations.

If you are looking for pictures of temporary electrical installations, they can be found at another post, Temporary electrical installation picturesandTemporary lighting installation pictures.What you will find below are mostly on permanent installations. Picture 1 Conduit and trunking

The above picture shows how the electrical conduit and trunking installation should be coordinated with water pipes.

Trade subcontractors (water piping sub-contractors, electrical sub-contractors, telephone cabling contractor, computer network contractor, etc) must not be allowed to proceed with the installation of their individual services and equipment on the first come, first served basis.

=== RELATED POSTS:Pictures of electrical wiring|

About the author:http://www.linkedin.com/in/electricalengineerforhire ===================

Prior to the commencement of the installation works by trade sub-contractors, a set of proper coordinated drawings, endorsed by all relevant parties, should be made available to all the sub-contractors involved in a particular area.

Feedbacks from them should be heard because they are the ones who will be doing the works. Many times, what are nicely shown on approved drawings cannot be practically constructed at site.

You will find more pictures on this matter in Electrical conduit and trunking pictures.

The following few pictures and diagrams show the connections of the 1-phase ELCB unit inside a house electrical panel. They are for readers who wish to understand how the electric shock protection devise is connected to their house electrical wiring.

The leakage current (or leakage voltage) usually occurs when there is a defect in a part of the installation, which can be caused by faulty components or by injuries to the insulation of the wiring, cables, electrical appliances or other accessories such as the switches and socket outlets.

When there is leaked current that exceeds the preset value of the ELCB setting, the ELCB then breaks the connection of the incoming electricity supply from the internal house wiring.

This is done automatically within a fraction of a second of the leakage being detected, before the magnitude of the leakage current reaches a level that can cause serious injuries or electrocution.

With a proper use of ELCB, the possibility of serious injuries due to electric shock to a person who accidentally come into contact with energized metal casing of an appliance is minimized.

B. ELCB circuit

An ELCB is not a simple component. Inside the casing of the ELCB unit you can see in Picture 2 above are a number of components. These components are assembled together and wired into a small electrical circuit with a dedicated purpose.

Diagram 3 below shows the internal circuit of a single phase ELCB. This type is one of the most commonly used type in house electrical panels.

However, before I go further, a few points need to be kept in mind throughout this article.

1. When it first came to be used, the ELCB was actually a voltage-operated device that was designed to detect a current leaking through the earth path of electrical equipment and appliances.

Barbed wire, also known as barb wire, less often bob wire[1][2] or, in the southeastern United States, bobbed wire[3]), is a type of steel fencing wire constructed with sharp edges or points arranged at intervals along the strand(s). It is used to construct inexpensive fences and is used atop walls surrounding secured property. It is also a major feature of the fortifications in trench warfare (as a wire obstacle).

A person or animal trying to pass through or over barbed wire will suffer discomfort and possibly injury. Barbed wire fencing requires only fence posts, wire, and fixing devices such as staples. It is simple to construct and quick to erect, even by an unskilled person.

The first patent in the United States for barbed wire was issued in 1867 to Lucien B. Smith of Kent, Ohio, who is regarded as the inventor.[4][5]Joseph F. Glidden of DeKalb, Illinois, received a patent for the modern invention in 1874 after he made his own modifications to previous versions.

Barbed wire was the first wire technology capable of restraining cattle. Wire fences were cheaper and easier to erect than their alternatives. (One such alternative was Osage orange, a thorny bush which was time-consuming to transplant and grow. The Osage orange later became a supplier of the wood used in making barb wire fence posts.[6]) When wire fences became widely available in the United States in the late 19th century, they made it affordable to fence much larger areas than before. They made intensive animal husbandry practical on a much larger scale.

An example of the costs of fencing with lumber immediately prior to the invention of barbed wire can be found with the first farmers in the Fresno, California area, who spent nearly $4000 (over $75,000 in present-day dollars) to have wood for fencing delivered and erected to protect 2500 acres of wheat crop from free-ranging livestock in 1872.[7]

Fencing consisting of flat and thin wire was first proposed in France, by Leonce Eugene Grassin-Baledans in 1860. His design consisted of bristling points, creating a fence that was painful to cross. In April 1865 Louis Franois Janin proposed a double wire with diamond-shaped metal barbs; he was granted a patent. Michael Kelly from New York had a similar idea, and proposed that the fencing should be used specifically for deterring animals.[8]

More patents followed, and in 1867 alone there were six patents issued for barbed wire. Only two of them addressed livestock deterrence, one of which was from American Lucien B. Smith of Ohio.[9] Before 1870, westward movement in the USA was largely across the plains with little or no settlement occurring. After the American Civil War the plains were extensively settled, consolidating America's dominance over them.[10]

Ranchers moved out on the plains, and needed to fence their land in against encroaching farmers and other ranchers. The railroads throughout the growing West needed to keep livestock off their tracks, and farmers needed to keep stray cattle from trampling their crops.[11] Traditional fence materials used in the Eastern U.S., like wood and stone, were expensive to use in the large open spaces of the plains, and hedging was not reliable in the rocky, clay-based and rain-starved dusty soils. A cost-effective alternative was needed to make cattle operations profitable.[12]

The "Big Four" in barbed wire were Joseph Glidden, Jacob Haish, Charles Francis Washburn, and Isaac L. Ellwood.[13] Glidden, a farmer in 1873 and the first of the "Big Four," is often credited for designing a successful sturdy barbed wire product, but he let others popularize it for him. Glidden's idea came from a display at a fair in DeKalb, Illinois in 1873, by Henry B. Rose. Rose had patented "The Wooden Strip with Metallic Points" in May 1873.[14]

This was simply a wooden block with wire protrusions designed to keep cows from breaching the fence. That day, Glidden was accompanied by two other men, Isaac L. Ellwood, a hardware dealer and Jacob Haish, a lumber merchant. Like Glidden, they both wanted to create a more durable wire fence with fixed barbs. Glidden experimented with a grindstone to twist two wires together to hold the barbs on the wire in place. They were created from experiments with a coffee mill from his home.[14]
