Electrical Building Installation

1. For any type of building before we start the construction, or to start a construction, the following types of drawings or designs must have prepared and then we should have to get a permission from the concerned authority. 1) Architectural Design , AR 2) Structural Design, ST 3) Electrical Design (Installation), EL 4) Sanitary (Water) Work Design, SN Main Requirements of Building Construction

2. COURSE CONTENTS Introduction of Electrical Installation (Objectives, General Installation work and Procedure of Electrical Installation) Electrical Installation (Design Work) for Residential, Commercial and Industrial Applying Auto CAD Cost estimation, Contract document preparation(Bill of Quantity) and Preparing Electrical Report ELECTRICAL INSTALLATION EACT 4034

3. 1) Instructs and guides electricians in performing the required wiring and electrical equipment installation. Objectives/Aims/ of Electrical Installation

4. 2) Provides the owner with an “as-built” record of the installed electrical wiring and equipment for the purposes of maintenance or planning future expansion. The owner then becomes responsible for recording all wiring and equipment changes Objectives of E lectrical Installation

5. 3 ] Describes the electrical project in sufficient detail to allow electrical contractors to use the drawings in estimating the cost of materials, labor, and services when preparing a contract bid. Objectives of E lectrical Installation

11. 2 ) Locate Socket Out Lets for the convenient and necessary places. And also locate power socket outlets for the convenient place. Power socket outlets will supply from individual ACB and cable Procedure of EL…….

12. 3 ) On the plans, locate bell push buttons, tele outlets, TV outlets, signal apparatus such as phone outlets, speakers, microphones, fire and smoke detectors, and so on the appropriate and convinient places . For this we should have to use their graphical symbols of EBCS Procedure of EL…….

13. 4 ) Design the lighting for the facility of installation. This step is complex and involves a continued interaction between the architect, the owner and the lighting designer. Arrnange the lighting in to sub groups. Under floor duct and ceiling track systems would be shown at this stage. Flash and surface mounted installation would be shown also at this stage. Procedure of EL…….

14. 5 ) In cooperation with the local electric utility, decide upon the point of service entrance, service voltage and metering location (KWHM) and others. L ocate the Main Distribution Board (MDB) to the appropriate place with Switch board or KWHM and with SDB Procedure of EL…….

15. 6 ) Depending on the type of facility, it may be necessary to separate the lighting layout from the receptacle and signal device layout for the sake of clarity of the plans. Procedure of EL…….
