1.2 The tasks directed to the trainee and the objective of the training:
I was expected to understand and understand the directed training plan that was developed for me and my fellow trainees, and to prepare reports to show the extent of my understanding of the planned plan and discuss it with the engineer in charge.
As for the goal of the training, the training objectives can be summarized as
follows :
-The ability to acquire theoretical knowledge through study and apply it in practice.
-Identify the nature of the labor market and its needs.
-Cooperate with co-workers and always attend
-Examine the electrical systems and electrical communication standards, and get acquainted with the elevator room.
Chapter Two: Distribution Panel:
2.1 Introduction to Distribution Panel:
A distribution board (also known as a panelboard, breaker panel, electric panel, DB board, or DB box) is an electrical power supply system component that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a single enclosure.
A main switch is typically included, as are one or more residual-current devices (RCDs) or residual current breakers with overcurrent protection (RCBOs) in newer boards.

2.2 Design to Distribution Panel:
It can be used as a door to decorate your home.
2.3 How Does the Distribution Panel Work?
When the main power source is turned on, energy is delivered to the various distribution panel components. Circuit breakers, relays, contactors, and other components on the panel function as switches, controlling the flow of power to the facility's various loads. In addition, the panel monitors the flow of electricity and will trip the circuit breaker if the current exceeds the preset limit.

The distribution panel also safeguards electrical equipment and employees against potential electrical risks. Circuit breakers serve as an effective safety element, tripping in the event of an overload or short circuit. This both protects the electrical equipment and decreases the risk of electrical shock. Because it has vital
applications, distribution panel makers work diligently on it.
Chapter Three: Cables
3.1 Introduction to cables:
The cables are vital because if the wires are not good enough, the electrical efficiency would be poor.
3.2 Type of Cables:
Electric cables
Figure 4 Electric cables
▪ 4 mm sectional area: utilized for small load equipment such as (lamps - switches)
▪ Sectional area 6 mm: utilized for heavy-duty equipment such as (air conditioning)
electric cables carry
The cables carry we utilized to transfer electric cable to load without affecting any environmental considerations.
There is tow type:
1- Sold cable.
Figure 5Sold cable

We used to move electric cable from distribution panel to room because most connections are made by line and are difficult to rotate.
2- Flexible carry
Figure 6 Flexible carry
We used to distribute cables in rooms and living rooms as well because these areas contain numerous rotations and connections, and this cable can be employed in this scenario .
Chapter Four: Connection electric standers
4.1 Introduction connection electric standers:
As we stated in the corporate massage, quality is the most crucial aspect in results, and good quality will not be achieved until international standards are met, which we observed in time training.
4.2 light load standers :
1. Used to define light unit light has weatherproof feature.
2. Used to have a waterproof feature in kitchen and bathroom lights.
3. Connect the switch light in series with the fuse.
4.3 Electric sockets standers:
1. 1-Install at least two sockets in each room.
2. Keep the height of the socket to no more than 25 cm.
3. Connect an original socket using a conductor with a cross sectional area of 2.5cm and a 16a breaker.
4. the line of phase connects on the right and the neutral connect on the left.

Chapter Five: The concrete compression Test
5.1 the purpose of the experiment:
The purpose of the experiment is to verify the resistance of concrete to compressive forces and its conformity with the design resistance, by applying compressive force on concrete samples of standard shapes and dimensions. One experiment (number:
6 samples) is conducted for every (100 cubic meters) of concrete.
5.2 Tools used in the test:
Test molds: They are cylinders or cubes according to the standard specifications in our case:
1: Metal Cube Mold (20cm*20cm*20cm)
2: The compaction rod: It is a metal rod with a length of (60-50 cm) and a diameter of (16 mm).
✓ The cube molds must be completely clean, and it is preferable to coat them with a thin layer of oil before pouring in order to prevent them from sticking to the
concrete and to facilitate the removal of the molds the next day.
5.3 Devices used in testing the compressive strength of concrete
:1- We take a sample of freshly mixed concrete at the site and fill (6) cube molds with concrete so that they are filled in (3) layers and each layer is compacted separately, either with a vibrating machine or manually by means of a compaction bar with a number of (25-35) times so that the number of blows is distributed. Regularly on the surface of the concrete until the concrete is completely compacted, and after the completion of compaction of the upper layer, its surface is leveled with the surface of the mold by means of a ruler.
2 - The molds filled with concrete shall be stored immediately after pouring away from sunlight in a place free of vibrations. The relative humidity of the air in this place shall be no less than 90% and the temperature shall range between 15-20 degrees Celsius for a period of (24) hours.
3- Learn the concrete samples, then remove them from the moulds, immerse them in pure water, and leave them until just before the test. This water must be renewed every seven days, and its temperature must be kept constantly, and the samples remain completely immersed in water until the date of testing.
4- The third samples are usually tested after (7 days) and the other third after (28 days) by testing the pressure loads after taking them out directly from the water while they are still wet to know the strength of the concrete at each age, so that the cubes are placed between the two surfaces of the pressing machine and a regular load is applied to them.
5- In the testing machine, the axis of the sample should be in line with the axis of the machine head. When using the cubic sample, the two sides of the sample must be the same as the two surfaces of the machine head, which are the two faces opposite the inner surface of the metal mold.

Chapter six: Rules and ethics of practicing the engineering profession
The engineer’s professional reputation is built on the efficiency and value of the service he provides, and he also avoids unfair competition with others.
-The engineer seeks to develop his personal abilities and capabilities while providing professional development opportunities for engineers and technicians working under his supervision .
-The engineer is committed to promoting the basic values and principles of engineering ethics and establishing them in society, and his actions are committed to methods that support and enhance the profession’s status, integrity, and dignity locally and globally.
In professional affairs, the engineer is the zealous agent of his employer and must avoid any conflicts of interest .
- In presenting his ideas, opinions and decisions, the engineer is careful to be objective, honest, and within his field of expertise and expertise.
In providing professional services, engineers seek to apply the highest standards of safety and environmental protection for the public interest of individuals and society.
Chapter Seven : Conclusion Recommendations :
7.1 Conclusion:
At the end of this training, I can summarize what I learned in several points as follows :
-We conclude that the submitted contractor is responsible for making decisions -Providing useful information in my field of specialization.
-The engineer must observe the ethics, rules and ethics of the profession, and while carrying out his work, he must develop relationships with colleagues, citizens and employers - whether he represents the private or public administration, or the owner or contractor of a development project and protects himself from problems and builds and develops himself .
7.2 Recommendations:
In conclusion, I extend my thanks to all the supervising engineers and my fellow future engineers, and I hope that I have succeeded in fully presenting this report, which included information, and I ask God that we have presented this report in the correct manner that would benefit all readers who will read it. this report .
In the end, I hope that the report will receive satisfaction and acceptance, and we ask God Almighty to benefit us with what He has taught us and increase our
knowledge. You have my sincere thanks and appreciation .
